Second Avengers: Doomsday Teaser Ignites Marvel Fan Frenzy Over [Spoiler]

Marvel just slipped a second Avengers: Doomsday teaser into theaters, and this one is all about Thor. It is attached to Avatar: Fire and Ash, so if you are headed to that, you will see it on the big screen first. The vibe? Somber, focused, and very much setting up what Thor is up against this time.

What the new Thor teaser actually shows

• Thor is front and center, sporting the short hair again, which immediately calls back to Ragnarok and Infinity War. The armor has fresh gold accents that pop under the lighting.
• The tone is low-key and serious. Marvel is clearly trying to sell the scale of the threat, which is Robert Downey Jr. as Doctor Doom. Yes, that pairing is real, and the teaser leans into it.
• We see Thor praying to Odin and the other All-Fathers. He is not just asking for the power to take on Doom; he is asking to make it out alive and get back home.
• That 'home' is Love — the kid Thor took in at the end of Love and Thunder after defeating her father, Gorr the God Butcher. The teaser makes that personal stake explicit.

The reaction so far

Fans are into it. A lot of the chatter is that this Thor-focused piece lands better than the earlier Steve Rogers teaser. Some even said this should have been the first one out of the gate. One reasonable counterpoint: that initial spot existed to confirm Steve Rogers is in Doomsday at all, which was a big swing meant to jolt the general audience.

"Not gonna lie, that Thor teaser for Avengers Doomsday is extremely effective at building up the threat that is Doctor Doom. Seeing Thor praying to the All-Father that he can make it out alive in the upcoming battle is some powerful storytelling."

Style-wise, people are happy the Infinity War haircut is back, and the gold detailing on the suit is getting love. There is also a thread of 'Thor is back and Love is part of this? Sold' energy floating around — which tracks, because the footage clearly wants you to feel the weight of what he could lose.
