I think I stayed close to the rules using Canadians but non Alpha Flight characters except one.
Puck-The real leader but with a criminal background he doesn't get the official tile.
The original Major Maple Leaf-The figurehead and spokesperson with some political power. Puck and MML have history that’s never been told. Would make for some great one off stories. Sure he's old but he certainly held his own against Northstar.
Night Raven from Marvel UK - The “Wolverine” of the group...cool underused character. Hails from Alberta.
Wendigo- A young native women who learned mystic skills that helped her control the curse. She is constantly learning more about shamanism to find a cure. Gets the team in loads of trouble as a result. OK I made up the back story but Wendigo is such a open-ended character these days I couldn't help it.
Kadlu-goddess of lighting.... We could use her powers in interesting ways...speed... Transports herself or others thru electricity. Our speedster with offensive capabilities as well.
Dept H or K provides the technology and support like in Steven Seagle`s run and somewhat like what Shield does in the TV series. If we couldn't use a government department we could easily explain the older characters like Night Raven, Puck and Major Maple Leaf acquiring maybe a quinjet or transportation ring and other hi-tech over the years. A great way to tell back stories of these characters.
I think with Dept H we could introduce some cool technology... and with Puck, Wendigo and Kadlu we keep enough of a mystic element that always been an important element of the Flight.
