The Kaminoans hated clones that weren't perfect. If a clone cadet was bad at fighting, didn't look right, or was the weakest of their batchmates, the Kaminoans would decommission them. Clone cadet, Comet, was one of those clones. He wasn't as good at fighting, shooting, or as strong as his batchmates. He was the weakest one out of them. He always tried to prove the Kaminoans, his batchmates, and the bounty hunter trainers, that he was something more than a useless weak failure of a clone. It's hard for Comet because he's part of nothing, his batchmates hate him, but it all changes one day when he becomes part of the Wolfpack.
