Puanti

Puanti is a pointy, green planet which only appeared in S2. In A Total Mess, Again..., he took all the shape planets along with a normal planet spawned by Red and then he left. Later, in Superpower Testing, he returned and brought back all the shape planets, before leaving forever.

Trivia

 * Puanti destroyed an entire solar system because it would not give him planets, but it is unknown how he did that.
