Fusion was in a intense battle with Fusion, his other self. Fusion was going to set the Andoirds free, so Fusion had to stop him. Fusion pushed the button to set them free, but it turns out the button wasn't to set them free, it was to activate a nuclear explosion. Fusion pressed the button, and the nuclear explosion went off. One Fusion died, but the other one came out of the blast, but with an arm missing. Fusion took just a few steps and fainted onto the ground.
