Ravenator

Ravenator (voiced by Brad Orchard) was a monster who was mostly mouth and had a seemingly insatiable appetite for destruction.

He was created by Finster and used by Rita Repulsa and Lord Zedd. Ravenator was shrunk and ingested by Tommy Oliver, forcing him to eat to no end. He escaped Tommy's mouth when he resisted eating more and was destroyed by the Shogun Megazord.
