Omega Tyrant
Smash Champion
As much as I would love a DQ character to get in, I don't think Slime would satisfy Sakurai's stricter third party requirements, since Dragon Quest lacks worldwide popularity and I don't know if Slime would be interesting enough moveset wise. I additionally think Geno would get in before Slime, as the former has had the long-standing Smash demand and Sakurai has stated he wanted him since Brawl.Regarding ballot popularity, Slime might be a genuine possibility since Square Enix is already involved in this game.
Dragon Quest is the best selling game series of all time for Japan, and the Slime is incredibly popular.
Wolf, Toon Link, and Jigglypuff were always planned to be in Brawl, they were just low priority characters who Sakurai would have cut if developmental demands forced it and kept out of the SSE in case they needed to be cut. It's the confirmed fate of the rest of Brawl's Forbidden Seven, as Sakurai stated there were more low priority characters who were not able to be fit into the game in the end.Almost entirely. I believe in Brawl's case, Wolf, Toon Link and Sonic were added way late in development after the final roster had already been decided for a year. So it's not that it's impossible for things to change, but it's unlikely. Particularly if Nintendo had planned on releasing Smash this winter all along, considering they don't have any other major first-party Switch releases scheduled then besides Mario Party and the Pokemon spin-off.
The only characters who get added mid-development are clones and Sonic in Brawl (the latter which was a big exception because he was originally planned and was the most requested character by a massive margin). The only other alterations made to the original planned roster are scrapping low priority characters who couldn't be finished in time (Brawl's Forbidden Seven and some other characters in Smash 4 that Sakurai confirmed existed but that we can only speculate the identity of), scrapping characters from technical issues (Ice Climbers in Smash 4), and third parties who Sakurai couldn't get the licensing to (initially Sonic in Brawl and probably the fate of Snake in Smash 4).
Echoes aren't just clones, they're clones that are so similar that they're essentially glorified alts. Here is something I wrote earlier explaining the clone spectrum:They fall within the same category as Lucas and Roy regardless. Semi-clones, but not clones, because clones are now Echoes, and since they aren't Echoes, they aren't clones, but since they still have some similar traits in moves that makes them semi-clones. I don't understand going the whole loopdeloop to explain it.
On the topic earlier of Echo vs. semi-clone, it's not an either or situation, cloning exists on a spectrum. Additionally, from what we seen Echoes aren't just clones, they're essentially glorified alts, with practically 1:1 body structure and few actual gameplay differences; Lucina is negligibly shorter with negligibly shorter reach (a matter of a couple pixels, so practically irrelevant) with the exact same movement specs/physics while all her moves function the same with the same frame data as Marth's (just with consistent strength throughout and no tipper), and then Dark Pit is the exact same in everything except for his f-tilt having weaker knockback, his jab finisher having a smaller hitbox (this one probably an oversight after a patch made Pit's bigger without doing the same for Dark Pit), altered arrows (stronger with less control), an altered side-b (stronger with horizontal knockback), and a different final smash. Even the Melee clones were substantially more different than this (as they had different shapes/sizes, different movement specs/physics, different frame data and damage/knockback values on pretty much all attacks, many moves having altered functioning, and even a unique move here and there). Dr. Mario avoids the Echo designation for this reason, while calling him a semi-clone is still not accurate from what we seen. The general cloning categories goes like this:
*Echo Fighters (as covered prior)
*Clones (most if not all moves cloned from another character, but most if not all aspects have been altered substantially so that they are legitimately distinct in how they play; the six Melee clones and 64 Luigi are examples).
*Semi-clones (has a significant portion of their design/moveset cloned from another character, but has just as much or more that is unique to them or drastically altered that labelling them just a clone is misleading; 64 Jigglypuff, post-64 Luigi, post-Melee Falco and Ganondorf, Toon Link, and Lucas are examples).
*No real accepted term for this; characters with a few cloned aspects but mostly unique (Wolf, post-64 Jigglypuff, 64 Captain Falcon and Ness are examples).
Then additionally the individually categories themselves are on a spectrum; for example among the Melee clones Ganondorf is significantly more different from his source character than Dr. Mario is, and among semi-clones Lucas for example is close to the semi-clone label being questionable while Brawl Toon Link is on the opposite end of the semi-clone spectrum.
