I'v read very little of the ultimates comics, actually i've only read like 2 issues of the ultimates. I would have kept up, but i lost track of the series to keep track of other comics that caught my eye. My question is if someone could explain a little, about how they have portrayed the hulk in the ultimates comics. Is he in alot of issues, if so is it worth investing time into reading. Also is he always grey when he transforms or has he ever gone green? (any pics anyone can post?) cause if it's worth it, then i think i will start collecting the issues. thanks for any help.
