Wolverine and Sabretooth share one of the most vicious rivalries in comics, the origins of which are enigmatic, even to Logan and Creed themselves. Nonetheless, they've inflicted great pain on each other numerous times over, especially given both character's healing factors, meaning they both can walk off wounds that would kill a normal human.

The more bestial and violent of the two, Sabretooth's acts tend to be crueler and unprovoked, so let's dive into the worst atrocities he's committed against Wolverine.

10 Broke His Claws (X-Men Origins Wolverine)

X-Men Origins Wolverine

2009's X-Men Origins: Wolverine combined Sabretooth with comics character Dog Logan, depicting him as Wolverine's half-brother who'd fought alongside Logan in wars for over a century. When the pair came to blows, Sabretooth came out on top in their first fight; to rub salt in the wounds, Creed stomps on Logan's pre-adamantium bone claws, breaking them in what was, judging by Logan's reaction, quite a painful experience.

9 Kidnapped Him For Weapon X (Hulk vs Wolverine)

The animated feature Hulk vs Wolverine is diverted from its titular premise halfway through by the arrival of Team X; led by Sabretooth, the group consists of mutants experimented on by Weapon X contracted to recapture Wolverine after he escaped the program's captivity. While Wolverine once again escapes Weapon X's grasp by the film's end, it proves to be a painful experience, in no small part due to Sabretooth.

8 Crashed His Wedding With Viper

One of the most unusual directions Wolverine's life was when he was blackmailed into marrying one Ophelia Sarkissian, aka Viper, aka Madame Hydra. While Logan wasn't happy with the arrangement himself, Sabretooth set out to ensure his enemy extracted even less joy from the occasion then he would've otherwise.

Sabretooth attacks the wedding, injuring Viper and overpowering Wolverine, forcing Kitty Pryde to escort both the bride and groom to safety with her intangibility powers.

7 Ruined His Life In Inuit Village (X-Men 1992)

Sabretooth X-Men Animated Series

In the 1992 animated X-Men's first season, Wolverine, realizing his feelings for Jean Grey will remain eternally unrequited, leaves the X-Men for Northern Canada. Settling down with a local Inuit tribe, Wolverine finds peace for a time, but it turns out Sabretooth has pursued him and is seeking vengeance for an earlier defeat. Wolverine manages to save the villagers, but the village itself is destroyed in the process, forcing him to semi-reluctantly return to the X-Men.

6 Lied About His Parentage

Chris Claremont had intended Sabretooth to be Wolverine's father; he never got the chance to introduce this idea into Marvel canon, but Larry Hama would allude to it during his run on Wolverine. During a confrontation in Wolverine #41, Sabretooth drops the seeming bombshell that Wolverine is his son, but Logan refuses to believe the claim. A DNA test conducted by SHIELD proves Logan right, but the thought that his greatest enemy, who's caused him so much pain, could've been his father was mental agony for Logan, no matter how quickly it passed.

5 Killed Feral

X-Men '90s Villain Feral

Sometimes, you don't have to directly hurt someone to inflict pain. During the Evolution storyline covered in Wolverine #50-55, Wolverine was leading a team of mutants, consisting of Feral, Sasquatch, and Wolfsbane to apprehend Sabretooth. Tracking him to an abandoned Weapon X facility, Sabretooth overpowers the whole team, but does something particularly gruesome to Feral.

Creed, rendered animalistic by increased mutations, kills Feral and eats her remains. Appalled the gruesomeness and with her death on his conscience, Wolverine uses the mystically-enchanted Murasama Sword to decapitate Sabretooth, seemingly killing him for good.

4 Burnt Logan's Past (Ultimate X-Men)

Ultimate Marvel changed several aspects of the classic 616 continuity, but the set-up of Logan and Creed's relationship was practically identical to the original versions; they both shared a history in the Weapon X program and a visceral hatred for each other. In the 2nd arc of Ultimate X-Men, when the X-Men are abducted by Weapon X, Sabretooth inflicts a particularly brutal bit of psychological torture on Wolverine; knowing Logan is haunted by an inability to remember his past, Creed burns the only copy of a file containing the truth to Wolverine's past.

3 Birthday Boy

This isn't a single act, but a sick tradition for Sabretooth. Once every year, specifically on Logan's birthday, Creed will track him down, wherever he is (taking advantage of his advanced senses) and inflict some pain on Wolverine, whether it be a simple beating or something more twisted. No matter what he chooses to do, the tradition ensures that Wolverine's birthdays are far from a happy day for Logan himself and any of his loved ones who are unfortunate enough to be on Sabretooth's radar.

2 Killed Silver Fox

Here it is; the event that began the aforementioned way that Creed commemorates his enemy's birthday. As chronicled in Wolverine #10; in the early 1900s, Logan was living in Canada with Silver Fox, a young Blackfoot woman, before she was murdered by Victor Creed on Logan's birthday. Confronting Creed about the death at a nearby bar, the future Sabretooth beat Logan, and thus the tradition was born.

Future stories have cast doubt on whether Silver Fox's death happened as depicted in the original tale, suggesting it may have been simply an implanted memory in both Logan and Creed's minds, especially since Silver Fox turned out to later be alive. However, as Logan himself put it, the anguish he felt from the death was all too real.

1 Manipulated Him To Kill Daken

Sabretooth described this as his master-stroke, and from his sick perspective, its not hard to see why. Daken was Wolverine's son, born from Logan's marriage to a woman named Itsu, and the boy inherited his father's mutant abilities, but none of his morality. In an attempt to gain revenge on his absentee father, Daken teamed up with Sabretooth to form a new Brotherhood of Mutants, and the group's battle with X-Force culminates in Logan drowning Daken, intercut with shared imaginations of the life they could've shared. Just as Daken takes his final breath and Logan mournfully holds his son's body, Sabretooth appears on the scene, revealing this had been his intention since he first partnered with Daken. The greatest pain Creed has ever inflicted on Logan, and he didn't have to lift a finger himself to bring it about.
