The Mercs by Jae Lee
Brutus by Tom McWeeney
A thug, a killer, a career criminal, Joey Parker found himself on Gamorra Island, alone and without a job. He easily dispatched three antagonists in a bar brawl there. Lord Kaizen, always on the lookout for promising raw materials, had him tested. When he was found to be a Seedling, Kaizen had him activated. After working for Kaizen and then freelancing, Brutus hooked up with the MERCs.
