Well, I was originally going to vent here, but I got inspiration after watching a YouTube video to do something less simultaneously migraine-inducing and controversial. I'll just discuss some of my favorite characters to play as in video game history, and why I enjoy them so much. The only rules here are one per game. These are not in order.

• Barik (Paladins)- The Dwarven god among men himself. My main when I played Paladins, he brought me so much enjoyment playing the game that I can hardly contain myself right now with the literal nostalgia I have on the topic. I actually don't know why I enjoy him so much. Maybe it's my signature playstyle of plopping turrets wherever I see fit and destroying everyone? Maybe it's his emphasis on positioning? Maybe it's dashing in circles like a little madman high on drugs? Maybe it's even because I'm playing as the Paladins equivalent of Goldeneye 007's Oddjob? I really don't know. But he's so enjoyable that I managed to play as him in over HALF of all of my matches playing the game.
• Axton (Borderlands 2)- My recent obsession, Axton has become my favorite Borderlands 2 character to play as. Why? Only one line must be said here. "Have you met the misses?" Are you starting to see a pattern here? Turrets. I freaking like turrets. Axton's turret has great offensive zoning potential building an Engineer build, and it also gives you INSANE buffs to your damage output running the Battlefront skill. Combining this with weapons with high damage potential like the Unkempt Harold results in the DPS being taken to MAXIMUM overdrive. Sure, he has the worst melee in the ENTIRE GAME and I like playing melee builds, but his turret build is even better than Melee Zer0 for me. 
• Yoshi (Smash Bros)- Oh. My. Word. The. SPIKES. I've always found Yoshi a blast to play because there's just so many ways you can burst your opponent into submission. But the most fun will always be spiking straight into volleyball combos. If you're unaware, Yoshi has the capability to pretend you're a volleyball and smack you into the next ZIP code with a combo of chaining down and up airs. They keep saying Villager isn't the face of mercy, but Yoshi is RUTHLESS. He'll knock you into the next ZIP code with his tail, He will throw eggs at your face like grenades. Heck, he will even use his HEAD as a weapon of mass destruction. Seriously, that noggin has some serious kill potential. 
• Sniper (Team Fortress 2)- There's a good reason he was my go-to when I played the game. He's a great example of how a sniper class should be executed. He's got a surprising amount of versatility, and he's got a lot of ranged damage. Sure it's at the expense of close-quarters... but... IT DOESN'T HAVE TO BE! Take a Shahanshah. Sure it deals bad damage if you melee somebody at above half health, but when you get flanked, it's super useful because your health pool is going to get low enough to get the damage buff at low health. With that boost, those annoying scouts are history. Also, he's even got support options! Get a Sydney Sleeper and you can mark targets for your team to take down for you!
• Mordecai (Borderlands 1)- Note that I didn't say one per SERIES. Sure, Bloodwing is a bit of a subpar action skill without investment, but that's more than made up for running him with a Sniper or a Pistol build. Sniper builds on him are BETTER than Zer0 in all honesty. With skills like Trespasser that allow you to have up to a 100% chance to IGNORE SHIELDS and skills like Killer that allow you to consistently chain damage output, it's not hard to see what makes him fun to play but also really good. This isn't to mention his potential with pistols (especially revolvers) running the right build, especially with the right Class Mods along with skills that buff reload speed and DPS.

I may add a League of Legends character and a DotA 2 character later on, but this is it.
