When They Kill off or mis use or Under use a Character I dearly Love:
Illyana Rasputin
Karate Kid
Colossus
Insert your fav. Character here
I simply create an alternate reality in which that character lives on, either with a similar character I create or as themselves. ( I prefer to use my own characters , mostly. )
Comics are from the imagination. So I imagine my OWN comics. I have 40 characters. I put them in stories of my own, either when I cannot sleep, or at the dentists, or when unpleasant thoughts overtake me. I would not want to try doing it for a living, THAT good I ain't..But it beats mourning the loss of a special character that you've gotten to know care about.
Under Clairmount, Illyana was special.I miss her.
I brought Back those from the 60's. Prince Planet. The heroes from Space stars - Kid Comet, Elektra and Moleculad.
Used to actually draw the adventures but that got tedious.
That way, they sometimes come back. And it's like in a Way, I never lost em.
