Loki! Loki! Loki! And Tom puts his finger to his lips and the whole crowd goes silent. 💚

Disney brought Robert Downey Jr back and they're gonna make him do it til he's 90.

Doctor Doom: *face revealed to be Tony Stark*

Tom Holland Spider-Man: *confused screaming*

[sogwatchman]

RDJ as Tony Stark was great, Ryan Reynolds as Deadpool is amazing but Heath Ledger as Joker was just insane. Best portrayal of a comic book character IMO.

RDJ might be returning to the MCU as Dr Doom but he’ll always be Iron Man

[aeineeabas]

Loki's entrance will always be epic 😂 and don't forget the "MY WIFE LOVES YOU!!!" man in the hall H 😂😂😂

RDJ Returns as Dr. Doom was surprising 😱

[DinGrogu]

Michael Keaton is my favourite Batman. Superb casting 😊

[AlexAlexis-rdpb]

It would be insane, if they do a clash between Doctor Doom and Loki Prime!!!! This can really happen....

[CandiceVidito]

Luke Skywalker joins Spongebob. Wow did not see that coming.

[ARIXANDRE]

Man, Robert Downey Jr is just swimming in money. He deserves it.

[Slayde.Wilson]

For those who are against Robert Downey Jr as Doctor Doom. Please keep in mind that he already has met for the role back in 2005 before Iron Man. So, I dont see what the problem is with this.

Seeing RDJ as Dr. Doom was very cool. 🎉

One time, one of my cousins and her ex-husband went to this Comic-Con, and while they were there, they met Stan Lee, got their picture taken with him, and he signed the picture! I'm still very jealous they got to do that. Also, there's this guy who I've seen as a customer at work a couple of times, who, like me, is also a big fan of Star Wars. He and his parents told me that he got to meet Mark Hamill, Billy Dee Williams, and the person who played Darth Maul. I think they said their son met them at Disney about a couple or 10 years ago. That also made me super jealous.

I’m a bit skeptical about RDJ being Doctor Doom. One one hand, I would’ve preferred another actor to take on the character. But on the other, we’ve seen how good RDJ can act outside the cool guy Tony Stark archetype, so for him to play another Marvel character so wildly different from Iron Man can potentially be interesting. And depending on the direction they take with Victor Von Doom, RDJ could pull it off.

Remember that this is a character that we only ever see wearing his mask because of the accident he had with the Fantastic Four which left his face permanently disfigured, so they don’t need to rely so heavily on RDJ’s face.

[SpammytheHedgehog]

Funny thing is that Iron Man & Dr. Doom had fought each other numerous times.

[GamerFunOriginallyAarush]

Robert Downey Jr. as Doctor Doom is a crazy return!

[vanada]

Despite anything, having RDJ and Chris Evans (even Chris Hemsworth too just not MCU panel if i'm not mistaken) back to comic con in 2024 is a sweet surprise and a big win for the fans who've missed them and thought we'd never see them there again.. the OG will forever be missed and loved♡
Also the most iconic comic con appearances for me are Loki and Jack Sparrow..nothing else can compare

3:21 Optimus just giving a speech like we’re going into battle and the Thousand Sunny is just chilling behind him 😂
