In real life monkeys are also not running around wearing suits and wielding sub machine guns shooting at ducks driving giant walking machines.but here we are.
go and look up the height of sentinel.....sentinel is smaller than in comic lore due to gameplay issues....same goes for a few others but not as big of a degree.....if champs are too small it causes issues with hit boxes and other champs animations are uinable to hit them properly. this is the reason why rocket is flying. if he was standing on the ground most animations would miss/make contact with him in weird ways. also why he has a unique special 3.so if they made Hit Monkey half the size that he currently is in game other champs hits would be failing to make contact with him. he had to be made the way he is for game play and technical reasons.
There is no page of Hit-Monkey (Earth-TRN517)
But weren’t champions of the contest plucked up from different universes?
