Cuber

Cuber is an ally in BATTD2. He returns from BATTD, however in BATTD he only gave tips while in BATTD2 he is an actual ally. He can only be equipped to Finn, Jake, Princess Bubblegum, and Ice King (because they are the main characters of the original five graybles, excluding BMO). When equipped to them, he shows them graybles, making them attack 25% faster. He costs $900 to place.
