25. Tripitaka and Monkey
Despite the fact that Monkey is pretty much forced to comply to Trip's demands by way of a device attached to his head that, upon Trip's death, will explode, it's nice to know the two are such good friends, even it is only because of the imminent threat of total annihilation. But when you throw out all the evidence of their abusive relationship, it's clear that the pair complements each other in many ways, considering how fantastically they work together. While Monkey tackles more physical legs of their tumultuous journey, Trip supports him with her extensive hacking prowess, even if she is a liability with her extremely limited combat abilities. She's kind of touchy though, so watch what you say about her -- you wouldn't want to die, or anything.
