The episode is famous for its high-octane team battles and massive scale, pitting the remaining warriors of Universe 7 against the colossal mechanical giant of Universe 3.
During the chaotic battle, Android 17 is blasted off the arena stage. In a selfless act of sibling bond, Android 18 leaps down, sacrificing her place in the tournament by throwing 17 back up onto the stage while letting herself fall out of bounds.
Following the strategies of Dr. Paparoni, the robotic fighters of Universe 3 combine into a single giant fusion entity named Agnilasa. This monster possesses overwhelming raw strength, high-speed echolocation, and the ability to warp space to throw punches through wormholes.
For the first time in a while, the remaining members of Universe 7—Goku, Vegeta, Gohan, Android 17, and even the villainous Frieza—are forced to perfectly synchronize and fight together to survive.
