One change that I am super thrilled about is the Wii U version remembers the last name you used across all modes. That's so convenient.
FINALLY.
-The X and Proto Man costumes are only for Mii Gunners. That's a downer for me cause I only really like the Brawler.
Well, their helmets go on any Mii, at least. But yeah, it's the same deal as the in-game stuff: Clothes are class-specific, headgear is for any.
Loving Mewtwo. His moves may be the same but the rebalancing does take a little getting used to.
The bad:
-Shadow Ball no longer damages while charging. Makes Mewtwo less of a giant-killer.
-As far as I've noticed, reverse throw doesn't damage enemies around you anymore.
-Forward air doesn't have as much "oomph" to it, but the range is quite a bit wider.
-Disable is still pretty useless.
-Palutena's Guidance for him is the generic "I have no data on this fighter" that was hacked a while back, so it seems that's all we have to look forward to with other DLC characters.
The good:
-HE WORKS ONLINE, in case anyone was wondering.
-The extra finisher to his standard combo helps a LOT.
-Smash attacks are extremely powerful with solid range, especially the Up Smash.
-Dashing attack is MUCH stronger.
-Forward throw is much more consistent.
-Back and down arials are faster, and down got an extra darkness effect.
-Confusion is DEFINITELY improved. Faster, easier to work with, and tosses your opponent just long enough to set up a forward Smash if they don't jump/dodge just right.
-Up throw is still as solid as ever.
