The new trailer for Marvel’s highly anticipated “Avengers: Age of Ultron” dropped Monday night. While fans already have received their first look at the upcoming sequel to Joss Whedon’s 2012 hit, this new action-packed trailer exposes even more details about the plot.

With so much happening in the 1 minute 40 second trailer, including a whole lot of fistfighting, many may lose track of what’s going on. Luckily, we’ve got it all. Below is a breakdown of the most important moments from the second trailer for “Age of Ultron.”

Ultron -- In The Flesh

We’ve known that Ultron reveals his existence to the world by way of a zombie-like Iron Man suit that the artificial being uses to crash a party. However, the first person to say the name in that scene appears to be Bruce Banner (Mark Ruffalo). Now, this either means that Ultron (voiced by James Spader) introduces himself first thing and Banner’s contribution to the moment is to repeat it, or he’s aware of Ultron. Perhaps he had a hand in building him? It’s been previously hinted that Banner is involved in creating Paul Bettany’s character, Vision. It stands to reason that the fellow science bro may have helped Tony Stark (Robert Downey Jr.) build the menacing villain. This would certainly explain his upcoming anger issues. But we’ll get to that.

Uh ... Where Are We?

It’s unclear who or what we’re looking at here, but this mysterious lady by the lake gets prime real estate in the middle of the trailer. It’s been rumored that the Avengers will travel to the fictional African nation of Wakanda, home of the Black Panther, who will be getting his own movie in 2017. Fans are speculating that this scene is our first look at the alleged location.

The Business Of Wakanda

What makes Wakanda so special to the plot of “Age of Ultron”? It’s clear that Ultron will seek to shed his weird half-built Iron Man suit in favor of his final creepy robotic look. It’s been teased previously that he coats himself in vibranium, the same indestructible substance that Captain America’s shield is made of. Andy Serkis appeared in the first trailer looking a lot like Black Panther villain Ulysses Klaw, as noted by Entertainment Weekly. Klaw’s comic-book counterpart has deep ties to vibranium mining in Wakanda. Serkis appeared again in this trailer completely reaffirming speculation that he’s Klaw. After all, it would take a villain to coat a bigger villain in indestructible metal.

Black Widow Origin Story?

The trailer shows a brief shot of what looks like a young Natasha Romanoff (Scarlett Johansson) being forcibly experimented on. I suppose we always knew Black Widow came from a rough background, but with fans clamoring for a stand-alone “Black Widow” movie that’s probably never going to happen, an expanded origin story in “Avengers: Age of Ultron” might be just what the doctor ordered. Pun intended.

Thor Gets Zapped

The trailer shows an image of the god of thunder (Chris Hemsworth) getting zapped by what looks like some of his own lightning powers. While that’s exciting, it’s worth noting that he’s not alone. In the bottom right of the shot viewers can see a barely dressed woman with light skin. Could this be our first look at Asgard in “Age of Ultron”? It’s been revealed that Asgard-based characters Loki and Heimdall (Tom Hiddleston and Idris Elba) will make brief appearances in the film. In addition, a teaser shown at Marvel’s big Phase 3 announcement in October showed a clip in which Stark and Captain America reveal that Thor ran away to parts unknown. Perhaps the hammer-wielding hero went back home to seek help in defending Earth? Perhaps it doesn’t go well? After all, Loki’s sitting on the throne of Asgard and he’s not the biggest fan of Earth or its mightiest heroes.

Hulk Bustin’

We’ve seen the battle between the Hulk and Iron Man’s “Hulbuster” armor teased in the past. The second trailer gave fans a lot more to salivate over. Cars get kicked, roads get destroyed and, we’re just guessing here, some feelings probably get hurt as the two science bros go head to head. In a voice-over during the trailer, Ultron says he’s going to tear the Avengers apart from the inside. It’s unclear what’s making these two allies fight so hard, but it certainly can’t be good for team morale.

What Calms The Hulk Down

It looks like the Hulk eventually learns to control himself again, but how? If Iron Man can’t beat him into submission, it seems like Black Widow might have finally mastered the taming of the Hulk.
