Side-effects Of The Fusion State

Grey was not surprised at Bill's reactions, most geniuses who practice an odd method of fighting tend to be more excited when they see someone like them. In this case, even though Bill seemed to hate him, he couldn't hide the joy on his face after they exchanged blows some time ago. 

"If you say so, I won't hold back any longer." Grey said before charging at Bill. 

Just as he was about to arrive in front of Bill, he vanished and appeared on his left side as he threw a punch at him. 

Bill didn't expect Grey to use a method like this, but he still blocked the attack, but was pushed back. 

Grey attacked once again, his fist exploding with fire. 

Bill threw a punch of his own, his hand covered with lightning. Both fists collided and sparks flew everywhere.
