Yeah, sorry for bumping this topic, I got a lot of them in one go to.... all Tekken. Also, these aren't as much of look-a-likes as they are comparisons on a personality level.
First, the most obvious:
Stella and Lili.
Hot, fashionable, blonde, royally spoiled brats? (Lili's the heiress of an oil tycoon, it counts.) Check. But more interestingly, they take a stereotype which I loathe (The 'Fashionista/Dumb blonde/spoiled brat one), and make it work. Why? Well, first off, both of these girls care a whole lot about their fathers (Stella's Enchantix sacrifice, Lili entering the tournament to help her father's company....) and others, and they can kick your behind every day of the week.
Riven and Jin:
Just.... look at that hair! Look at it! How much hair gel do these guys use? Also, these guys need to be taken down some pegs. They both treat the girls who love them badly (Ling/Musa who, co-incidentally, both are Asian and have pigtails), have a horribly emo attitude in general and need to get a serious slapping from someone. (Kazuya! Knock some sense into your boy!)
Alisa and Tecna:
Well, pink hair, purple color scheme.... and they both provide their group with the useful facts and logic. Only difference? I love Tecna, I LOATHE Alisa (Grow a personality!)
Okay.... the last one must come with a warning; these guys LOOK nothing alike, it's their personality that makes the comparison.
Gantlos and Bryan Fury
Yeah, like I said, looks nothing like him. However, their personalities are a very close match. Both are avatars of destruction. They both take a sadistic glee in just causing heaps of chaos, mayhem and destruction. They live for it, they
breathe it. Also, I think their laughs match. Dangerous and totally crazy, Earth probably wouldn't survive for long if these two tag-teamed.
