Ultra Trion

Ultra Trion is an Autobot from the Universe series.

Ultra Trion is among the scattered few Autobots left on an alternate Cybertron that has been ravaged by Megazarak. He watches over the hall of the Oracle, welcoming those seeking enlightenment.

Universe Comic (OTFCC 2004 Program)
Megazarak sought out the Oracle guarded by Ultra Trion in order to locate Base Sigma, the location of the last pocket of Autobot resistance on his Cybertron, which was presumably where the Matrix was also kept hidden. Only Ultra Trion stood in his way, but Megazarak swatted him to the floor easily. Ultra Trion attempted to destroy Megazarak with a missile hidden in his right shoulder armor, knowing he would not survive his encounter with Megazarak. But the Decepticon warlord simply stuffed the missile back into Trion, detonating it without taking a hint of damage. Ultra Trion was not so lucky. Not content with merely grievously wounding the ancient Autobot, Megazarak then turned his main cannon on Trion and finished the job.

But Trion had gotten one over on Megazarak after all; the Oracle was no longer in its chamber. Ultra Trion had bought the remaining Autobot resistance a little more time.
