Favorite Video Game Sidekick

Searched, no thread for this. Anyways sidekicks. Almost every video game hero has one. Sonic has Tails, Ratchet has Clank, Jak has Daxter, etc. But which ones are your favorite? Personally one of my favorites is Daxter. He is Jak's loyal squirrel or ferret or whatever he is. Daxter is hilarious, he always is funny to watch. He also got his own GAME where he had to find Jak after he was taken away at the beginning of Jak 2. But all that is just my opinion. Post your favorites below.
MegaMan's MegaBuster.
