Black the Corrupt : The one and only Imposter on the ship and everyone knows! However, he's kept around because he's nicer than he looks... when he doesn't use his many abilities such as toxic gas, poison, hypnosis, vampirism, binding and more to turn the other crewmates into his servants, eventually turning them into the Corrupt's meal or even unbirthing them into his child for a while~ (All of this should sound familiar to those who know about an old Pokemon game featuring all of this...~)

Yellow the Mini : Don't confuse him for a child, he's simply a tiny adult, cheerful and wholesome at all time! He doesn't mind it when the others make fun of his little stature and actually sorta look forward to new jokes they can come up with~
