No. Usually Smash goes for the most iconic and recognizable Pokémon to be playable. Dracovish is neither of those things.
Not a chance. Ultimate is already done and we are who even knows how long till a new Smash. Most likely it would be the most recent Gen once that game appears, and even if they somehow picked a Galar Pokémon, there are far more popular choices out there.
Absolutely not. If I was to give Dracovish any kind of credit, if they ever brought back Spirits, Dracovish would make a very interesting one. Aside from that, basically what the others said above.
They should make Dracovish the only playable character in the next Super Smash Bros. Then the game might actually be good.
That's honestly the only way I see it getting in. Considering even Swirlix made it in, Dracovish might have a shot. The main problem is, what can Dracovish do that would make it a unique Poké Ball summon? Fishious Rend's move uniqueness is like 90% based on Speed and things like that, which doesn't really carry over to Smash. One possible idea is that it would use Fishious Rend after taking damage over a window of time, then deal it to the players that attacked/opponents, or just fire a blast with a hitbox/damage proportional to damage taken, kind of like a one-shot Lucario summon.
They should make Dracovish the only playable character, the Pokéball summon, the assist trophy summon, the stage boss, the story boss, and every trophy. We will call it Super Dracovish Bros. In the beginning there was only Dracovish. In the end, there will only be Dracovish.
You'll have to be more specific than that. As CEO of Dracovish Enjoyers Inc., I feel like a qualified expert in all things Dracovish. Although, you seem to know a lot too.
I think you might be the only dedicated enough Dracovish fan to do that. BE THE CHANGE YOU WANT TO BE IN THE WORLD. SHOW UP AT MASAHIRO SAKURAI'S HOUSE AND BEAT HIM AT HIS OWN GAME, THEN YOU CAN ADD WHATEVER YOU WANT as a Mii costume
