Deku (Ch202) we can be sure, he has two conditions called HAKKEI (Fa Jin) and TRANS_MISSION (Gearshift) and if you set an animation to use Ch202's skeleton it still fits Deku perfectly, plus there's effects and textures in the game that look perfect for Gearshift and Fa Jin.
the confusion was caused because All Might (Ch200) has these: Ch200Unique1_Ice and Ch200Unique1_Fire, Unique1 means Alpha and with fire and ice we kinda just assumed, AFO (Ch201) also had reference to an explosion so from the there we just jumped to the conclusion it was the main trio.
However doing some digging into the skeleton the characters in this game use we found bones for a wing like appendage for AFO called "Tyranthorn" which very much matches pic related
For All Might he has bones called "shooterarm"s which seem setup to pop out of his wrists, and "footarmor", and Armored AM's whole thing is that he uses moves that mimic 1-A's quirks so it's not weird for him to have fire and ice.
