The Giga Gargantuar has a near identical attack of the Gargantuar. Like the Gargantuar, he will attempt to smash plants with his telephone pole if they are near him. However, the Giga Gargantuar has some new moves and a health buff. He can use his telephone pole to fire an electricity laser which deals high damage if the player has not taken cover. He is also now able to shoot three explosive Imps, rather than one making it extremely more lethal than before. However, he does not have the charge attack the Gargantuar has. Like the Gargantuar, they cannot be swallowed or frozen, but they are vulnerable to the Chompers' Goop.
