The word of comics and the world of professional wrestling have one big thing in common: nothing is better than seeing two of your favorite characters duke it out in a highly anticipated battle royale. The MCU is no different: it’s exciting to think about our favorites finally getting the chance to team up, but what if they fight each other instead? Batman v. Superman was a little anticlimactic in that regard, but Captain America: Civil War really made it difficult to choose sides when half of the Avengers turned against the other half. Vin Diesel seems to think another battle between two very large team members might happen onscreen: Groot vs. Hulk.

While talking with Screen Junkies at Brazil’s Comic Con to turn up the hype for xXx: Return of Xander Cage, Diesel said that the Groot-Hulk fight is going to happen, it’s just a question of when.

Screen Junkies: Are we ever going to see Groot and Spider-Man in one movie?

Vin Diesel: That’s an interesting question. I think, if it’s up to James Gunn, you’re going to see a Groot/Rocket movie after [Avengers:] Infinity War. I think that’s highly possible. We shall see. I know that, somewhere in the universe, you’re going to see Groot and Hulk battle. I know it. You can write it somewhere, you’re going to see that poster: Groot vs Hulk.

This is the Mayweather vs. Pacquiao of the Marvel universe, and it’s not without precedent. It’s been drawn on an Incredible Hulk cover before, and was done in animated form in the “Michael Korvac” episode of The Avengers: Earth’s Mightiest Heroes. Hulk is known to be pretty volatile as his transformation is difficult to control, and Groot is nothing if not a berserker in battle, so seeing these two going at it, possibly when the Avengers meet the Guardians during either of the Infinity War installments, would be one epic fight.

But before that can happen, Groot will need to gain a few feet back. JUST LOOK at Louis D’Esposito’s little maquette!
