Rocket is a sucker for an adventure. To the point where it's probably unhealthy. He also has a tendency to bring back beautiful things from his travels. Which would be alright, if it was just things. But he has a tendency to bring back beautiful Soquili as well. Rocket doesn't quite grasp the idea of sexual tension, so he's not getting that when he does that he leads others on almost mercilessly.
He does, however, love all of his "collection" equally. Of course, this causes even more friction among whomever he has collected, as they tend to vie for his attention with all they are. He doesn't seem to notice this, since he hardly even pays attention.
Actually, Rocket spends most of his time spacing out, which is partially why his name fits him so. If he's not hunting for beautiful things, then he's probably off in his head somewhere.
