Probably the lead characters from Digimon Tamers. Even as a little kid I appreciated how well-rounded and realistic they were, despite a lot of the subtlety going over my head at the time. There's not much point in me going over why they're so fantastic myself, though, since someone already did a video series on them that's far more in-depth than any forum post I could ever write; on Takato [http://blip.tv/jesuotaku/digimon-tamers-part-two-takato-5918868], Henry [http://blip.tv/jesuotaku/digimon-tamers-part-two-henry-5919088], Rika [http://blip.tv/jesuotaku/digimon-tamers-part-two-rika-5965886], and Jeri [http://blip.tv/jesuotaku/digimon-tamers-part-two-jeri-5966097].
