Caboose will try and join the Careers. He believes that he has a better chance of making it far with them.

As for getting in, he'll show off his pure strength, ripping apart dummies with his bare hands. If he can lift a bomb (in the canon universe he's from) that genetically enhanced people can't, he can easily do that. He'll try and be kind, but rough, and not be afraid to shove someone off. He has a good heart, but he can't show it or he may not get in.
