Barricade

Barricade was created 149,450 years ago in order to drive the Vrai out of the Matoran Universe along with Blackout, Starscream, Brawl and Bonecrusher. After this was accomplished, Starscream, Barricade, Brawl and Bonecrusher were placed in stasis pods. When Blackout created Darkmount, he took the pods with him, and later ordered Malygos to retrieve a crystal, hidden by the Great Beings on a distant planet, which would reawaken the Makuta. That happened. Then, Ynot, the Makuta Anima and The Fallen attacked. Barricade attacked Hokagetsu. For once, he gets to fight someone who isn't rubbish at hand-to-hand combat.

After the battle, Blackout ordered Barricade to release a cyber-virus on Gorlam Prime, despite his objections that it was not tested.

Barricade spent a lot of time not doing much after that, until he was sent to the Enterprise in order to extract the co-ordinates of Atlantis from its navigational computer.

After disappearing for a long time again, he fought D-Klak along with Rahn, and blew a hole in the alternate Klak's armour with a lightning plasma grenade.

Most recently, a certain troll turned into a tophat and ate Barricade. His current status is unknown, but he might be used as a hostage somewhere down the road.
