Oh look, the worst video on youtube. Why did you post a link to that, though? It's 14 minutes of this:
Prosecution: Bandana Dee should get in because of (insert good argument about how deserving Bandana Dee is and how easy it would be to make a unique moveset)
Defense: GOOMBA WITH A HAT
Master Hand: The defense has a valid point, I don't like Bandana Dee
end video
EDIT: Oh yeah, and Defense said out that they removed Waddle Dees from Dedede's moveset because Waddle Dees weren't fit for battle. 2 things:
1. They removed that for the same reason they cut Trainer, took Zelda off of Sheik, and, despite completing their models and moveset on the Wii U, cut ICs. The 3DS couldn't handle that many enemies on screen at once, so they replaced side-b with Gordos and gave Dedede a new Final Smash.
2. Even if they aren't, Bandana Dee is much more powerful. I mean, Waddle Dees are pathetic and weak and usually don't even try to attack you, but in his first appearance, Bandana Dee made a massive trench visible from space in Planet Popstar with one punch. I mean, come on. 167 MEGATONS. That is 167 million tons of force, or 374 billion pounds of force. From one punch. This man (puffball?) is the weakest opponent in this game, and he puts One Punch Man to shame. To put that in perspective, it takes 4000 newtons to shatter a bone. The megaton punch deals out 1,663,990,736,128 newtons (1.663 QUADRILLION), which is uhh a lot. I mean, it doesn't touch Kirby's 525 light years per second fastball, but it's still enough to... one punch the solar system? Also, I tried to debunk that argument and ended up with an episode of Game Theory, but whatever.
