Zipintilchik

Zipintilchik, aka Zippy, aka Trippy Zippy. 

His body is soft and squishy, his insides are basically a jelly-goo, which he can rearrange, such as by giving himself more gut or to exaggeratedly puff his chest out. Odd slime pup! 

He has psychic powers. He holds a power gem within his "hair" that is the source of these powers, which was gifted to him as part of his induction to a team of dream warriors who defend people from their own dreams and fantasies. 

He's a nervous wreck, but is still protective of his sister, Pipinkiti aka Pippi. When he sees she is afraid, his own fears melt away. 

The most powerful move he has is to make someone think all of their thoughts - their feelings, their sensations, their memories, their worries, etc - at the same time, causing extreme mental stress and overload that can potentially kill. Because of this, he only does this in an emergency and only does it for as short a time as absolutely necessary, because the longer it goes on, the greater the risk of death.
