Cell Jr.

Cell spawns seven Cell Juniors during the Cell Games specifically to brutalize Goku's allies in front of Gohan, hoping the sight of his friends' suffering will push the young half-Saiyan over the edge. Each Cell Junior is roughly as strong as a Super Saiyan, making them capable of fighting Vegeta, Trunks, Piccolo, and the others to a standstill. Their relentless assault does succeed in enraging Gohan, though it is Android 16's subsequent death that truly triggers Gohan's Super Saiyan 2 transformation.

Once Gohan achieves Super Saiyan 2, he annihilates all seven Cell Juniors with casual ease, demonstrating the enormous power gap between Super Saiyan and Super Saiyan 2. In Dragon Ball Super manga continuity, it is revealed that some Cell Juniors actually survived and now live peacefully on Monster Island, working as park rangers. This unexpected twist gives the formerly disposable minions a surprisingly wholesome second life and expands on the idea that Bio-Android creatures are not inherently evil, merely products of their creator's will.
