Halfshell leads the Space Pirate Seacon band in their quest for treasure across the cosmos. His primary goal: money. Secondary goal: money. Shrewd and calculating, he looks at everything in relation to how he can profit monetarily from it or how much something will end up costing him. While many expect that this would make him a cold-sparked sort who'd sell out his teammates for a big enough profit, nothing could be further from the truth. Halfshell takes friendship seriously and is downright generous towards his friends, be they Maximal or Predacon. And if you have Halfshell for a friend, you've got one big bruiser on your side.
