Sometimes I read online about how Magik is a hard character to adapt for other media. Which I find to be just silly. All you need to do, is to never show her as a six year old girl. Tell the audience that she is Colossus’ younger sister.
Also, she is one of those mutants with multiple powers – which is pretty cool. So all one has to do is explain that her mutant power is to teleport via disc that happen to go through Limbo. Which segues to what Limbo is, how she was trained there for a number of years or for some time – as years makes people wonder how she got there.
She is the ruler of that place – which, I’m not sure if you really have to say that – thus, she has awesome magical powers as she is a sorceress.
But that is even complicated, all you really need to do for Magik, is to have a young lady, with a Russian accent, with a soulsword and who teleports about the place.
Don’t even have to even use the word, soulsword, but that is what it is.
People, I believe, get hung up on the whole, on film – a young girl who gets teleported to a demon dimension, for seven years and now is the same age as the younger classmen and now is jaded and morose.
Of course, if they made a solo Magik film – which they should! – they could go into all of that but if she is just going to have a cameo or be used for a scene in a motion picture – she is super easy to adapt.
Even if they just had a young blonde lady who shouted, nyet! that could even be enough to let people know who she is.
