Quagmire

Quagmire is a small man who resides in the Island of Illusion. It's unclear if he lived there or was banished there by Rita Repulsa (as his fear of her would indicate). He originally assumed the Rangers were sent by her when Kimberly mentioned her name, but soon learns they didn't and helped them with riddles in regaining their confidence and escape before Rita blew up the island.

He manage to escape as well, via being inside Jason's head when Rita placed a stronger magic on him ("Dear oh dear, I sense some nasty magic here").

He is last seen as a DJ at the dance competition Zack participated.
