Personality
Even though, Black Sponge is a rough and tough ninja he is also very passionate. He's very kind and giving but when someone gets on his nerves he's always free to do a quick ninja move on them. He feels more free as Black Sponge as Leader Plankton does not know who he is and he has no power as Prisoner SpongeBob.
