Is it the one that involves Astra cloning Magneto for the first time (spawning Joseph)? Or is there something else? I need help! :p

If there is something inbetween Joseph and FA, then I'd like the story arc involving Joseph's creation as well. Thank you!

I think its an xmen/avengers crossover called Bloodties but im not for sure. Ill look it up

@hart7668:

"The Phalanx Covenant" is the crossover that is in 1994. It's the crossover that sets up the Generation X spinoff

Try this one....

Origin, cloned by Astra...........
