Link, just because. Vincent Valentine, because I become all fangirly about him... and I'm a guy. Zack Fair, because they ate his hair. Fawful, from the Mario & Luigi series, because he is the most quotable character of all time. Luigi, because he's better than Mario. GLaDOS, because I'm a potato.
Coco Bandicoot (Crash Bandicoot) Crash Bandicoot (Crash Bandicoot) Strider Hiryu (Strider) Bowser (Super Mario Bros.) Dr. Ivo "Eggman" Robotnik (Sonic the Hedgehog) Sonic the Hedgehog (Sonic the Hedgehog) Guile (Street Fighter) Kyle Hyde (Hotel Dusk: Room 215) Victor von Gerdenheim (Darkstalkers) Dr. Neo Cortex (Crash Bandicoot)
Those are probably my favorites, in that order from favorite to least favorite. There is an absolute laundry list of video game characters I am a great fan of (quite a few, like Sir Dan and Ridley, having been mentioned), those are simply the really really big ones.
You don't wanna mess with Kratos (God of War) O_O His anger and determination in destroying the gods/goddesses really what made to one of my favorites. Apart from this is Lara Croft or Vincent Valentine
Nathan Drake (Because of the epic animation and lovable personality breathed into him by the talented Nolan North) closely followed by Commander Shepard (For me atleast. He may have a rigid personality but whenever he responds to someone it feels like 'I' am replying rather a 3D character because of the epic script; the choice for words, the tone of voice, everything.)
Ridley from the Metroid series GLaDOS from the Portal series Andrew Ryan from BioShock Red from the Pokémon series Ezio Auditore da Firenze from the Assassin's Creed series HK-47 from Star Wars: Knights of the Old Republic Master Chief from the Halo series Damon Baird from the Gears of War series Garrus Vakarian from the Mass Effect series Haytham Kenway from Assassin's Creed III
I'm talkin' about Marathon, the games that eventually led to Halo... Cause that security officer is a badass with a shit load of weapons. Master Cheif can only carry two at a time, the security officer carries them all.
Dominic Santiago FTW!!! In fact... A vast majority of the Gears of war crew... (except for Jace... Jace IMO was the worst.)
Also Samus from Metroid!!!! Simply because I have fond childhood memories playing Metroid and she was pretty bad ass at the time (for seven year old me haha) She may not be quite the overpowered monstrosity hero but... CHILDHOOD IMAGINATION BEATS ALL!! *Rainbow gesture*
Also Isaac Clarke from the Dead Space games, because he is just an ordinary Joe who's life gets torn to shreds and he still manages the bad ass, without any training other than using engineering tools.
I honestly don't have a favorite character because every game I play fervently involves a spaceship only. Definitely none of the scrubs today. Chief is cool I guess, but he's pretty vanilla as far as heroes go.
