Bounty Hunter's Pet

Jack had seen many strange things. But finding a dying mech he'd never seen before in a forest? That was new. Jack, not one to turn a blind eye on someone in need, helps the mech, even taking energon from the 'bots secret emergency stores for the mech. He figured once the mech was better, he'd leave. Instead, he's kidnapped by the mech, known as the feared bounty hunter, Lockdown.
