The Frogs are four brothers, who are anthropomorphic frogs, who steal to survive in a war torn dimension.
The Frogs were poor and untrained street fighters but relied on numbers and intimidation to steal to survive. One of the Frogs, Punk, spied on Winston Zeddemore and Leonardo in an abandoned building and assumed they would be easy marks. He noticed Winston's Remote Portal Access Band and thought it looked important enough to be worth money and stole it with his long tongue. Punk planned to sell it an owner of Battle Bots but Winston and Leonardo chased after him. Winston didn't want to shoot at him and risk damaging the access band. They demanded it back but Punk presented his three brothers. Glam demanded the Proton Pack. Grunge wanted whatever else they had. Metal wanted Leonardo's swords. Leonardo invited him to try and take them. He sliced Metal's cybernetic arm off then kicked him in the throat. He nailed Grunge with a left kick and offered his help but noticed Winston was holding his own. Winston punched out Glam with some boxing. Punk quickly apologized and offered the access band for Metal's arm. Winston angrily snatched the access band back. Before he could open a breach to another dimension, The Collectors arrived.
