ideal cross-canon CR for Popp

I want him to hang out with Sokka Avatar because they are both incredibly smart and incredibly stupid in various areas that overlap a little but spread out enough to give them both terrible new ideas for how to help a twelve year old defeat an evil king

They should go on an adventure together and talk about boomerangs and girls and having an inferiority complex

Holy shit

Popp doesn't have boomerang proficiency but he did work in a weapons shop in dragon quest. He knows a good 'rang when he sees one
