All heroes of nerdy franchises become more powerful over time. They start out as rookies, then eventually become masters by training with a wise sensei or being corrupted by a cursed sword; you know the drill. The transformations are rarely realistic, but at least they offer some kind of explanation. Here's our tribute to six characters that got major upgrades for no apparent reason.

6. Claire Redfield (Resident Evil: Code Veronica)

Through Resident Evil 3, the main characters of the series were above-average survivors with a lucky streak. They had a slightly greater skillset than their idiot comrades and survived by utilizing teamwork and well-timed saves. Claire's first appearance in Resident Evil 2 painted her as the naïve, but tough, little sister of Chris Redfield. She was by no means a damsel in distress, but definitely wasn't outrunning helicopters or killing 50 armed guards with a single bullet. Until Code Veronica, that is.

And the trend didn't stop there. By later games, Leon was dodging lasers like a Matrix character and Chris looked like he'd been shooting horse steroids directly into his dick after every meal. And don't even get me started on Wesker. I miss Barry.

5. Mickey Mouse (Kingdom Hearts)

Even if you've never played a Mickey Mouse game, you can probably guess what they're like: Mickey Mouse capers and frolics across various fanciful levels, hopping on platforms, collecting trinkets and saving the day in the most family-friendly way possible. And that's where it would have ended were it not for the epic crossover that is Kingdom Hearts.

Under the guiding hand of Square Enix, Mickey became a cloak-wearing, keyblade-slinging badass, flipping around through the air and dealing brightly-colored magical death to wave after wave of Heartless. Until steamboats become radical again, expect this version of Mickey to be his most extreme form.

4. Yoda (Star Wars Prequels)

Just before his death in Return of the Jedi, Yoda was so feeble that he had to be carried around in a backpack. In the original trilogy, lightsaber fights were heavy with drama and integral to the plot. The prequels turned them into epic lightshow clusterfucks. Naturally, Lucas thought it wise to get Yoda in on the action. The once hobbled Jedi Master could now miraculously perform acrobatic feats that would put most superheroes to shame.

Yes, the prequels took place 20 years before the trilogy, but that amount of time is nothing to Yoda: He's 900 years-old in Return of the Jedi. To put it in human terms, that's like being able to do crazy double flips at age 83 and then being so old that you cease to exist at age 85. THAT IS NOT HOW AGING WORKS.
