There was a time when Lobo was one of the most popular DC characters of them all. Fans loved his irreverent attitude and ultra violent adventures. In fact, it's safe to say that without Lobo, Deadpool never would have happened or at least not the Deadpool fans have grown to love. Lobo was the blueprint for a new type of anti-hero.

He was also easily one of the toughest DC characters of them all, able to shrug off blows from Superman and survive planet destroying attacks like they were nothing. He's functionally immortal, since only another member of his race can kill him and he's already killed all the rest, and has a high octane healing factor. If Lobo went up against some of the greatest villains of the Marvel Universe, which ones could he beat? Which ones would beat him?

10 Would Defeat: Sabretooth

Sabretooth Ravencroft feature

Sabretooth is known for being an irreverent killer and he and Lobo have that in common. Both of them have been known to work for the highest bidder, as well. Both are great fighters but Lobo has a huge edge in strength and that means he easily beats Sabretooth.

Sabretooth is tough but Lobo is a guy who has been known to fight Superman to a standstill. Against someone like that, Sabretooth has exactly zero chance of pulling out a victory.

9 Would Lose To: The Celestials

Lobo's immortality and amazing healing factor mean that it takes a truly next level power to destroy him. Most villains wouldn't even be able to phase Lobo, so a more powerful approach is called for. Enter the Celestials.

The Celestials are massive space gods, responsible for life on multiple planets around the universe. Their armor is nigh impenetrable. Lobo would keep throwing himself at the Celestials and they'd barely notice. Eventually, though, one of them would just reduce him to atoms and that would be that. He technically wouldn't be dead, he would just be discorporated.

8 Would Defeat: Green Goblin

Spider-Man's greatest foe, Green Goblin is a formidable villain. He combines, brains, brawn, and insanity in a delightfully entertaining package... and he'd be able to do exactly nothing against Lobo. Less than nothing, really.

Green Goblin is strong, smart, and well armed but nothing he can do would have an effect on Lobo. This would just make Goblin madder and madder... if Lobo even let the fight go on that long. Not only can Lobo shrug off Superman's strongest blows, he's also strong enough to hurt Superman. He could take down Green Goblin in a single shot if he tried.

7 Would Lose To: Molecule Man

One of the most powerful beings in the Marvel Universe, Molecule Man has complete control over all matter and energy. Luckily for the heroes of the Marvel Universe, he's such a bed of simmering neuroses and mental problems that he doesn't really try and win fights.

Lobo is a titan but against someone with complete control over all matter? Yeah, there isn't much that he can do. Lobo would come at Molecule Man and Molecule Man would transform him into oxygen or something before getting back to his nervous breakdown.

6 Would Defeat: Ultron

Age of Ultron feature

One of the most dangerous villains the Avengers have ever faced, Ultron's biggest advantage against Lobo is his adamantium shell. This would help him survive in the fight for a while but he couldn't really hurt Lobo- he's just not powerful enough.

Lobo would be pounding Ultron harder than he'd ever been hit before and that's actually a huge problem for the mad android- his exterior may be near indestructible but his internal components have always been a lot less durable. The kind of hits Lobo would be handing out would affect those components and that would spell doom for Ultron.

5 Would Lose To: Dormammu

Dormammu is the ruler of the Dark Dimension and has legions of demons at his disposal. He'd start things out by sending those against Lobo. Lobo would singlehandedly decimate all of Dormammu's armies and Dormammu would realize he would have to deal with the Main Man himself.

Lobo would put up a great fight against Dormammu, but it takes more physical might to beat someone who is as powerful as Dormammu. It would take Dormammu a little bit but he'd eventually figure out a way to take Lobo down.

4 Would Defeat: Loki

The God of Mischief, Loki is used to dealing with powerful enemies but he's not ready for someone like Lobo. Loki likes to use his magics to trick his foes but Lobo's willpower is pretty much indomitable- his mind can't be controlled. While his other magic may be able to hurt Lobo, he wouldn't be able to put Lobo down.

Loki is no slouch in the strength department, but Lobo outclasses him by a lot. This is another case of just plain not being powerful enough to hurt Lobo. Loki's magic is strong but it's just not enough to stop Lobo before he can take Loki out.

3 Would Lose To: Galactus

Galactus and Lobo have a lot in common, strangely enough- both are genocidal threats that have destroyed whole worlds- Galactus because he's hungry and Lobo just because they angered him. Both are extremely powerful and have smacked around some of the greatest heroes of their respective universes. Both are very hard to beat.

Lobo's attacks wouldn't really phase Galactus at all but eventually Galactus would get really annoyed with Lobo and take action. Galactus might not be able to kill Lobo but there's lots of ways that he can hurt Lobo and would be able to easily defeat the Main Man.

2 Would Defeat: Thanos

Thanos is one of the most dangerous and powerful villains around but Lobo would be able to take him. Lobo has been shown to knock out Superman with one hit. Thanos is strong but even he would fall to strength like that. Of course, Thanos has lots of other powers, though none of which would help against Lobo.

Lobo's invulnerability, combined with his healing factor, makes him just about unbeatable. As powerful as Thanos is, he just can't beat someone who can regenerate from a drop of blood and keep the fight going. It would be a battle of attrition, but one Thanos would lose.

1 Would Lose To: Doctor Doom

Doctor Doom

On paper, Doctor Doom shouldn't be able to beat Lobo but Doom has made a life of defying the odds. He's one of the most intelligent men on the planet, a master of magic, and has what is probably the most formidable suit of armor around, able to drain the power of cosmic beings. He'd need all of that to win.

Doctor Doom would use Doombots to gauge how powerful Lobo was and come up with the perfect countermeasure to defeat the Czarnian bounty hunter. It would be costly but Doom would triumph.
