Alfa

Alfa (Alpha), true name Jack Garvey, is the leader of the Element Network's international anti-terrorism special forces unit, The Wall.

Personality
Alfa is a rather stoic person of the "mission first, everything else second" mentality.

Special Chapter: The Wall
In the special chapter, Alfa briefs his team on a slavery ring that has abducted three children, two girls and one boy, for organ harvesting. He and Papa bust the children from their cell, and since their safety packs can only hold two kids, the boy decides to run with them. While suppressing the rest of the slavery ring and making their escape, they encounter two men that had beaten the boy earlier.

Noticing the boy's trembling, Alfa asks if they were the ones who beat him, rage evident on his face. When the boy nods silently, Alfa runs behind the men and overpowers them. Then&mdash;in breach of protocol&mdash;he draws out his gun with live ammunition and shoots them through the arms and legs before leaving with Papa and the children.

After reuniting the boy with his mother, Alfa watches from his car with a smile. As they start to drive away, Papa chides Alfa for breaking the team's rules. He disaffectedly responds, "You're right... Better think of a proper punishment."

Epilogue
Alfa is among those who attends Haruka and Mamoru's small wedding.

Abilities
Alpha has had military training in the U.S Army, the British SAS and numerous other world military outlets. In addition to this he was also a member of CIFA. He has received medals for missions that he has led, proving that he is a highly proficient leader.

The Wall
Alfa holds a deep bond with his subordinates, and places a great amount of trust in their ability to make decisions without his input.

Mamoru Hijikata
Alfa and Mamoru are quite alike in their view of combat and tactical decisions, leading to a great deal of mutual respect and trust. While Teppei Genda's warning that Mamoru is a killer puts him on alert, he tells Serena that whether or not it is true, Mamoru is currently on their side.

Haruka Tooyama
While he and Haruka don't have quite as much interaction with each other, he is vocally disgusted by the way she has been targeted for experimentation. At the end of the series, he is among those selected to attend her and Mamoru's wedding while the rest of The Wall (besides Juliet) stayed outside as guards.
