Powers: Halloran can transform into a large, elephantine-humanoid, with great strength (Class 25-75?) and durability. Apparently his intelligence began to degenerate sometime after his transformation, eventually leaving him as a bestial creature. As Mastodon, he has little control over his actions, and is a savage, cannibalistic creature. Mastodon retains some degree of Timothy's interests and memories.

History: (Exiles#1) - Timothy Halloran was a teenager living in San Diego with his single mother. Unbeknownst to him, he developed the Theta Virus, which made him a target sought by two people: Rachel Deming, who wished to help him, and Malcolm Kort, who wished to experiment on and learn from him. Deming and Kort each sent some of their agents to bring Halloran to him or her. Kort's agents overpowered Deming's and abducted Timothy--whose mother was killed during the struggle.

(Exiles#2) - Bloodbath brought Halloran to Kort's base, Visionary Productions, where Dr. Deeters began to attempt to control his powers. Halloran's powers were just beginning to surface, and Deeter's noted that he demonstrated the highest degree of virulence of the Theta Virus that he had ever seen. Deeters was unable to get control of the process and Halloran burst forth from the tank, full transformed into his Mastodon form, just as the Exiles (Deming's agents) arrived to rescue him.

(Exiles#3) - The Exiles tried to explain themselves to Halloran, but just like always, things degenerated into a brawl. Kort's agents came out and joined the fight, and Timothy took off as the two opposing forces battled. Deming and her Exiles tracked Halloran down, and after some more fighting, Deming nearly succeeded in convincing him of her intent. However, the sirens of incoming police made Halloran think she was just trying to stall him until the cops arrived, and so the fighting began anew. Halloran eventually escaped the Exiles, but the combination of the battle and a massive dose of tranquilizers took their toll, reverting him back to human form. His human form was much more severely affected by the tranks. As he staggered off, one of Kort's Cybernoids identified him and began to follow him.
