Wreckage (Energon)

Wreckage is an Autobot-allied Mini-Con in the Energon portion of the Unicron Trillogy.

Wreckage is a powerful mini-con who combines with his teammates to form an even more powerful weapon: The legendary Energon Saber. He and his teammates spent years embeded in Energon deposits which apparently gifted them with the ability to form a blade composed primarily of the powerful element. Like his teammates, he considers being an individual important but has a high regard for teamwork as well. Some believe this team may hold the key to the ultimate defeat of Unicron.
