About the small birds. I was suggesting birds that fly swiftly. ex. Sparrow, hummingbird & swallow.

That can be for a female OOO like Hina.

Maybe a Roadrunner?

City Vermin!
A copper colored set of Medals themed after the Rat/Nezumi, Pigeon/Hato and Cockroach/Gokiburi and grant OOO with hightened intelligence, defense and an array of initially weak but potent "pestilence attacks" that are basically status moves from Pokémon.

And that's as far as I got because I can't make a pun out of those animals' names for a theme tune.

Perhaps I can be of assistance!
Nezumi, Hato, Gokiburi. Hmm... NezHaGoki? Perhaps the ending song can be "Never Go Kill"? :D

Thank you! And without further ado...

Combo Name: NezHaGoki
Animal Type: City Vermin
Medal Color: Copper
Medals-
Head: Nezumi (Rat)
Body: Hato (Pigeon)
Legs: Gokiburi (Cockroach)
Theme: Never Go Kill
Henhin Tune: Nezha nezha nezha, NezHaGokiiiiiiiiiiiiii!
Combo Hissatsu: Infestation. Various creepy crawly pests start crawling down from OOO's waist until his legs are just a column of swarming vermin sprouting out of of a sea of swarming vermin that overcome and devour enemies.

Greeed: Gaichu
Name Meaning: Vermin
Elements: Trash
Yummies: Litter
Gender: Male
Human Disguise: A seedy, unkempt motel owner in a cheap brownish-orange suit that looks like it was made from that ratty old rug in your Grandma's basement.
Story: Gaichu wants to be complete, like all Greeeds. But Gaichu's different. He wants everyone to be complete with him in the rancid duchy of trash and vermin that is his ideal world. No matter how many ordinances he receives for his motel's health violations , nothing will stop him until he is the Duke of Trash.

What do you think of these? And how would you make them song titles?

- IkaShiGa (Deer, Bull, Gazelle)
- KoaHejiRu (Koala, Hedgehog, Kangaroo)
- MauBaaRi (Mouse, Beaver, Squirrel)
- RokuHyoGin (Polar Bear, Snow Leopard, Penguin)
- KaeHikiSho (Frog, Toad, Salamander)
- WaGuiZaru (Harpy Eagle, Anteater, Spider Monkey)
- KoMoRai (Bat, Mole, Raccoon)

I love the idea of RokuKyoGin.

I found this of the reptile greeed. Her name's Nageen: http://dezet08.deviantart.com/gallery/42732869

Got any more greeed & core medal ideas?

Does anyone still have greeed in mind?

RokuHyoGin could be "Rouge Shogun" KoMoRai could be "Come on, Ride!" KoaHejiRu could be "Go Ahead, I Hear You" MauBaaRi could be "My Body" and WaGuiZaru could be "Walking Tall."
