Robert Downey Jr.'s Father's Day Post May Confirm Major Avengers: Doomsday Rumor - Possible Spoilers

Avengers: Doomsday star Robert Downey Jr. has shared a new social media post that, despite serving as a celebration of Father's Day, may also drops a big Avengers: Doomsday tease.

Avengers: Doomsday star Robert Downey Jr. has celebrated Father's Day with a new piece of Doctor Doom artwork. Presented in the style of a child's drawing, it shows the villain alongside his son as they both fly kites.

However, upon closer inspection, we see that they're emblazoned with the Avengers and Fantastic Four logos with a "no" or "prohibited" symbol emblazoned over them. Someone clearly isn't a fan of their dear old dad's greatest foes!

Is this just a fun post from the Oscar-winner, or might it have a deeper meaning? Getting into spoiler territory, it's previously been reported that Doom's wife and child die while he's investigating the Incursions that are laying waste to the Multiverse. That's a major departure from his comic book origin. 

When the ruler of Latveria later discovers that Steve Rogers was responsible (after travelling back in time in Avengers: Endgame for his happy ending with Peggy Carter), Doom enacts his revenge by murdering the former Captain America's son. So, yeah, Avengers: Doomsday could be about to get really dark.

"A lot of it has been...there's some experimentation," Downey recently said of his approach to playing Victor Von Doom. "We've had our moments of, 'Let's shift here.' But we landed in a place that I think will more than suffice. And it's not even about how I executed it. It's about the way it's been structured, and the other characters."

"There's something going on in Doomsday, and forward that is literally the only antidote to, 'How do you not have these films be let down after an Infinity War and an Endgame?' And boy, have we laboured long and hard to bring that down."

"I'm quite odd in that I try to stay as removed from a subjective experience of things as I can," he continued. "So I try to think like the brothers. I try to feel like I'm in the writing room. I try to feel all that stuff. But eventually, there are so many big shoes to step into that I just have to go, 'What hasn't been done as well as it can be done yet?' We're always looking for that opportunity."

Check out Downey's post below, and let us know your thoughts in the comments section.

Man I hope for the best with this movie but don't know after all the spoilers I've heard

@0bstreperous - I fear they have run out of ideas and will pull out just another MoM or DP&W. All (nostalgic) smoke and mirrors with little to no substance.

@Fogs - yeah, I've been listening to spoilers since NWH something I would would have never done before then but I listen to Den of Nerds at work and it's either mind numbing monatany of work or spoilers

This movie sounds like it's not a simple pitch you know? Too much going on

@Fogs - I hope you are wrong but suspect you are correct. After Endgame, and to be honest really even after infinity War they had already run out of ideas. I think they would be better off scanning through the older comics and reusing the good storylines. Hopefully if they do this with Secret Wars it’ll all come good.

@0bstreperous - Oh. You mean "rumors"...

@IAmAHoot - no it's not rumors since I've been listening to them they've been correct for the most part and it's leaks over the course of about a year with the "rumors" being refined

It's a fine line between ruining the movie for myself

@Spike101 - I mean, what are the stakes? Incursions? Like in MoM? The end of all realities? Like in Loki or DP&W?

I mean, there's no plan being laid out, which only got worse with the whole J.Majors situation.

Because there was a time where, failed as it was, thor knew about the infinity stones and went to investigate what it was about, and each stone appeared in a different film. Little by little we learned about it, until in GoTG the whole plan was exposed with Thanos.

Why should we care about Doom? What could be worse than what we saw in previous films? I don't know... I really feel they seriously lost track of the storyline. And add to it a bunch of weeeak, weak characters after the strong MCU roster being dismantled.

I'm sorry to say I have little faith in the MCU's future right now.

Honestly , I could see this being a tease story wise into Doomsday or his version of the character atleast but RDJ has posted this type of art before that have just been cute & winking towards his current big role so I wouldn’t be surprised if this amounts to nothing aswell.

If his rumored motivation is true , then it reminds me of Iron Man:Armored Adventures where that iteration of Doom had no ties to the FF and was a member of the Latverian royal family that lost them all because of a failed experiment that also scarred him so if they are going that route then I think it could work but we’ll see.
