Crusher

Crusher is a blue-ringed octopus. While they are a venomous variant of Octolings, Crusher is still a kind person and only uses their tetrodotoxin in self defense. Because of their toxin, Crusher has dyed their hair to seem nonthreatening and hide their rings. They do not like the idea of using their venom for violent purposes. Once Crusher makes their journey to the surface, they quickly make friends with Doctor Nicole "Nex" Meduso. They bond quickly over their shared trait of being venomous. Crusher works with Doctor Meduso to find an antidote for blue ring octopus venom.
