Like the rest of the Fearsome Foursome-Sergeant Simian, Predator Hawk, and Lightning Lynx-Flying Frog debuted as an agent of Mammoth Mogul's, attacking the Chaotix on his orders. After being defeated and retreating from this battle, he would return to help Mogul in his bid to claim the Sword of Acorns by pitting the Chaotix and Freedom Fighters against each other. Frog's purpose involved serving as the substance behind Mogul's illusions of Vector the Crocodile and Sonic the Hedgehog, which initially had the two groups fighting. When the more level-headed members of each team noticed the errors in these illusions, however, the scheme was blown and Frog was captured along with his teammates. (SMM, SSS: #1)
