Let’s learn how to draw Saitama from One Punch Man today! Saitama (????, Saitama) is the main protagonist of OnePunch-Man, and the most powerful hero alive. Having apparently trained himself to superhuman conditions, Saitama faces a self-imposed existential crisis, as he is now too powerful to gain any thrill from his heroic deeds.

Thanks a lot to JonathanMustang for request. ^^
As always all the blue and green lines are just construction lines and will be erased later so do not push on your pencil too much ^_^ I will try to be super efficient with text so will only describe steps that require some explanation.
Make sure to leave enough free space on paper for next steps. You can see how much space you will need from the size of the paper on this picture.
Lighten all the construction lines by "stamping" the kneedable eraser on paper. Make sure to refer to the picture above as you need to ink only some parts of the construction lines. There are also some new lines so better sketch them in pencil first ^_^.
Wait till the ink is nice and dry and erase all the construction lines.
To add colors, make sure to sketch the color outlines with the right color or pencil first.
