Here's a topic to post your top five favorite and most memorable characters from any video game you've played, from villain to hero, mascot to NPC, etc. So, I'll go first.
5th: Colonel (MMBN)
Even though I got Team Protoman, I love how sleek and awesome he is.
4th: Old Man (Pokemon Red/Blue)
He taught me everything I knew. Also, he's SO pro, he can catch a wild Pokemon without weakening it~
3rd: Phoenix Wright (Ace Attorney)
Carefree and serious at the same time, and I love how wacky he and his games are
2nd: Cloud Strife (Final Fantasy VII)
He was emo before it was cool.
I love how gigantic his sword is and the way he keeps his cool no matter what situation he's in,
Plus, he has a motorcycle. Can't really beat that. One of the most human video-game protagonists, imo. Also, he was one of the reasons I found Kingdom Hearts in the first place.
1st: Sora (Kingdom Hearts)
Who didn't see this comingFavorite all-time video-game character, mainly because how much I identify with his personality. Perfect combo of seriousness, lightheartedness, and style.
Honorable mentions to: Sonic, Tidus (Final Fantasy X), Sephiroth (Final Fantasy VII), Megaman Zero, and so many other RPG heroes.
So yeah, be creative, and have fun!
