Alpha was one of the assassins hired by David Cain to train his daughter.
Cassandra Cain (Batgirl) an amazing martial artist to say in the least. Alpha fit right in on the League Of Assassins roster.
Years later Alpha was employed by terrorists to plant a fusion bomb in Gotham City but soon afterward was struck with amnesia, Batgirl then saved Alpha and explained to him that he was a secret agent named Micheal Sommers. The two then search for a arms shipment. Once they find it Batgirl leaves Micheal alone, he is then jumped by five thugs. He has a flash back to a earlier fight and defeats the thugs single handedly.
Afterward Batgirl convinces him to help her find the bomb. Soon after finding the bomb Alpha's memory returned and he turned on her explaining that people like him "Cant Change" this influenced Batgirl to reveal her true identity to prove that people can change, Alpha locked her in the room with the bomb but changed his mind and ended up deactivating it from a distance.
Member of The League
Again appearing in Batgirl's life Alpha was revealed to have joined the new League of Assassins led by Nyssa Al Ghul and Lady Shiva. He was recruited by Lady Shiva herself and served in their ranks. His specific function was to help
Mad Dog hone his skills. Shiva hoped to forge him into a fighter to rival herself and Cassandra. He had ulterior motives however, he planned to Kill David Cain's failed creation. In the resulting chaos of the story many league of assassins members were killed while battling Lazara's reanimated dead. When the League was split in two half following Shiva and the other Cassandra he watched from the shadows not picking any side just waiting for a time to kill
Mad Dog. When his time came however Cassandra stopped him and had him guard Tigris who was one of her followers who was injured fighting Mad Dog. When Cassandra was killed saving them from Mad Dog he tried to stop Shiva from resurrecting her but Shiva defeated him.
Him and Tigris disappeared together, its unknown if he killed an unconscious Mad Dog. He has recently appeared alive alongside Mad Dog and other members of the League. He is present at the Grimm Brother's funeral, and is one of the many assassins to take part in a battle with Batman Incorporated.
Skills and Abilities
Alpha is a world class martial artist who was trained conventionally in the use
of blades. As time went on he was trained in the use of Firearms. He combined the two and became the consummate Gun Fu expert of the D.C universe. He is cabaple of maintaining a fight with guns in both hands. He can spar with an opponent armed with swords knives or more conventional weapons with ease. Also of note is that his skill is notable enough for David Cain and Lady Shiva to recruit him into the league of assassins. His beauty in combat and how his moves flow is also something noted by Lady shiva.
Despite not having the raw skill of Mad Dog or Cassandra Cain he was able to train both and spar with them easily even without the aid of guns.
