As you may have noticed, Diddy Kong has a slightly different Down-B animation this time around, and several players in my community have noted that it may actually be a bit slower than it was in the previous games. It seems as if Diddy takes his time pulling the banana, mostly around the initial few frames. This may be due to the animation being something we haven't gotten used to seeing yet and is just a mere illusion, but it is possible that it was slowed a little. We also don't know anything about the properties of the move, such as B-reversibility and lag, and it is too early to tell if the move was slightly nerfed or not. Until we are able to see more Diddy gameplay footage aside from the clips on Ultimate's website, we can only speculate.
What do y'all think?
(NOTE: The GIF likely plays slower than the video it was taken of, but the visualization is there.)
