The Thunder Eraser (雷 ゴム, Kaminari Gomu) is an energy wave used by Super No. 17. Super No. 17 moves sideways very close to his opponent as he charges a purple and black energy sphere on his hand. He then fires small yellow energy waves out of the energy sphere point blank against the opponent, inflicting a great amount of damage.
