There isn’t a direct or routine path to roles like that.

Anything not Stickfigure based ( Stickfigure badges ) will usually require a specific set of conditions and requirements to be met in order for it to even be in consideration.

Just as some general advice towards creating your own stories or characters, it’s best not to imitate or copy anyone else’s work, being inspired is fine but imitation can just seem very low-effort and kind of embarrassing to some extent.

My point here is this is very reminiscent of Joker Execution, the name, design and more is very similar and overall you’re better off doing your own thing.
