Just some enemies that could appear in Kamen Rider N. Above villain/monster of the week: Mouser, Crazy Redd, and Onox.
Below: Goomba, Bokoblin (tried to mix the different versions of bokoblins in this one), advanced minion Shyguy, Octorock.

So what are the villains of this series after? I have no idea. I got other things to focus on.

Will be scrapped later.
