I guess, also charisma? Really? They have serious and authoritative personalities, nothing about them makes them fun-loving to other characters and people.
Maybe it’s not charisma, but they have the ability to gain the loyalty of others and maintain it when leading them. Fujin is more understanding to mortals than Raiden was according to MK11 Aftermath.
Scorpion as the leader for amazing leadership over the Shirai Ryu and Kenshi because he’s his best friend and is also good at commanding troops. Like in MKX along with the Special Forces.
Not offensive. Just haven’t seen that more than seeing the strongest beings being the leaders of any factions or groups. Except for the part when I know that Lex Luthor had led the Legion of Doom after Gorilla Grodd.
