This was tough between Kitty and Jubilation. I personally enjoyed reading about Logan and Jubilee, but to each his or her own!
2. Kitty Pryde
The original sidekick to the Wolvster.
If you haven't ever read some of the early X-men with Wolverine and Nightcrawler then you should try to! Great stories and Logan teaches Kurt to accept who he is and not to allow what people say about his looks get to him. Of course that's easy for Logan to say... he's not a blue and fuzzy elf demon!
I enjoyed their tussles in Madripoor.
The cajun was a good teammate to have around when the dealing's done.
Wolverine/Havok: Meltdown.... great story!
Although they fought... a LOT. I remember some good stories with Logan and the grey Hulk in Vegas back in the early 90s.
8. Heather McNeil Hudson
She helped "tame" the wild-side of Logan long before Jean came on the scene.
9. Tyger Tiger
I was really excited to see a female bartender at the end of the Wolverine movie... Was this THE Tyger Tiger who owned a bar in Madripoor? If so, then Hugh Jackman has already started off on the right foot for the next movie! Tyger was a really cool cat who may have been more than just a name in "Patch's" life.
This is more future partnerships than past. Their lives are tangled together forever...
