After a long debate, I decided to rework Chirper's character to become a free bird. 'cause that's how pimps live cool
Of course, Chirper - permanently being a swablu - will need a trustworthy gang to help him survive on the streets and assist him in stealing shiny things from the random unsuspecting citizens of Zatao!
...I totally need to make a journal for him when I have time BUT...
Basic Background: Chirper originally served the Katarina gym leader for a short while before deciding to take off on his own - he didn't find it as fun to have to follow around a single person constantly. Especially when that person kept saying he couldn't steal any shiny objects from gym challengers!
So now he hangs around the streets of Zatao, looting random shiny things and hoarding them at the gym. Even though he no longer is part of Luna's team, he still takes full advantage of the protection they give him from Luna's lingering affection towards her old pokemon. No one dares to steal his loot at a gym building!
Chirper may be willing to grudgingly help along a new bird or two learn to run the ropes around the city - he has been hanging around it for a while now. In exchange for his guidance and shelter (he'll help members sneak into his hide-out in the gym and Luna will be baffled as why there is so much more bird poop around...), he expects to get part of any loot the members of the gang steal. Think of it as a rent of sorts.
But you know, fellow bird pokemon have to look out for each other. There are so many pesky electric mouses trying to show them up in the food chain and bird feet could very well become the next delicacy served in Katarina's high-end restaurants! So if you have a wild bird pokemon, he/she should totally hang out with Chirper ;D
Just remember that the gang will mostly stay in the city because that's where most of the shiny stuff is.
TLDR:
-BIRDS ONLY
-CHIRPER IS A PIMP
-YOU MUST GIVE ALL UR SHINIES TO CHIRPER
You may also throw around RP ideas about Chirper here ovo b

Also getting into a battle over it sounds fun as well!
