Tech Jacket Volume 1: The Boy From Earth

The Geldarians are a race of incredibly intelligent, yet physically weak and
fragile beings. To compensate for their frailty they have invented the Tech
Jacket, a vest that every Geldarian is equipped with upon birth. A fully
developed Tech Jacket is considered to be one of the most powerful weapons in
the universe. Zack Thompson, through an event of sheer chance, has come to
possess a Tech Jacket of his own. Now it appears that the fate of the entire
universe rests on his shoulders as he learns that with infinite power comes
infinite responsibility.
