A giant octopus and squid once endangered all the seafood (save squid and octopus) of port city Sardinia, before Cole Slawter caught them together and made them into individual dishes. Octopoison came from the takoyaki made with the body of the giant octopus. The dish made from the squid became Squid-Vicious.
Powers and abilities: Octopoison can smack things with its tentacles and shoots black ink shown to be corrosive enough to melt a boulder.
Based on: Takoyaki
