Rain was originally meant to appear in Mortal Kombat 3, but didn't actually appear until Ultimate Mortal Kombat 3. Rain was originally a red herring inserted by the game developers; a character shown in the game's attract mode who did not actually exist within the game itself. A recent interview reveals that the insert was made by Ed Boon himself to intentionally trick players. Many MK fans searched for him in vain, with the eventual realization of his status as a joke character (named after a Prince song, "Purple Rain") dawning. The joke expands further when it is revealed that Rain is a "prince" himself. He would, however, soon make an actual appearance in the console versions of Ultimate Mortal Kombat 3, and Mortal Kombat Trilogy as a full-fledged character with his own history (that of a traitor to his realm) and move set, to the delight of many fans and the chagrin of others.
Originally depicted as a purple garbed ninja, Rain's heritage as both an Edenian and the revelation of his divine blood has him incorporate more regal themes into his overall appearance, mainly gold, jewelry, and even a cape. His mask in his later appearances also bears a gold crown or tiara like attachment, further reinforcing his self-proclaimed royal status.
Power and abilities
Being the half-god he is, Rain wields immense power. Rain can control two things that involve weather: water and lightning. His powers being related to such, he is able to pressurize jet streams of water to either propel himself or slice his opponents like a blade. Rain's control over water and lightning is so powerful he can create massive storm clouds to block out the sun from the sky. He is most noted for his ability to trap opponents in a spherical prison of water that gives him limited control over their body. In addition, he is able to conjure up lightning blasts from the sky to blast his opponents into the air. He also possesses the ability to liquefy himself, turning himself into water and reconstituting behind them in a swift manner akin to teleporting. Through mysterious means, he enchants the strength in his legs, distorting space to strike them so hard that they would reappear opposite to his direction.
In Mortal Kombat 11, Rain now wields a jamadhar, a katar consisting of three blades with the middle blade being hidden by two retracting blades. His powers and the backstory behind most of them have been heavily expanded on as well. He now has the ability to open dimensional rifts into the previously unexplored water realm. This allows him to create two different kinds of portals: a portal made out of water and one that has a purple color with a yellowish outline. The latter is often used in combat to teleport opponents after being launched by an attack, but he can also use it as a deadly projectile as well as imbue his attacks with it. Even his hydrokinesis has been expanded, as he can now create deadly weapons out of highly pressurized water and even summon tidal waves to wash away his opponents. His ability to turn into water has also been expanded considerably, being able to reshape himself into an orb to snag his enemies into the air and slam them into the ground or shift into his liquid state to either slip past his opponents or allow attacks to pass through his form harmlessly.
- Mind Control Orb: Rain projects a light-blue sphere at his opponent, which shatters as it hits. A successful hit allows Rain to move his opponent's body in any direction for a brief time. In Mortal Kombat (2011), the move is now called Water Bubble and the opponent is encased within it. In MK11, the move is renamed to Water Ball, and Rain launches a small water orb that knocks the opponent down on hit. This ability replaces Katar Toss when equipped. (MKT, MK 2011, MKX)
- The enhanced version is called Hydro Bubble and it grants a meter drain while the opponent is encased in it.
- In MK11, amplifying the move expands the orb into a large bubble that encases the opponent within and pops, launching them in a direction Rain chooses. When launched downwards, the opponent bounces off the ground, allowing for a juggle.
- Shocking Bolt: Rain raises his arm and summons a blue lightning bolt to strike his enemy. This attack was borrowed by Nightwolf in Mortal Kombat: Deception. In Mortal Kombat (2011), it is called Lightning and the bolts are purple. (MKT, MK:A, MK 2011, MKX)
- The enhanced version is called Thunder Storm and it allows him to fire off three bolts in succession.
- Super Roundhouse: Rain reverse roundhouses his opponent clear to the other side of the screen. In Mortal Kombat (2011), it's called Super Kick and can be postponed. In MK11, Rain spins around and kicks the opponent through a portal, teleporting them to the other side. (MKT, MK 2011, MKX, MK11)
- The enhanced version is called Power Kick, it can be postponed and increases in damage.
- Water Blast: Rain shoots a high-pressure stream of water at his adversary, knocking the opponent down. In Mortal Kombat (2011), the move is named Aqua Splash. (MK:A, MK 2011)
- The enhanced version is called Aqua Blast, allowing Rain to shoot streams of water from both hands.
- Mystic Vapors: Rain submerges himself in a small pool of water and emerges behind his opponent. In Mortal Kombat (2011), the move is named Water-Port and can be done in the air. (MK:A, MK 2011, MKX)
- The enhanced version is called Aqua-Port which adds a Geyser Kick after the teleport.
- Windy Feet: Rain propels himself forward with a blast of water from behind, kicking his opponent in the chest with both feet. (MK:A)

- Geyser Kick: Rain twirls in the air before kicking his opponent away. (MK11)
- The amplified version causes Rain to kick his opponent into a rift and opening one behind him, to which they fall from.
- Katar Toss: Rain throws his Katar at the opponent. (MK11)
- Amplifying the move while the projectile is travelling turns it from a High attack into a Mid attack.
- Amplifying the move with the katar stuck in the opponent has Rain dislodge the weapon from his opponent, knocking them down.
- Argus Plunge: Rain forms a water sphere around himself and plunges towards the opponent. He grabs them, carries them, then slams them downing after traveling a certain distance. This attack has armor breaking properties, ignoring the armor granted by specific abilities and Fatal Blows. (MK11)
- The amplified version causes Rain to fly into the air with the opponent, then dive downwards head first, slamming the opponent.
- If Rain travels a full-screen distance during the move or breaks armor, the amplified version is turned into a Krushing Blow, where when Kabal slams the opponent, he shatters their ribs, dealing increased damage, and sending the opponent high in the air for a juggle.
- Evaporate: Rain turns his entire body into water, becoming invulnerable to any type of attack and allowing the opponent to phase through him. (MK11)
- Quantum Slice: Rain shoots a high pressure water stream that is imbued with a streak of energy. He can also perform the move mid-air, dashing forward or diagonally downwards with the energy streak. This ability replaces Argus Plunge when equipped. (MK11 - Equip Ability)
- Amplifying the move has Rain shoot out another stream, while amplifying it mid-air has his dash in the opposite direction or launch the opponent in the air with a streak, depending on the angle of the move.
- Quantum Rift: Rain creates a portal on the fightline that absorbs enemy projectiles and long-ranged attacks like Scorpion's Spear while active. This ability replaces Evaporate when equipped. (MK11 - Equip Ability)
- X-Ray - Rain Check: Rain conjures a geyser below the opponent, which lands them in front of him.

(MK 2011)
- Fatal Blow: Rain summons a waterspout from the ground that suspends the opponent before creating a downpour and delivering two spin kicks to their face and a backflip kick to launch them into the air. He then opens the blades of his katar and leaps after the opponent, impaling them through the abdomen and tossing them down to bounce off the ground. Rain finishes by creating water spears and piercing the opponent's chest and limbs with them. (MK11)
- Throw: Rain grabs his opponent in a bear hug, then launches himself into the air in a jet stream of water, and comes back down headfirst, slamming his opponent onto the ground just as Rain vanishes into a burst of water. (MK 2011, MKX)
- Throw (Forward): Rain stabs the opponent in the chest with his katar, blasts them with a high pressure water stream and finally kicks them away. (MK11)
- Throw (Backward): Rain becomes liquid and phases through the opponent before hooking their arm behind their back, stabbing them in the back through the hand with his katar and knocking them away with a tidal wave. (MK11)
- If Rain performs this on an opponent who has failed a Throw Escape during a previous Throw before, the attack turns into a Krushing Blow, where when Rain stabs the opponent in the back, the katar plunges deep and causes blood to spurt out, dealing increased damage.

- Eye-Solated: Rain creates a spinning discus out of water and sends it at the opponent where it cleaves their body horizontally in too before transforming into a high pressure geyser that tears their skin off of their front torso along with the eyes. Rain then uses the discus to slice the body into four parts and creates a water bubble in his hand with the opponent's eyes dropping into it. (MK11)

Played by Tyrone Cortez Wiggins, Rain made a brief appearance in Mortal Kombat: Annihilation. He was killed by Shao Kahn at a relatively early stage in the film due to not forcing Kabal and Kurtis Stryker to beg for their lives and not killing them. Enraged, Shao Kahn knocks him into a fire pit using his Wrath Hammer. This abrupt end, before any display of Rain's fighting or magical abilities, was seen by fans as an example of the film's inability to deal properly with a large number of characters introduced within its running time. It is implied that Rain was the general of Shao Kahn's extermination squads, ranking higher than Motaro, Sheeva, and Ermac, as all three contend to fill the role after Rain's death (a role eventually awarded to Sindel). This, however, contradicts Raiden's threat of killing all four of Kahn's "generals" at the start of the movie. Stock footage of Rain's demise is used for Baraka's death in a later scene.
Rain made an appearance during one episode of Mortal Kombat: Conquest, where he was played by Percy Brown. Shao Kahn sends him to kill Kung Lao so as to eliminate Earth's Grand Champion before the next tournament. Rain does battle with the monk, whom he is able to damage greatly, but Rain also becomes injured during the fight. As Kung Lao's friends arrive, Rain escapes in his weakened state. He appears later in the episode after being trailed by Siro. While the two are in combat, Kitana intervenes, forcing Rain to flee once again. Kitana then reveals that she and Rain were once 'close', but he had become seduced by the power offered by Shao Kahn and chose to betray his homeland of Edenia.
Rain has also appeared in an episode Skin Deep of the animated Mortal Kombat: Defenders of the Realm series. He was portrayed as Kitana's ex-fiance who was thought to have been killed in battle against Shao Kahn thousands of years ago, sparking jealousy in Liu Kang. However, Rain betrayed the heroes and kidnapped his former comrade, swearing allegiance to Shao Kahn as the emperor appreciated his talents. He went unmasked throughout this entire episode. It is also hinted that Rain was only engaged to Kitana simply because of her power as a princess.
- In Mortal Kombat: Defenders of the Realm, Rain was once engaged to Kitana, causing Liu Kang to become jealous whenever he made an appearance. Rain's former relationship with Kitana was also included in Mortal Kombat: Conquest. The relationship between them has never been hinted in the games.
- Rain's stationary pose changes between console versions of Mortal Kombat Trilogy. In the Nintendo 64 version, Rain uses the same "dragon claw" pose as Reptile, as he did in versions of Ultimate Mortal Kombat 3 where he was selectable. In every other version of MKT, however, Rain uses the "Scorpion Tail" pose used by every other male ninja (minus Reptile) featured in the game.
- One Kombat code activated the message: "Rain can be found in the graveyard."
- Rain's roundhouse kick sends the opponent flying off the screen and back on the other side. However, it only does about one-third as much damage as other kombatants' roundhouse kicks.
- Mortal Kombat Advance was the only port of Ultimate MK3 that gave Rain his own unique fatality (though the fatality was borrowed from MK Trilogy).
- His bio, before it was retconned, had him as an ex-member of the Lin Kuei who left to work for Shao Kahn, which was meant for Tremor before Rain replaced him.
- In Mortal Kombat: Armageddon, both of Rain's costumes depicts him carrying a dagger on his waistline. This could be a reference to Mortal Kombat: Deception's Konquest mode, where Shujinko finds and delivers a ceremonial dagger to Rain.
- In Mortal Kombat: Deception's Konquest mode, he retains his UMK3 appearance.
- Rain's Friendship in Mortal Kombat Advance may be a reference to Mary Poppins, as she can fly with an umbrella just as Rain did.
- In early versions of MK:A, Karate was supposed to be his unarmed fighting style.
- Further hints to Rain's concept designs that are based on the 80's pop song can be found in Mortal Kombat: Deception's Konquest mode after Jade succeeds in her ambush against Rain. When speaking to Jade, she will say "Purple? Rain chooses his wardrobe most curiously."
- In the fighting game Skullgirls Encore, the character Fukua has a color palette that is based on Rain's colors. This is one of her three color palettes referencing Mortal Kombat, the other two being Ermac and Reptile.
- Rain was considered to be on the Mortal Kombat X playable roster but didn't make the cut. Instead, he makes an appearance in the story mode as well as in the background of the Pit stage where he is seen fighting Blaze.
- He cameos in the mobile game when fighting Klassic Reptile in the background of The Pit, appearing as his UMK3 palette fighting a dark orange palette of Blaze.
- Rain, Stryker, Sheeva, Kintaro and Motaro did not appear in the series for 9 years (starting with MK4 to MKD). This is the largest period of time during which the character does not appear in the games of the series.
- Rain makes his return in Mortal Kombat 11 as part of the Kombat Pack 2 DLC. This also marks his second time he return as a DLC character, the first being in Mortal Kombat (2011).
- Before Kombat Pack 2, Rain makes three cameo appearances in MK11:
- Two of these are found in the Krypt; when crossing the bridge over the Pit, he can be seen fighting Blaze, much like in MKX. His other cameo occurs near the Pit, appearing as one of the other random ninjas that fall to their death.
- Shang Tsung uses Rain's likeness in his moveset; appearing in his Klassic costume and using his Super Roundhouse move.
- Kombat League had made Purple/Rain Themed skins for Kitana, Geras, Shao Kahn and Kuai Liang
