I remember. In my world… the future I come from… you missed our little birthday meeting for decades. The villains had killed everyone else… so I figured you ticked off Red Skull or Doom or somebody one too many times, so they put you down. But then one day I picked up a scent…
I thought I’d seen all the horror I could possibly stand… but nothing quite prepared me for how you’d degenerated. You’d become what you were always destined to become… maybe what you always wanted to become… an animal. Except here’s what you’ve never understood, Victor. It’s not the animal part of you that makes you dangerous. It’s the human part. Without that, I put you down. Easy. Like a dog.
Wolverine and Sabretooth has this tradition where the latter tries to kill Logan every year during his birthday. Old Man Logan recounts the tale of how he killed his timeline’s Sabretooth. It turns out that a feral Sabretooth is less dangerous than a thinking Sabretooth.
