Who says pairings need to be romantic? Plain ol' friendship can be just as powerful, if not more powerful. And one thing I really like about platonic pairings is that matters such as gender or, in this case, species, don't matter. It's all about compatibility on the friendship level.
Well, obviously my favorite is going to Tech and Rev. My 2nd favorite is probably Duck and Lexi... they have a lot of funny interactions together. For my 3rd choice I'm almost tempted to go with either Duck and Slam or even Tech and Zadavia.
I didn't put Ace and Lexi since I see those two as the only possible candidates for a non-platonic relationship, but that shouldn't stop anyone else.
I thought what you said was gonna be relationships that had more than 2 people in it. But it's just me. Glad you cleared that for me.
Anyways, for the topic, I do like Tech's and Rev's freindship. In fact, it has to be my favourite. Because before they were friends, the roadrunners and coyotes have had a bit of rivalry for years and here we see two guys who people say could be rivals aren't. I just love Rev being the cute, optimistic, childish one while Tech is the intelligent, mature and sensible one. Oppisites do attract you know.
I like Duck's and Lexi's relationship. They sort of bicker like brother and sister but when they work together, they make a good team.
