So, every gen I do a nuzlocke-ish theme run. (Follows most nuzlocke rules except I catch some extra pokemon per route, but box them and don't use them until post game for competitive breeding. And I store my "dead" pokemon in a seperate box instead of releasing them. Again, in case i want to competitively breed them post game.)
Since third gen, I've done:
Romeo&Juliet
>Mercutio, Benvolio, Romeo, Juliet, Tybalt, Paris
Titles
> Dr.Thunder, Mr.Krabs, GnrlPepper, Cpt.Crunch, Czar Mie, Dr.Octopus
Superheroes
> Thor, Starfire, Robin, Beast, Batman, Aqua Man

For this, I was thinking of my favorite musicians. Definitely inpired by the anon who posted the female litleo evolution as beyonce. Copping that shit because it's gold. What about this guy? 2d? Who should I give this name to? Doesn't matter what gen the pokemon is from. I'll go to any lengths as long as the fit is right.
