Every hero needs a sidekick, so we have gone thou the best and named the ones that deserve the title 'Partners in Crime'!
Mass Effect - the greatest bro in gaming. Loyal, funny and just all round badass Turian who is obsessed with calibrations!
Final Fantasy 13-2 - he was your main weapon, he was able to help locate items, you could throw him to get ditant or out of reach items and chests and he had some decent spots of dialogue too.
Super Mario Bros - A cute and faithful pet plus he saves Mario walking everywhere.
Resident Evil - Ok we don't know if she's actually good or bad or who she's working for, but she's probably the most skilled character in the series and Leon loves her so I do too.
Metal Gear Solid - Not only is he useful, he and Snake have some moments together (and intelligent conversations about life). Plus you get to like him as character that you don't mind help save his Sister in 2. Plus I had a feeling he has a slight hero crush on Snake, clutching him a bit tightly on the back of the bike at the end of the first MGS.
Beyond: Two Souls - Just how cool would it be to have a sprit watching over you. Defecting bullets and saving your life.
Kane & Lynch - Sure he's the main character in the second game but he's
just too cute not to pick.
Fallout: Las Vegas - He was my bro anyway.
COD4: Modern Warfare - "I like to keep this for close encounters". Sparked rumours that he may have been Ghost from MW2, either way he was one badass you wanted fighting on your side.
Zelda - She may be annoying sometimes but still helps you out.
Infamous - Despite a brief lack of faith in the first Infamous, Zeke was been with Cole thou thick and thin. Always there as a friend and saviour. Even when at deaths door.
Moonwalker - I'd say best duo in a game is Jacko and bubbles I mean come on who wouldn't want a chimp atop their head pointing directions, shamon!
