Giant Caterpillar is one of the Super-Rare Units of the "Independent" faction in Metal Slug Attack. The Giant Caterpillar is the complete opposite of the Mini Caterpillar, where its attack damage, HP, production, etc. are much increased. The Giant Caterpillar's unit parts are available via Guild Shop or Event Crank. When placed with the Mini Caterpillar on the same deck, their AP cost is lowered by 10%, as a part of the deck called March of Caterpillar.
