Boone/Dogmeat (Fallout)
Kicking off our list at number five is a double bundle of Fallout. On one hand we have Boone, expert marksman and former NCR Sharpshooter. Troubled by the events of his past, Boone will stop at nothing to show his hatred towards the Legion, normally in the form of a miserable depressing comment – seriously, this guy smiles less than Kanye. On the other hand we have Dogmeat. He's a dog, man's best friend... I don't think I need to say any more on that.
Weighted Companion Cube (Portal)
An odd choice as a sidekick. Here, we have a cube... a cube that doesn't talk, have feelings or emotions and constantly insists that you carry it around wherever you go. Yet, in a world full of tests set up to kill you, Companion Cube is your only friend. But, if that isn't enough to win you over, then maybe you should just take a second to consider the level of sacrifice that the cube takes in order for you to win the game. Spoiler warning: you have to throw it into a furnace, it's all very sad!
Yoshi (Mario Bros.)
It's hard to stomach the life of a sidekick, always being out of the spotlight, normally putting in the same level of effort as the "hero" and only getting half the credit. But for Yoshi, it's even worse: not only is he the sidekick to Mario, but also to Luigi, and with Luigi being almost a sidekick to Mario, does that not make Yoshi a sidekick's sidekick? Number 3 today is everyone's favourite little green dinosaur, with the ability to practically make Mario invincible and eat his foes.
Miles "Tails" Prower (Sonic the Hedgehog)
Life as Tails the Fox must be a tough one... Sonic the Hedgehog always steals the show, yet Tails is there through the thick and thin of it. Tails the Fox is Sonic's best friend, but he's also more than that. To us, Tails was one of the first available characters to nullify the horrific idea of taking turns when it came to gaming. Player two would take the role of Tails when he first appeared in Sonic the Hedgehog 2 and suddenly sidekicks had a voice. But for Tails, life has always been as a side kick - even his full name of 'Miles Prower' is a pun in reference to Sonic's immense speed. For those taking a while to see it, 'Miles Per Hour'?
Clank (Ratchet and Clank)
If Ratchet was the Brawn, then Clank was definitely the brain. Clank was the loveable robot equivalent of Inspector Gadget. From Jetpacks to Robowings, Clank was there to assist you in all the ways your Lombax body just wouldn't serve you. Originally, Clank was meant to be a brutal murderous robot, programmed to serve the notorious Chairman Drek. Fortunately for you though, Clank came out of the production line smaller and weaker than his fellow evil robot brethren. Being the "runt of the litter" makes him perfect to fill the role of "unlikeliest robot to save the day" and therefore puts him at number 1 on this list.
