Part of my GI Joe 'Alterverse' where anything and everything can happen! If you read the bios, they kinda make a story.
"The attack was sudden and destructive, our MOBAT tanks and Armadillos being tossed about like tin cans. That's when we saw what was doing the damage. It was a single soldier calling himself 'Gutsman'. After a long battle Rock and Protoman were able to drive him into a retreat. We later learned that Zartan had stolen our plans so that Cobra could create dimensional gateways too. Beings known as Repliods were joining their side under control of a mad doctor that Cobra Commander had formed an alliance with...some fellow named Wiley."
