Lignen Hammil "Little Guy" Gunpanow, (better known as Little Guy and formerly known as Big Guy), is the main protagonist of Greeny Phatom, Greeny LOL and many other Greeny Phatom-related shows. His birthday is on March 2. He once led the Anti-Gree City Army with had a lot of Greeny Phatom characters (especially Santed Sailor), as well as those from World of Jake, Luke City, Finley's World, and the Baxter Bros and more (except Gree City) in Greeny Phatom The Movie 3. He is voiced by series creator Robert Stainton, which is somewhat disappointing because he doesn't deserve the job while the other voice actors do because he sounds somewhat old. Little Guy hates shows such as Gree City, The Buneary Show, and Bryan's World. He likes shows such as Greeny Phatom, (of course he likes that show), Punic Circle, and other Greenytoons.

He is a minor character in MYCUN.
