Yu-Gi-Oh: The Abridged Series (often abbreviated to Yu-Gi-Oh Abridged or simply YGOTAS) is a popular fan parody of the Yu-Gi-Oh! anime as dubbed by 4Kids Entertainment. It is created by Martin Billany, better known by his screen name LittleKuriboh, who originally strived to update the series weekly, although this has not always been possible.^[8] The series has become incredibly popular with the number of visits to the main site ranking over 30 million. The show's increasing popularity has shown, with several new Abridged Series' being created for other shows, following the precedent set by LittleKuriboh.

Each "episode" of the Abridged Series parodies the original Yu-Gi-Oh! equivalent and is typically four to six minutes per episode (though episode length has steadily increased with time). The series is made using clips from the original series while voicing most of the characters and placing in sound effects, music clips, and other references to popular culture. LittleKuriboh voices all of the Abridged Series characters with the exception of Rebecca Hawkins and various other bit characters, who are voiced by his wife Abigail ("Abi"), better known by her screen name Safty.

Aside from "Yu-Gi-Oh: The Abridged Series", LittleKuriboh also has lent his voice to other abridged series, including "Naruto: The Abridged Series" (as Mako Tsunami and Yami Yugi) and "Dragon Ball Z: The Abridged Series" (as the Narrator), as well as in the machinima "Eden: The Zhang Chronicles". LittleKuriboh also voices Sugoroku Mutou in Project YGO's fandub of "Yu-Gi-Oh! Duel Monsters". He has also made cameo appearances in Kirbopher's flash animations Go Go Parody Rangers: The Movie as one of Evan Splooge's rat henchmen (who, in homage to "Yu-Gi-Oh: The Abridged Series," sports Yugi's hairstyle), and in Transformers: Revenge of the Lolin' as Seymour Simmons and Jet
