Tyler befriends Cody, due to finding similarities with Harold in him, and also like Harold, defending him whenever some of the tougher players like Duncan try to mess with him.

I guess I'll go with Trent as a rival, since The Am-AH-Zon Race shows that Tyler supports the idea of Cody getting with Gwen, so I imagine he'd try to get the competition out ASAP, to try and help his new friend get his dream girl.
