I found a previously undocumented Alpha Flight appearance from Oct 1994: issue #5 of Blackwulf. If youre all, "Who the Bendis is Blackwulf?", try this page for some info.
Marrina appears in 1 panel in flashback to the time she was an honorary member of the Avengers, a battle scene with the Kree Sentry android from Avengers #289.
When I get the chance, I'll scan in the image.
Love,
