DHD if he was in P:M.
-DHD gets duck cancel, making him able to cancel his duck based attacks into specials
-Down tilt changed to combo starter, with knockback changed to upwards to follow with aerial attacks
-All aerials become faster and neutral aerial does multihit
-Down Special gives DHD his Double Jump if it has been lost
-Up Special nerfed in favor of combo-based metagame
-Up tilt ducks now meteor smash so DHD can continue his combos if the foe gets too far
-Side Special disc does less knockback and damage but gets rapid fire
-Neutral special can be charged
-Fair changed to doggy bite for comboz (despite fair being one of his best moves)
-biting moves power up nspec for no describable reason
-Dash attack is now a single hit
-any previous comboz that may or may not have been successful have been removed because of new comboz metagame
-taunt has been removed
-down special now features him leaping out of grass to make it "less predictable"
-Pounce now goes linear
-Sense final smashes aren't used in competitive smash, and DHD has one of the worst final smashes in the game, we did you all a favor, and now DHD doesn't even have a final smash. You're welcome
