ok i dont plan to start drama but basically skip n jana had their unique mechanics like scrap/saber & dash, but kou pretty much reuses another char steph made's punching and can climb like knux (hes the knux counterpart basically)
although its been 5 months since his reveal so im probably underestimating the update
and yes i do appreciate the work for the sprites and special effects since they always look great
lets not make this a big argument (i wouldnt want that its a pain to look at dramatic stuff going on)
quick edit: hold up ima watch the trailer again
quick edit 2: he can also do some sorta dive attack and a stomp if he falls from high enough, probably am underestimating (and breakdance)
