It was a black Copic Ciao marker. Yeah, expensive <_< (well, it's like 5 bucks for one)I just used it because it came in a set... yeah, even more expensive <_<.
There are brush-tip markers and pens that are much cheaper and actually the ink on those are darker and blacker (and don't fade) than a black Copic marker. I have 2 Faber Castell pens that I use that don't smudge/bleed when you color over it with a Copic marker, so the ink on a Faber Castell is alcohol-proof and waterproof (as it says on the pen).
I don't have any of those poseable mannequins. I don't feel that they realistically represent human anatomy, and they are not that poseable. I've drawn enough figures using guidelines and 3d geometric shapes that I can usually draw a figure and work it out from memory and adjust to make it look right.
When I do need a reference, I either look for a photo or take one, or even look at another artist's work from a comic or something.
Or, I use a Super Poseable Spider-Man figure from the Spider-Man 2 movie's action figure line.

But his poseability is pretty impressive... I think it's the first time where I've seen an American action figure where you can move the shoulders forward and back.
What's weird is that the current version of this toy has magnets in his hands. I feel kinda gipped.
