Laast The Vindictive

Laast is the only survivor of a terrible accident. It was all caused by a screwdriver dropped by one of NASA's astronauts. It then floated through space and got into engines of an alien ship. Laast was saved by passing by vessel, nurtured back to health. He then swore he will avenge his people. Now he terrorize human space explorers, making trophies out of their helmets and sew lovely patchwork blanket from their mission patches.
