Vs The Pack
Seeking to strengthen their newly formed alliance, Slade decided to call in his deal with the HIVE Academy, gaining the services of their top students, Gizmo, Jinx, Mammoth, See-More, and Private Hive, otherwise known as the HIVE Five. Placing them under the leadership of Negaduck, Slade decided to test their abilities by sending them to take down a group of assassins known as the Pack, consisting of Fox, Wolf, Dingo, Jackal, and Hyena. The group confronted the Pack at their studio, getting their attention by causing a bus to crash nearby. As Jackal and Hyena attempted to attack them, Private Hive knocked them back with a blast of water. Seeing what they were dealing with, Fox mobilized the group to take down their foes. As Gizmo advanced, Dingo downed him with a boomerang. Wolf rushed at Mammoth, but Mammoth proved to be the stronger of the two and caught his punch, allowing Jinx to send Wolf flying with a blast of magic. Seeing their allies fall, Fox and Dingo attempted to come to their aid. However, Negaduck blasted a hole through a wall, burying them in rubble. Finding themselves outmatched by the super-powered teens, the Pack retreated, much to Negaduck's pleasure.
