Big-hearted and blissfully unaware of his own strength, Coop is a loyal wrecking ball whose affection often arrives at dangerous speeds. Transformed by the Atomic Heart Engine, his size and power increased—but his gentle, devoted nature never changed.
In the chaos following the explosion at Sunrise Sanctuary, Coop became both protector and unintended force of destruction. Fiercely loyal to those he cares about, he represents unshakable friendship, raw power, and the unpredictable consequences of mutation within the Atomic Critters universe.
