Max Ooze inflicts damage and then raises the user's and its ally's Special Attack by one stage. Its power and whether it is a special or physical move depends on the move it is based on. Compared to the other Max Moves, it usually has less power.
Gigantamax Gengar releases a wave of purple sludge from its body at the opponent. It can also manipulate the sludge, sending streams of purple poison to attack the opponent.
