Depending on how much detail we'd want, we'd have to show:
His helping to catch Wolverine in UXM 120-121. (first appearance.)
Helping to hunt Machine Man (MM #1 while AF disbanded.
Rejoining a re-banded AF (AF #1).
Losing his mentor and fighting Deadly Earnest in AF #7-8. (Resolved in #…31?)
Quitting the team in the late teens; rejoining later. Slowly getting sick, until moving to Alfheim in #50.
Returning to Earth much later.
Coming out in #106.
Joining the X-Men and bumming around with them for a while.
Fighting Juggernaut (or did I make that up?)
Then leading X-Factor in their Puzzle Quest.

Sorry I didn't check all the numbers and go into proper detail. My collection is a whole foot to my left, and I don't want to go that far.
