Well everyone knows that Magneto only ever truly loved one woman - any that came after were usually due to youth or comparable beliefs - Polaris' mother springs to mind. Suzanna was a mutant (at least suggested in the comics anyway) who was trying to deny herself. When she met Magneto she was able to be a mutant - to just be herself - for the first time ever. But she still loved the man she was engaged to - and after a night of accidental romance with Magneto - when Suzanna discovered herself pregnant she left Magneto, quickly married her new husband, and only spoke to Magneto once more. Making him promise never to tell anyone about who or what she really was - and to stay as far away from Lorna as possible
Magneto's relationship with Suzanna matches up to Magda's fairly well - they both denied him and then left him out of fear (Magda out of scarring over the camps and loss of her family - believing Magneto to be a monster. And Suzanna clinging to her life as human) so Magneto's kids never really got to be around him when they were kids - not knowing him until they were older.
That said, they are still an important part of his life and I thought I'd post this here (and probably on the 'D later) to try and get some peeps to pick them up so we can have many plottings
as we've seen in the comics, Pietro admires his father - but is too laid back and 'frivolous' (as Magneto once called him) and often annoys Magneto more than helps him as he tries to solve a problem by approaching it solo... and only succeeding in annoying Magneto more when he actually manages to pull off a win! Wanda is the balance between her two siblings - able to speak to Magneto carefully and cautiously and help him find his center. The 'one with the heart' as she's been called, Wanda is cautious, maternal and loving and often goes out of her way to keep the peace between her family members. Lorna has recently come to agree with Magneto's more violent tactics and is suffering from power instability because of her mental problems caused by the horrors of what happened in Genosha. Of all of his children, Lorna has always been the one to side quickest with Magneto - especially now - and it would be interesting to see him trying to help her regain control of her powers.
Anyway, these are just plot bunnies *spooky voice* dooo with them what you wiiiiill
