Hey everyone, I'm from the Isaac thread. I'm not sure how you all currently feel about the possible leak. I'm personally 50/50 on it, but as a fellow Pokemon fan I wanted to give you all hope in the off chance that the mural leak turns out to be real. It is possible for Incineroar to be DLC! Let me explain:
As a long time Pokemon and Smash fan since the first games in both franchises, Pokemon has a strange pattern when it comes to which ones are chosen to be playable...the ANIME!
Right now there is only one Pokemon character that ties more towards the game than the anime and that is Pokemon Trainer. However two of the main Pokemon with him were staples of the anime's main protagonist Ash being Squirtle and Charizard, Ivysaur was only picked over Bulbasaur because Sakurai wanted to feature the stages of evolution. Anyways all the others had prominent roles in the anime:
Pikachu - self explanatory
Jigglypuff - used for many comedic moments throughout the anime and is still used today.
Mewtwo - star Pokemon of the first movie
Pichu - star Pokemon of the Pikachu animated short that aired before the second movie. (released a full year before Melee released)
Lucario - star Pokemon of it's own movie, used heavily to promote gen 4
Greninja - personally given to Sakurai before it's game released, happened to be Ash's star Pokemon is Kalos and received its own new form.
Right now in the anime Ash currently has a Torracat which I'm sure you all know is the pre-evolution of Incineroar and it is widely speculated that it will be the star Pokemon on Ash's team. Now some people may be wondering why Incineroar would be DLC for Ultimate if Gen 8 will be dropping next year? Well although the hype will be around Gen 8, the anime will still be in generation 7 that entire year and there is always the possibility of Incineroar getting a new form similar to how Greninja got during the Kalos season. The most interesting thing about that possibility is that Greninja's new form was NOT available in the games until Generation 7's Sun and Moon! It is extremely possible that if Incineroar gets a new form then it would be used to hype up the Gen 8 games and with the new info on the Smash site we know for a fact that Greninja's final smash involves it using the Ash-Greninja form as it states on the Smash Blog post for Greninja.
With all that being said, if Incineroar is going to receive a new form similar to Greninja then I doubt GameFreak would want that to be spoiled before they announce it. So the possibility of Incineroar being DLC is extremely likely as a possible form can be used to hype up Gen 8 just like Ash-Greninja was used as hype for Gen 7.
Again I'm 50/50 on this mural leak but even if it turns out to be real I still believe Incineroar would have a strong legitimate chance at getting in for DLC.
