The Weld of Truce

The Weld of Truce is an ancient Cybertronian artifact that can only be used by both an Autobot and Decepticon in rare times of desperation for a mutual situation. It has the power to temporarily fuse one Autobot and one Decepticon into a singular Transformer in order to get through a catastrophe they cannot accomplish on their own.
