i saw another idea of giving echo fighters their own move set in a way that they are more recognizable. i think that would be the best way to do this. the different links are a good example for that
I think reconnecting Zelda and Sheik would be a good idea, and I'd let the freed slot being occupied by Toon Zelda with Captain Tetra as alt. I'd also reconnect Samus and Zero-Suit Samus as they were in Brawl. I think switching characters are cool. As much as characters having other characters as alts. So I'd make Lucina an alt of Marth and Daisy an alt of Peach again. As for Ryu and Ken... It's a bit complicated, since they have evolved in different directions. A possible solution would be to fuse the best of their perks into a single moveset and make Ken an alt of Ryu. Or... Make them even more different than they are in their own series, Ryu stronger and Ken fasters.
Speaking of Snake If they do bring him back Snake Please make it to where he gets new Codec Calls (Plus make it to where Raiden and Meryl are included in the calls) Plus please give Snake some guns to use this time That plus please bring back Cloud and Kazuya That plus give me these characters Crash Bandicoot Spyro The Dragon Rayman Klonoa Abe From Oddworld Gex The Gecko Lara Croft From Tomb Raider Jill Valentine or Leon S Kennedy From Resident Evil The Pyramid Head From Silent Hill 2 To where we can finally have a proper version of PlayStation All Stars
That plus add in more Sonic characters Give me Tails Knuckles Amy Rose Dr. Robotnik/Eggman Metal Sonic Blaze The Cat Silver Ect....................................................
Banjo-Kazooie needs to be rivisited. His side B is broken AF. I'd fix it by making it less powerful but rechargeable. For example: hitting an opponent enough a golden feather will come up.
R.o.b. didn't even meet the old requirements to be in Smash Bros. which were: just be a Nintendo videogame character. He was just a real life toy that didn't do any of the moves he does in smash, I'm assuming lol. It was a big reach by Sakurai to include him in the game in the first place.
