Things come and go in the comic world as you know. No one seems safe from the blowing winds of editor's needs to reinvent the wheel.
Take Deathstroke (wrong company but a great example), only a few decades ago he was a semi-pedophile (his relationship with Tara) and an attempted child murderer (Judas Contract), yet just a few years later he is part of a superhero army (Panic in the Sky) bent on saving the world recruited by Superman himself.
Comicvine put it best by describing him as "Deathstroke can be a "violent gun-toting mercenary, unafraid to kill", a likable anti-hero, or just another hired gun meant to fill in the pages. "
Could Doom, Magneto, Loki all not fall into this swinging pendulum.
How many characters from both companies have been played this way, like ping pong balls bouncing at the will of the latest trendy author.
Hero-Villain-Hero-Villain....Hero again.........for now.
