Move changes have been solemnly spoken of. Let's talk about those.
There needs to be some serious moveset changes this time around. Donkey Kong's moveset now is terrible.
Copy/Paste Moveset
Donkey Kong
I remade DK's moveset so that it's actually from his games.
Walljump: Yes (he can wall jump in Jungle Beat, even though it bothered me that DK was the only DK character in it, he can still do it, plus DK is a platformer character and even in Smash he's designed on being an agile heavy weight.)
Wall cling: No (He doesn't cling to walls, obviously.)
Crawl: Yes (DK can crawl, he does it to get under things in DKC.)
Specials
Up B: Barrel Cannon, he gets into a barrel cannon and it's the type that rotates around and you press A to make it shoot at the desired point. Sonic makes a spring come out of nowhere, DK can do it too. This was a major part of DKC. (Origin: DKC)
Neutral B: HIS COCONUT GUN IT FIRES IN SPURTS IF HE SHOOTS YA ITS GONNA HURT. It helps DK with ranged characters, he does it in his games, and it's an original projectile because it fires in spurts. (Origin: DK64)
Side B: Roll, it's his signature move from DKC why wasn't it in Smash? Anyway, it functions as an attack that does mild damage, and has some lag at the end, yet if the move connects it erases the lag (the exact same as in Donkey Kong Country.) Now I'm going to quote Cranky Kong on this one "Roll off a platform and jump to do a Super Jump!" Think of the combo potential. I love just thinking about it. This is a perfect move for Smash. Albeit a bit complex. >_> (Origin: DKC)
Down B: Same, I actually like this move, go figure. (Origin: DKC)
Dash Attack
Dash Attack: Supports self with hands and swings forward with both feet. (Origin: DK64)
Standard A Combo
Standard A Combo: Slap, slap, both hands down slap. (Origin: DK64)
Tilts
Forward Tilt: Same, but this move would be weaker, but have a bit nicer reach. (Origin: DK64)
Down Tilt: Punch at the ground two times. (two hit attack) (Origin: DK: Jungle Beat)
Up Tilt: Clap, creates a ball of sound that hits all around him. (This isn't as over powered as it sounds guys, it does low damage just like most tilts, and his up tilt hits all around him in Brawl.) (Origin DK: Jungle Beat)
Smashes
Forward Smash: That awesome looking uppercut from the link I put up here. Would KO off the top of the stage and imagine getting a hit the screen KO from that. @_@ (Origin: DKC2)
Up Smash: He would have one of those freak moves like Ganny's up tilt and half of Snake's moves. DK would duck and throw an orange above him and the orange would asplode. (Origin: DK64)
Down Smash: DK makes a wide stance and slams his arms out to the left in right like when he breaks out of the ropes in DKC2 (yeah this is sort of lame, I'm sorry. ) (Origin: DKC2)
Aerials
Forward Air: Same, one of the 3 moves I liked. (Origin: DK64)
Down Air: Does a ground pound, it has a hit box that surrounds DK when he lands, but he's still a bit vulnerable. (Origin: DK64)
Uair: DK spins counter clock-wise with his foot out, if people get hit they get carried around with it and spiked at the end. Yes, a uair that spikes, how awesome. This would have tricky timing similiar to Ness' dair though. (Origin: DK: Jungle Beat)
Neutral Air: Pulls himself into a ball, like rolling off a platform in DKC, you could attack people in the air in front of you. (Origin: DKC)
Back Air: DK hits people with his back while doing a backflip. One of the more lame moves, I know. (Origin: DK64)
Throws
Forward throw: Cargo'ing I actually did like this move, I forgot about it. (Origin: DKC, or if you want to include the "Donkey Kong" Donkey Kong, Donkey Kong.)
Up throw: Has a forwardish knock back, the way DK threw barrels in DKC. (Origin: DKC)
Down throw: Jumps ontop of the opponent and punches rapidly. (Origin: DK: Jungle Beat)
Back throw: Gorilla Grab, grabs to foe and pulls them backwards forcefully. (Origin: DK64)
Other things that need to be changed...
Mario's f-smash changed to a hammer. Mario's side b swapped for fire balls, neutral b swapped for Luma Spin. Mario's FLUDD doesn't need to be primed. Mario's up b changed to hover nozzel. New dair is ground pound.
Luigi's down b changed to Poltergust, some of his other moves need to be changed, but I don't have any ideas at the moment.
Bowser's up b needs to be the shockwave jump from Mario 64 and Galaxy. Down b needs to shoot flames in the air as an anti-air move. Old down b as new dair.
There's some obvious changes that need to be made like Ganon and Falco, but I don't really feel like doing it now.
