No. That is Chronos, the big one. The smol one is Squirrly's consciousness that Chronos is trying to destroy.

Squirrly stops him himself.

Squirrly turns into an angel basically and completely destroys Chronos. Not in the way you think, he doesn't erase him from existance. He just beats him enough for Chronos to switch sides and fight with Squirrly and the others.
