Today is a very big day for superhero fans at San Diego Comic-Con, with two huge panels happening in Hall H. First up is Warner Bros.' panel where new footage from Wonder Woman and Suicide Squad will be revealed, and Marvel Studios will showcase their upcoming slate. While Marvel hasn't confirmed which movies will be showcased, we know that Doctor Strange and Guardians of the Galaxy 2 will be featured, thanks to confirmations from the filmmakers, but today we have a sneak peek at some important props from another Marvel movie, Thor: Ragnarok. The studio has unveiled the gladiator armor that Hulk will use in this highly-anticipated sequel.

The reveal was made on Twitter by Marvel's Ryan Penagos, a.k.a. Agent M, with a new video and detailed photos of this armor. One of Agent M's associates reveals at the end of this video that they just got these props in from the set in Australia, where Thor 3 is currently filming. The video and photos reveal a massive helmet, armor and two huge weapons that Hulk will be using, which seemingly confirms a few long-held rumors about this superhero sequel.

Marvel still hasn't revealed any specific plot details for Thor: Ragnarok, but there have been plenty of rumors swirling about the story, long before production got under way. One report called this movie a "mashup" of the Planet Hulk comic book story line, which fans have long wanted to see on the big screen. After taking off for parts unknown in Avengers: Age of Ultron, it is reportedly revealed in Thor: Ragnarok that Hulk has landed on some sort of gladiator planet. After the villainous Hela (Cate Blanchett) banishes Thor (Chris Hemsworth) from Asgard and destroys his hammer Mjolnir, Thor winds up on this gladiator planet where he's reportedly forced to fight the current champion, Hulk.

We have also heard several times that both Thor and Hulk go on a "cosmic road trip" together, but there isn't much else we know about the story. It's possible that Chris Hemsworth, Mark Ruffalo and other cast members could have a video message for the fans in Hall H during today's panel, since they most likely won't be able to make the trek from Australia with production under way. Since this armor was unveiled at the Marvel stage at SDCC, it certainly could be just the first of many updates for Thor: Ragnarok that Marvel plans to unveil today.

The cast of Thor: Ragnarok also includes Jeff Goldblum as the eccentric Grandmaster, Tessa Thompson who will bring the classic hero Valkyrie to life on the big screen, and Karl Urban who will add his might to the fray as Skurge. Tom Hiddleston (Loki), Anthony Hopkins (Odin) and Idris Elba (Heimdall) will also reprise their roles from the first two Thor movies for Thor: Ragnarok, which is set to hit theaters on November 3, 2017. Take a look at these photos and video from the Marvel Comic-Con stage, featuring the new Gladiator Hulk armor from Thor: Ragnarok.
