I realize that we have alternative versions of the characters but i will take into account the stronger versions. Before list i will put my honorable mention that are the closest to the top 15.
-Johnny Cage
-Scorpion (Hanzo Hasashi)
-Goro
-Kung Lao
-Kenshi
Now the list
15. Kitana (Princess Kitana, Kitana Kahn)
As Princess of Edenia she's a daughter of Sindel which alone makes her powerful in MK11 thanks to her magic most likely inherited from her mother. Stronger than Jade, Mileena, Smoke, Baraka, Skarlet, Kollector even Johnny Cage and can even held her own against Shang Tsung and Shao Kahn which alone makes her powerful enough to everyone decided that she would rule Outworld.
14. D'Vorah (A treacherous Kytinn)
The hive mother is strong enough to kill and humiliate Mileena and Baraka without much effort she also beats Tanya and Demigod Rain. She can rival Kotal Kahn in power who is a Kahn and has God power and take on herself both Scorpion's and killed one of them. She's already one of characters than has highest kill count in 2nd timeline.
13. Kotal Kahn (Former Emperor of Outworld, Sun God)
Former Shao Kahn general, literally has sun and blood powers along with his totems which can gives him various abilities with he was always one step behind him but he still improves himself to be eventually rival of Shao Kahn to rule Outworld as he easily beats Kano and he will kill him if Tanya didn't help him later he beats Rain and Mileena he was also strong enough to struggle with power of amulet of Shinnok he also goes 1v2 against Jasqui and Takeda later he beats Baraka, Skarlet, Erron Black and stand a chance against Shao Kahn and he even managed to win one of their few fights.
12. Nightwolf (Grey Cloud, Shaman)
One of Raiden's strongest allies and second-in-command of his people can keep up with likes of Quan Chi beats Noob Saibot by throwing him into Soulnado, later he beats Cyrax and Sektor and helps Smoke and finally can keep up with Sindel who defeated the entire Raiden squad and even managed to defeat her by sacrificing herself even though he was weaker than her later he beats Kollector, Frost, his possessed self and possessed Sindel which i think they are weaker because they were resurrected by Quan Chi's magic and along with Shang Tsung and Fujin was able to beat Geras and together with the other two and Sindel they even beats Cetrion he would probably be the strongest Raiden ally if it weren't for Fujin.
11. Fujin (God of Wind, Former Protector of Earthrealm)
Possibly very close or even equal to Raiden since he's his younger brother and Wind God defending Earthrealm from Shinnok and the invading Netherrealm forces, along with Raiden he beat possessed Sindel, Stryker and Kabal (whom he also defeated in MK11) and Quan Chi himself. Later when he joined forces with Nightwolf, Shang Tsung they beat Geras together (although mainly for Nightwolf) and later he beats Noob and Jax Briggs who deceived by Kronika joined her, he also beats Sub-Zero and angry Raiden who didn't trust Shang Tsung at all and felt cheated. Fujin is also one of the three people on whom Kronika's magic did not work the other two are Shang Tsung and Raiden and with the help of Kronika crown and his allies he was even able to harm her. Fujin is indeed worthy of being called God.
Part 2 will include the remaining 10 characters.
