Lady Carina: Mantis shrimp due to them being able to punch so hard they can make cavitation bubbles
General Argos: Sword fish pretty self-explanatory
Lord Elius: I know he isn’t mutated right now but if he does get infected I’m guessing something like an electric eel to wrap around Carina
Tucker: Zombie salmon because I want modern to see him and have a panic attack
Captain Arwald: Octopus because he tricked us and Lord Ulricus and was able to run away with the money
General Julian: Sea salp because they can exist as a individual organism (One glass shard) or part of a larger organism (Multipule glass shards) and they are transparent
*Ruby roger: White eyes because it fulfils his dream of being king of the sea
