My only surprise when I saw Thanos up on the screen was how violet he was. I always saw his exposed hide as being more grayish violet.
Back in my high school years, the Hulk was my favorite Marvel character, and I always enjoy drawing him.
I got rid of Warlock's lightning bolt because... it was a real pain to draw.
There's a character, Eon, I did back in the 'Captain Marvel' story. Eon came from a greasy smudge on a paper bag inside my kitchen being used for garbage. I went and got a paper and pencil, drew it up, and he became a character in that story. Things come from everywhere.
When I was a kid, there was this neighborhood beer and wine store that sold old comics for a nickel a piece. I'd load up on old books whenever we went on vacation. Yeah, I have a lot of fond memories of riding in the back of the ol' station wagon and reading 'Mystery in Space' and 'Strange Adventures' as we headed up to Torch Lake.
Thanos and Adam Warlock are two of a kind because they're both sort of out of the norm: out of the circle of life and death that falls on top of everyone else. Both have had multiple deaths and resurrections, and they always seem to get pulled in as key players for cosmic events.
