As briefly mentioned in his bio, Squiddy has the power to control tentacles, And no. he does not do what your about to say. (unless its with Aquata and with consent) Instead he uses them as a weapon, being able to wrap around an opponent at long range and snap their neck or flail them around like a whip, as well as make the ends razor sharp in order to create ballistic stabbing weapons. He is bar none, the strongest of the crew, and will almost never use the tentacles in order to let the rest of the crew have the fights and grow stronger , when pushed to the limit (in the finale of the first part) he is shown to be able to summon an entire kracken, with the tentacle's he uses being technically little portals, to wherever the kracken was held, in this moment he single handedly wipes out a fleet and smashes a ship in half.
he also chose his new pirate name as "squiddy" because on these powers, Which is rule 1 of what NOT TO DO WHEN TRYING TO GO ANONYMOUS!

(and if i do roleplay i never use those "god tier" attacks aside from long range stabbing and throwing stuff.
and i keep them limited to like, 3 points in the story, main characters's gotta have their special death power y'know? like Naruto's ninetails? yeah pretty much just go with that makes it easier to explain even though i hate comparing)
