When I was a kid the redeads from OoT scared the living(or dead)crap out of me as well as the skeleton kids from hyrule field.
Both scared me so bad as a kid I didn't play OoT for
years. Even today I don't feel safe til I've got the Sun's Song (and remember what you had to sneak past to get to it!).
(There's definitely a good feeling shooting those buggers in Twilight Princess with your bomb arrows. allllrighhht.)
For some reason, the bandits in the Paper Mario series always scare me as well (they come at you so fast, especially in the Dry Dry Desert - good for creating a 'dangerous desert' mood, bad for exploring the awesome place). It's kind of cool that you can talk to some of them in the second game, but I always keep my hammer at the ready when around them....
Voldo doesn't scare me - he just creeps me the hell out (have you seen his Xenomorph costume? Seriously fucked up, that one is). He's fun to beat the living crap out of, though.
