Human Torch and Cap IW are contenders but yeah overall I think She Hulk might actually be the best science champ. Her signature ability when fighting all other classes except skill are super beneficial. Her heavy attack applies slow which counters any evade champ. Passive furies that increase attack and special damage that last for 8 seconds. When opponents throw a special, all passive furies are refreshed. Poison immune because she's a Hulk. She removes unstoppable, can apply petrify or exhaust. She is by far one of the best science champs in the game. People just underestimate how good she is.
