Biogator

Biogator is a Grotto Beast from the Grotto Beasts trading card game and TV show. With 8 attack and 7 health, it can prove to be a devastating enemy, and it is usually best to deal with it in as few turns as possible. In the show, he was encountered in the 7th dubbed the "sewer episode" where Otto and Rob are stuck below Grottopolis after Schlotto and Grot Esquire betray them. During the middle of the episode Sludge single handedly takes down Biogator and he slithers away into the water. He makes one final appearance in the 11th episode when Grot Esquire sends him out again only to be defeated again when Dustbunny uses a cocoon and traps him.

Biology
In the Sewer Episode, he was shown to have impenetrable skin only vulnerable to subdermal attacks, therefore Sludge was able to seep in between his scales and absorb his moisture supply. The lack of moisture can be deadly to Biogator. Biogator is also a ferocious predator that usually feeds on small and weak Grotto Beasts but he can take down some of the most powerful beasts if needed. He uses a deadly aerosolized poison emitted by his mouth. The poison is made in the red glands that are found in its throat and are visible on the outside of its face.

Video Game
Biogator was slated to also be in the unproduced Grotto Beasts video game by Sega. The game was supposed to come out in late to mid 1998 but the show was such a failure that it was unproduced.
