The long-awaited teaser trailer for "Guardians of the Galaxy Vol. 2" at last arrived this evening, bringing with it as much action, humor and '70s rock as Marvel Studios could cram into two minutes.

Beyond Rocket Raccoon's warning that "the fate of the universe lies on your shoulders," the new entertaining new footage doesn't reveal much, if anything, about the sequel's plot, which we know involves Peter Quill's search for his true father. That said, there's still plenty in the teaser to appreciate -- and unpack!

To that end, here are our eight favorite moments (and elements):

"Showtime, A-Holes!"

Chris Pratt's Star-Lord may have coined the new "Avengers Assemble!" or "To Me, My X-Men!" with "Showtime, A-Holes!," a phrase that's almost certain to launch dozens of memes, and land more than a few kids in detention. It's of course also a nod to the scene in the 2014 original, where the Guardians are labeled as "a bunch of a-holes."

It's the Year of The Sweet

guardians2-2

Between the use of "Ballroom Blitz" in the "Suicide Squad" and "Fox on the Run" in this trailer, the 1970s British glam rock band The Sweet is having a stellar year, and will hopefully reap royalties from the inevitable iTunes sales. Two versions of the band remain active with original members, so perhaps we can look forward to a Sweet Superhero Tour. Now if only "Little Willy" can find a place in "Thor: Ragnarok" ...

Baby Groot is Somehow Adorable and Ferocious

guardians2-3

We already knew from the end of "Guardians of the Galaxy," and the subsequent merchandising avalanche, that the li'l sapling is cute as a button. But who expected Vin Diesel's voice to sound like that? Or for Baby Groot to wear a costume (that looks more than a little like Star-Lord's)? Or for him to be able to strike fear in a full-sized human?

The Hilarious Visual Callback to the First Film

guardians2-4

All right, you knew coming into this that Baby Groot and Rocket Raccoon would get a lot of screen time, and perhaps the lion's share of the attention. But, hey, it's all earned, particularly with James Gunn flipping the script on the prison-escape scene from the first film by having Groot ride on Rocket's shoulder as the camera spins around them.

Gamora and Drax vs. That Giant Alien Monster

guardians2-5

It's tempting to refer to Drax the Destroyer and Gamora as the Guardians' greatest fighters, but Rocket would undoubtedly have something to say about that. However you think of them, they're in fine form as they go up against the enormous, tentacled alien -- it's like something out of "Watchmen" -- armed with nothing more than their blades. Who needs guns when you can kick that much ass?

Baby Groot is Trusted With an Atomic Bomb

guardians2-6

We can only imagine the circumstances under which it falls to Baby Groot to safeguard a weapon of mass destruction. However, it's a delight that so much of the teaser is devoted to a frustrated Rocket trying to instruct him on how not to kill everyone, before giving up and searching for tape to cover "the death button." Ultimately, of course, Rocket's efforts don't appear to matter.

Mantis Doesn't Understand Boundaries (or Secrets)

guardians2-8

Pom Klementieff is instantly memorable in her debut as the empathic Mantis, who can sense the emotions of someone simply by touching them. Unfortunately for Peter Quill, she was raised by Ego and doesn't really comprehend social interaction, leading her to publicly reveal his "sexual love" for Gamora.

Drax Actually Has a Sense of Humor

guardians2-7

Although Star-Lord may not appreciate Mantis' uncomfortable revelation, Drax certainly does, which leads to something we couldn't have imagined in the previous film: an uproarious laugh. The stoic warrior who couldn't even grasp a metaphor in the first "Guardians" -- "Nothing goes over my head" -- can now relish Peter's discomfort, and then excitedly ask for Mantis to sense his feelings.
