Titus

One of greatest enemies to Guardians of the Galaxy from Earth-TRN123. Fought against Spider-Man when he was helping Nova and other Guardians.

As a Supernova
Titus was a member of the Supernovas, a branch of the Nova Corps. He served with Jesse Alexander, the father of Sam Alexander, Mister Z'zz, The Phlish, and a few other supernovas. Following the dissertion of Jesse Alexander, Titus was attacked by the Chitauri, which lead to the loss of Titus' right eye and arm. After serving the Chitauri for several years, Titus came to Earth in search of Jesse Alexander's Nova helmet.

With the Chitauri
Titus lies to Sam telling him that he had killed his father however this is not true because Jesse Alexander is being held captive by the Chitauri When Titus finds Sam he threatens not only him, but everything he holds dearly to him in exchange for the Ultimate Nullifier he stole from their ship. Sam then gets back his helmet from Titus and takes them both to outer space, expecting the lack of oxygen to kill Titus. When that plan fails Sam takes out the Ultimate Nullifier and tells Titus to take his forces and leave. Titus and Sam then struggle for the gun and Sam accidentally triggers it killing Titus and an entire fleet of Chitauri.

Abilities
Able to breathe in outer space.
