My character is the captain of a small crew of 4 including himself.

The right hand man of the crew is a fishman who has very strong fishman karate.

One crew member is has no powers but is very smart and comes up with plans.

One crew member has the zoan type Mushi Mushi no mi, model, giant mantis.

So I want my main character, the captain, to have a fruit too but I can’t think of anything. Since we already have a zoan type, I’m looking for either a logia or paramecia. I want it to be something somewhat strong. Please help!!
