While I am not a huge fan of sidekicks in general every once in a while a shining brilliant example of one comes to the forefront and really helps his hero out. As a huge Mario fan I would figure that Yoshi would be my favorite sidekick but I have never cared for Yoshi (even though my kids LOVE him!). As much as I dislike Sonic I have always been fond of Tails and he has been my default go to guy since he debuted back in Sonic 2 on the Sega Genesis. Chocobo might have given him a run for his money but I think of Chocobos more as mascots then proper sidekicks.
Well, I think Tails has finally been dethroned. I have been playing through a game called Rhythm Thief & The Emperor's Treasure for the Nintendo 3DS and the protagonist, Phantom R, has a dog named Fondue who serves as his trusty sidekick. Fondue is as helpful as he is humorous, often biting those who set themselve up in opposition to Phantom R. Fondue reminds me of what a good sidekick can be.
Who is your favorite sidekick and why?
