About
Onion-Tou (also know as Onion Head, Onion-kun, or his official name Abo) is an anthropomorphic, hyperemotive onion created by Taiwan artist Ethan Lui as part of a series of characters collectively called The Onion Club.
The Onion Club, as of May 2011, consists of four characters: Abo, Meiya, Greaser and E (pictured above, from left to right). Abo, however, is the character that is depicted the most frequently, having a near monopoly not only on fanart, but on the official Onion Club icons as well.
Onion-Tou, much like Pyong and Tuzki, is also a conspicuous character on the art website deviantArt, with over 100 PLZ icons (most of which seem to be direct copies of icons from the Onion Club site) and thousands of Onion-Tou fan images.
