best onces are Sonya and Noob Saibot in my opinion. but i saw great AI fighters as Baraka or Kotal Kahn. my AI team is Sonya, Noob and Raiden (as he is my main). i dont play AI Battles anymore as they give only shit on winning such as gold and hearts. still miss some Skins and Gear, but its boring to watch 5 battles, even if i win them all, and dont get skins/gear, when there still are some to get...
for Towers of Time, on PC, i rarely use AI fighter, trying to do all with Raiden and Sub-Zero myself. at the begining of the MK11 launch i used Sonya for ToTs. but on Switch i use AI for Towers a lot, i am lame playing on Switch, its not like gamepad on PC/console. and i mostly play Switch MK11 in work, so let the AI do it :)
have one loadout of fighters for AI Battles, one loadout for single player AI, with different Augments and ability points.
