Incineroar is an unlockable character in Ultimate. It poses after landing attacks to show off, but the poses can easily be cancelled into guards and other attacks. Incineroar is among the slowest-moving characters, with its grounded mobility in particular being the absolute slowest in the game. This is compensated with an excellent set of throw attacks, as well as many of its other attacks being surprisingly fast despite their high power, with several attacks such as Darkest Lariat having transcendent priority. Being a Fire-type, it takes continuous damage while swimming, a trait it shares with Charizard, Inklings, and Sonic.
When Incineroar pulls off certain attacks, it'll pose for the crowd if it hits, or react in anger if it misses. These poses can be cancelled out to avoid being left open.
Incineroar's Classic Mode route is called Burning Pro Wrestling Spirit! In this scenario, Incineroar fights other heavyweight characters in a tournament-style scenario. All rounds except the final and bonus round take place in the Boxing Ring.
Its last boss is Master Hand, who is joined by Crazy Hand if the player reaches the fight at intensity 7.0 or higher.
- Pit: Ha! That tiger's on fire.
- Palutena: How astute of you, Pit. That's Incineroar. Before it evolved into this form, it was a cute little Litten. Incineroar is unpredictable, self-centered, and rambunctious. Although it's supposedly great with children.
- Viridi: It specializes in wrestling moves. Brute force is its M.O., but it's no slouch in the technical department either.
- Palutena: Incineroar is also a performer at heart, so when it lands a big attack, it likes to show off for the crowd.
- Pit: Now that you mention it, I do hear crowd cheers sometimes. It's almost like an audience is watching us fight.
- Palutena: Incineroar has an attack called Revenge that feels like it was inspired by pro wrestling. If Incineroar takes damage while Revenge is active, its body ignites, and its attacks become more powerful!
- Pit: If that happens, I'll just let everyone else fight Incineroar until it wears off. Then I'll swoop in and steal the KO!
- Viridi: Sure, if you wanna be THAT guy. Might as well edge guard while you're at it.
- Incineroar's original move, Alolan Whip, is based on the Irish whip, a move in professional wrestling.
- Unshō Ishizuka, the Japanese voice actor for Professor Oak, provided the Japanese voice for Incineroar in Ultimate before his unexpected death on August 13, 2018. Ishizuka recorded all of his voice clips for the game before his death.
- Incineroar was largely added in because Masahiro Sakurai had never done a wrestling fighter before, and also because, as Pokémon Sun & Moon were nearing release at the time Ultimate was nearing the end of development, a character from that game was reserved for the remaining spot so Sakurai could have at least one character from a more recent game included. In large because of this, Incineroar is the only non-DLC character in Ultimate to not be part of the original draft for the game written on December 2015.
- Both Incineroar and Decidueye were considered for inclusion in Ultimate, but the latter was passed over.
- All of Incineroar's moves are Physical attacks. This makes it the only Pokémon whose moves are all under one Damage category. While Ivysaur's Specials are also Physical, it uses Solar Beam for its Final Smash.
