DK has no tool against utilt.
comes out on frame 3. when he is behind us, you can only try to roll away...
it´s really even, maybe slight DK advantage,
because Fox can deal a lot of damage to DK but all his approaches are not
reliable at all, except dash sheild grab...he approaches with aerials that does not hav as much priority as your aerials, your uair should beat like everything, bair too...
when he is offstage try to gimp him with bair and hang on the edge, so he only can recover onto the stage, which is punishable...
you kill fox @ 80-90 % with punsh or fsmash,
you just have to watch out to not get hit by fair or dair, that deals a lot of damage...
Fox usually kills with upsmash (110% if fresh), dsmash (120?), or bair (110%)...
so watch out for this moves...
The thing against Fox is that you can´t play defensive bc he will damage your sheild,
and that the worst case scenario, bc Fox can rack up damage with dair and fair strings insane fast....
so never let your sheild become small...
I searched for openings with shine stalling, that worked ,
if someone predict that if you are running you will use grounded upB, he can space himself so that he can punishes you for that...
As DK I would go for bair approach, sometimes downB or ftilt...
Also if you see Fox running to you (what he does not have to do, bc of laers)
expect a aerial or a grab,
so the best way to counter this is bairs, sh in the high of his aerial, it will beat anything...
lately I find myself using way more bair combined with sh, fh and dj, more as a spacing move and defense, Its almost unpunishable, upB is punishable...
try to edgeguard Fox with some fairs, dairs and bairs maybe upBs....
Fox is vunerable when he recovers....
