Top 10 Best Video Game Rivals and Companions
A rival exists to show you where you need to improve in your gaming skills when you lose. A companion, on the other hand, is there to help you along the way. While some games don't have either, there are plenty of games to choose from.Please enjoy and vote for your favorite!
A little brother to him, Luigi is his sidekick and helps him out a lot. I'm not a super fan, but I know that he's helpful and is a coward too, but Mario is always there to save him, most of the time.
Mysterious, strong, and a badass trainer, Silver is like Blue, who never had a chance next to this guy. He treats Pokemon as tools but is less understandable. He gets more involved with Team Rocket, his father's organization, than Blue does.
He still kept his personality in the remakes, unlike Blue, and has been in a more recent game than him, last appearing in the main story plot in 2010, rather than 2004. The world tournaments don't count.
He's the exact opposite of Sonic, being smart, and focusing more on strategy than outspeeding the opponent. He's like a little brother to Sonic, and I really enjoy that feeling, like he's always there for you.
I would classify this guy as a rival since he doesn't help you a lot other than in Mega Man 3, as far as I know. He is the prototype of you, and he's supposedly stronger than you. He's also mysterious and has a dead past, but he joined the bad guys once, instead of being related to them.
The reason I put these three here is because they are very similar in design and use.
Donkey Kong Country is a different series from Mario, so it gets its little place on here. Also, I'm running out of ideas here. He's your son, and that's all I know about him. Also, that old cranky monkey, he's the original, and the tie-wearing Donkey Kong is the baby in Donkey Kong 2, sequel to the original.
What? I said only one or two per series. Well, this is the second one. He's your identical hedgehog with a different personality, seeing the guns and curse words in the game, Shadow the Hedgehog, named after him. He's suffering from amnesia, and when he steals the Chaos Emeralds, you're blamed. I was planning to put Knuckles here, but hey, I know more about this guy.
This character is unique because you play as him in one series, and then you rival him in another. He's the anti-you, you being helpful and selfless, while he's fat, lazy, and selfish, loving money and food.
Being the prequel to the Mario series, but released after it, you play as Yoshi to protect Baby Mario from Baby Bowser's wrath. There are multiple Yoshis that help you along the way.

The rivalry between sons of Sparda is one of the best in video game history. His quest for power (to protect what he values most) is the main plot that leads to all events in DMC3. As Dante grows stronger, he also grows. Their final showdown is one of the greatest showdowns I have ever encountered.
The Newcomers
Can it wait for a bit? I'm in the middle of some calibrations.
Unlike Silver, this girl is kind and sweet, and later comes to be Professor Juniper's assistant. She sucks at battling, but instead of trying to become stronger, like Hugh, Blue, Calem, Cheren, Silver, and all those older rivals, May is the same thing, except she could be in love with you...

The rival of Sora, until the end, where they become one.
