We can talk all day about Marvel's mightiest heroes, the lives they've saved, the money they've earned... but isn't it so much more fun to talk about Marvel's villains?

From Iron Monger landing in the first "Iron Man," to Ultron threatening to wipe out mankind in the new "Avengers," and all the Loki in between, Marvel's villains put their money where their mouth is more often than not — although there is the occasional "not."

Here's a look at all of the biggest bad guys in the Marvel Cinematic Universe, from bottom of the barrel to the top of the Sokovian mountain:

Baron Strucker ("Avengers: Age of Ultron")

Thanks for the Twins, though?

The Other ("Avengers," "Guardians of the Galaxy")

Talks a big and bad game to Loki, gets incinerated by Ronan the Accuser five seconds later. Not impressed.

Algrim ("Thor: The Dark World")

Pains me to rank the man formerly and alternately known as Mr. Eko and Simon Adebisi this low, but Adewale Akinnuoye-Agbaje was wildly underutilized in the Marvel Cinematic Universe. Better luck with Killer Croc!

Whiplash ("Iron Man 2")

He loves birds. How bad can he be? Pretty bad once you put a whip in his hands. But not as bad and not as weird as some of the other people coming up on the list.

Abomination ("The Incredible Hulk")

Underrated villain in an underrated movie. Tim Roth as Emil Blonsky is the real winner here, with Abomination coming in distant second after his human counterpart, running around with super soldier serum coursing through his veins. He's like Jack Bauer meets Gollum.

The Destroyer ("Thor")

The Hodor of the Marvel Cinematic Universe's rogues gallery, this suit of armor lacks in personality, but shines in badass action scenes.

Malekith ("Thor: The Dark World")

Christopher Eccleston looks fantastic and feral as the warmongering Dark Elf, but he lacks the charm and menace of some of the other Marvel baddies.

Laufey ("Thor")

How can you go wrong when you have Colm Feore playing a Frost Giant? You can't. It was a trick question.

Crossbones ("Captain America: The Winter Soldier")

I look forward to knocking Frank Grillo's Brock Rumlow higher up the list as soon as he reemerges with his signature mask and attitude in "Civil War." Until then, here he stays.

Batroc the Leaper ("Captain America: The Winter Soldier")

Minimally used, but who needs more than what we got? He provides the reason for the opening action sequence in what's pretty easily the best straight-up action movie of the MCU.

General Thunderbolt Ross ("The Incredible Hulk")

Betty Ross' daddy and Hulk's big baddie deserves a return appearance in the MCU. Here's hoping we see William Hurt's mustached military man again down the line… maybe wearing a certain shade of red?

Justin Hammer ("Iron Man 2")

I am not the world's biggest fan of "Iron Man 2," but I love me some Sam Rockwell. Like Thunderbolt Ross, Hammer's another guy I would love to see in the movies again.

Obadiah Stane, the Iron Monger ("Iron Man")

You gotta respect the original MCU bad guy, even if he's considerably less threatening than the others we've seen over the years. A little Jeff Bridges goes a long way.

Klaw ("Avengers: Age of Ultron")

We've barely scratched the surface of Ulysses Klaue, the number one nemesis of Black Panther. But a scratch was all we needed to (A) remove his arm and (B) get fully pumped up for future Klaw appearances. Andy Serkis and Marvel, together, strong.

The Chitauri

The most punchable faces in the Marvel Cinematic Universe. Especially that dumb Leviathan.

HYDRA

Cut off one head and another one will take its place and destroy your entire S.H.I.E.L.D. infrastructure. Pretty impressive stuff, honestly.

Alexander Pierce ("Captain America: The Winter Soldier")

Robert Redford in a Marvel movie. Respect.

Ronan the Accuser ("Guardians of the Galaxy")

Hard to imagine that the man beneath the Ronan makeup was once a frontrunner to play Star-Lord himself. Then again, maybe you forgot that it's super-hot Lee Pace under there. It's a testament to Pace's awesomeness as an actor, that he could become so thoroughly transformed as the one of the galaxy's greatest threats.

Arnim Zola ("Captain America: The First Avenger" and "Captain America: The Winter Soldier")

World War II version or modern-day computer version? Take your pick. In either case, Toby Jones is positively freaky as the HYDRA doctor. He's a long way from Dobby.

The Mandarin? ("Iron Man 3")

For many Marvel fans, there's only one truly egregious misstep as far as the villains go. The Mandarin did not land for everyone. But he landed for me, in a very big way. Huge props to Marvel for having the nerve to pump out such a bizarre and hilarious twist, with Ben Kingsley totally game for the gig. Guy Pearce's Extremis-infused industrialist deserves some credit too, if only because Guy Pearce is awesome.

Red Skull ("Captain America: The First Avenger")

Years ago, I visited the first Cap movie's London set and participated in a three-minute group interview with Hugo Weaving in full-on Red Skull makeup. It remains one of the most terrifying moments of my life, let alone my career. So I'm biased, but still, Red Skull's an iconic villain, and the Wachowski regular did a stellar job bringing him to life. It's a shame that both he and Marvel no longer seem interested in this horrifying character.

Nebula ("Guardians of the Galaxy")

Karen Gillan went full Sigourney Weaver circa "Alien 3" in order to become the bald, blue, badass daughter of Thanos and sister of Gamora. She's not the central villain of "Guardians of the Galaxy," but she's by far the most interesting, the one with the coolest design, the one with the most could-not-give-an-eff attitude, and the one with the most potential. Cannot wait to see what Gunn does with her in "Guardians 2."

Thanos ("Avengers," "Guardians of the Galaxy")

Okay, so maybe Thanos is a wee bit more interesting than Nebula, but that's because of how long we've been waiting for the purple-skinned, Death-courting, gauntlet-wearing villain to make his move. By the end of "Age of Ultron," he looks like he's finally ready to pop. Well, so are we. Grab some shawarma and strap in, because "Infinity War" is going to be one hell of a ride.

Ultron ("Avengers: Age of Ultron")

James Spader's turn as the maniacal machine stands out as one of the greatest Marvel Cinematic Universe performances of them all, and that says a lot, given that we don't even see Spader's face in the whole movie. His hatred and his pain are raw and real, reflections not just of Tony Stark (and Joss Whedon), but of the wounds that all of us nurse. Like it or not, there's a lot of Ultron in all of our hearts. Cut those strings accordingly.

Wilson Fisk ("Daredevil")

Okay, so he's not in the Marvel movies, but he's in the Marvel movies' same universe, and "Daredevil" might as well be a movie, so roll with it. That's how much I adore the man who will one day be known as the Kingpin of Hell's Kitchen, a roaring baby crying over proverbial spilled milk in one minute, and an utter behemoth bashing your brains in with a car door in the next. His inability to see the rabbit for the snowfield makes him not just one of the most compelling villains in all of Marvel, but one of the universe's most compelling characters, full stop. Kudos to Vincent D'Onfrio for an incredible performance.

And the winner is…

The Joker. Case closed.

Just kidding!

It's Loki! Loki's Number One!

You got Loki'd! You got Loki'd! You got Loki'd! Of course Tom Hiddleston's Asgardian is the greatest villain on the Marvel Cinematic Universe. Kneel and weep. No further questions, no further comments, case closed for reals.
