Quatro Cerberus appears to be an eccentric guild distinguished by a peculiar catchphrase: most shown members have the tendency to shout "Your soul will always be wild!" (魂はいつでもワイルドー Tamashī ha itsudemo wairudō) when encouraging fellow guild mates, which is followed by a "Fuoh!" (フォー Fō) cry. Some of them also sport spiked collars, similar to those commonly worn by dogs, in reference to the guild's theme, and the majority of them appears to consists of muscular men with a mildly punkish appearance.
The guild's location, save for it being in Fiore, is currently unknown. It appears, however, to be located in the same province as Fairy Tail and Blue Pegasus, due to Guild Master Goldmine's presence at the same regular meeting of Fairy Tail's Master Makarov Dreyar and Blue Pegasus' Master Bob.
Quatro Cerberus is currently led by Goldmine, who presumably created the guild or took its lead after leaving Fairy Tail. The guild has been active for at least some time before year X784, due to its veteran S-Class Mage Bacchus having fought Fairy Tail's S-Class Mage Erza Scarlet several times in the past, and is still active as of year X791.
While not as renowned as Fairy Tail (prior to the events of Tenrou Island), Sabertooth (following them) or Lamia Scale in the survey of Fiore's top Legal Guilds, and while portrayed as comedically weak several times during X791's Grand Magic Games, Quatro Cerberus has proven itself to be a group of powerful individuals: its team was indeed shown making it through the preliminary contest to the main event of the Games whereas 105 other guilds failed, and it even managed to best in position one of Fairy Tail's teams, made up by individuals such as Erza Scarlet and the S-Class candidates Natsu Dragneel, Gray Fullbuster and Elfman Strauss. In this context, Warcry's Tear Magic has been described as a noteworthy set of skills by Mages the likes of Sabertooth's Sting Eucliffe and Rufus Lore, and even by the former member of the Magic Council Yajima. What's more, the participating team was noted by Bacchus, the guild's only known S-Class Mage, to be composed of "young ones", hinting Quatro Cerberus to have stronger Mages at its disposal. Bacchus himself is a tremendously skilled martial artist, and his power was enough for him to fight on even terms with Erza Scarlet several times in the past; following Fairy Tail's 7-years absence, he's been acknowledged as much more powerful than before by both his long-lasting female rival and Fairy Tail's own Master Makarov Dreyar. Even the King of Fiore himself knows Bacchus, is aware of his reputation and eager to see him fight (though he considers the Twin Dragons of Sabertooth to be in a different league than him).
- Cerberus was a multi-headed dog in Greek mythology, said to guard the entrance to the Underworld. However, its number of heads was commonly acknowledged as three, instead of four ("Quatro", in Portuguese).
