On Reddit, u/litbacod4 posted an image of Dave Bautista and said that the actor would make a perfect Sparky-Sparky Boom Man, an in-universe joke directed at Combustion Man. Others also felt the same, with u/Angorian44 saying, "[It's] so uncanny, it almost makes it seem like they designed CM with [Bautista] in mind." U/ikhalid1418 suggested that the wrestler Kane from the WWE would make an excellent Combustion Man, while u/flyingboarofbeifong replied, "Combustion Man is straight-up jacked, though. Kane is a complete slab of a man, but he's the type of big that is pretty consistently large all around and doesn't look really well built in spite of the fact the dude could chokeslam a small car. Bautista has the same ox neck effect going on as Sparky Sparky Boom Man."
However, fans on Reddit aren't the only ones who think Bautista would make a perfect Combustion Man in Netflix's live-action show. "Avatar: The Last Podcasters" has also announced its support for the casting on Twitter. Considering that Collider confirmed that Netflix's "Avatar: The Last Airbender" finished filming around June 22, 2022, as well as the cast roster on IMDb, it appears as if an actor has not yet been tapped for the role of Combustion Man. This means that perhaps if enough fans clamor for Bautista to become the terrifying assassin, it may happen. He certainly looks the part, and as Bautista has proven in "Guardians of the Galaxy," he is more than capable of playing a stoic and singularly focused individual.
