little old guy who’s paradoxically, extremely dangerous

Oh I see, you mean like the little chinese grandpa who turns out to be a grand master of kung fu when he is getting attacked.

And I kind of like it, frankly! You know, as opposed to the more common ‘look at me, I’m muscular and badass-looking’ character, which is kinda what Marvel/DC have flogged to death over many decades.

Absolutely, it´s a reason why John Difool is my favorite sci-fi hero!

So an artist might create half-a-dozen odd character designs to show the production-designer / director, letting the boss pick and choose elements they like best to create the final physical version of that production’s character. All very SOP and common in these cases. So you might even find a concept drawing in which Duncan is the shrimp, and Gurney, the big, imposing guy.

Makes perfect sense to do several different drafts to select the best one in the end, I did not think of that practice.
