Escargon

Escargon is a Maximal in the Beast Era portion of the Generation 1 continuity.

"Involuntary gender-reassignment time!"

Escargon is, well... kinda creepy.

He spends most of his time curled up in his shell. But if he encounters a foe who catches his 'interest' he'll try to poke them with his Love-Love Lancer, which can change their gender.

Sweet, slow lovemaking follows, presumably.

(Note: Imaki Shouji created Escargon to show of what a submission to the Comic Bom-Bom Character Design Contest should look like, and did not actually appear in any fiction. The winner of the competition was Star Upper.)
