He is a Tyrant, they all are, including the Nemesis. Read the above link in my post and check out all the Tyrants.
Hell, here is the main Tyrant link.

Models of Tyrant
Experimental Tyrants
T-001 - Released unintentionally, defeated by Rebecca Chambers and Billy Coen - killed by Wesker.
T-002 - Released by Wesker, killed by Chris Redfield, Jill Valentine, Barry Burton, and Rebecca Chambers.
091 - First t+G virus Tyrant, killed by Bruce McGivern.
T-011 - Experimental prototype of T-A.L.O.S.
Hypnos-T Type - Experimental Tyrant being created in order to establish a more ferocious series of Tyrants following the success of the T-103. Killed by Ark Thompson.
Bandersnatch - A offshoot variation of the tyrant developed on Rockfort Island and released early to kill claire Redfield.
Mass produced models and variants
T-103 - First mass-produced Tyrant. In Raccoon City, one was sent to retrieve the G-virus. The one that was sent to Raccoon City was killed by Leon S. Kennedy with the help of Ada Wong. Others were sent in to help Umbrella Security Services, and to fight off the United States Army Special Forces.
Tyrant C - Similar to the T-103 (only appears in a non-canon minigame).
Nemesis-T Type - A T-103 used to host the NE-α parasite and retain higher level intelligence, an off-shoot of the Tyrant project. It was sent into Raccoon City to hunt and kill all surviving S.T.A.R.S. members. Killed by Jill Valentine.
Tyrant (T-103 Mass Produced Type) - A T-103 variant released by Alfred Ashford and killed by Claire Redfield. Despite its name and the apparent clarification that "T-078" refers to its batch number, this Tyrant seems to have been an experimental model and only one has been seen so far.
Tyrant R - A variation of the T-103, was released by Carter, absorbed by Nyx, defeated by David King and killed by Ada Wong.
Ivan - Highly intelligent T-103 variant able to integrate better into human society. Both were killed by Albert Wesker.
T-A.L.O.S. - Heavily armoured Tyrant outfitted with cybernetics and machinery. Killed by Chris Redfield and Jill Valentine.
Thanatos - Created by Greg Mueller as a more effective, unique Tyrant.
Tyrant 013: A model of Tyrant with a strong resemblance to the T-103 model that appeared in the Eastern Slav civil war. Identified only by the presence of the numbers 013 on the shoulder of one Tyrant, presumably a batch or model number.
