This matchup is obvious. I lol @ anyone saying this is even. This is an easy counter for Lucario, because if you are getting KO'd by a Peach before 150%, you are playing Lucario horribly wrong. Idk about you guys, but I find it easy to just punish Peach with a shield to reverse Utilt whenever she tries to float me. Generally, Peach is easy to toss around in this matchup and the only killing moves she has are Usmash, Fair, (when you're high enough) Nair and Dair, and gimping you. Gimping shouldn't ever reasonably happen unless there is a large gap of skill between you and the player, and with such little options, a lot of Peach players become predictable and easy to punish. If you can't beat up an average level Peach, you just suck horribly with Lucario.
If you know how to DI and punish, this match is just a test of how well you play Lucario. /matchup
By the way, we seriously need to go over some other matchups like DDD and DK imo, they are usually the biggest threats and easily counter Lucario. Some more coverage on tough matchups like Marth and Diddy would probably be best too. I don't think we should even bother with matchups like Luigi and Zelda until we handle the larger threats, because not only will you have a 95% chance to go against any given S or A tier character, but a good portion of them are what keep Lucario from having the best matchups. No one else counters him (except DK imo) that is outside of top tier, so the matchups are just intuitive. Focus on the cleaning up the **** that's thrown at us, not just completing for completion's sake. And Snake is easy unless the user is pro level, what the crap guys?
Edit: After reading for a single minute, someone who said Peach is even with Lucario was also approaching with Lucario. Fuh-****ing-ail.
