Giant Ball

Monna demonstrated the Giant Ball transformation during the Tournament of Power, inflating her body into a massive sphere to overwhelm her opponents through sheer mass. In this form, she could roll across the arena at high speed, crushing anyone in her path, and her expanded body absorbed impacts that would have been damaging to her normal-sized frame. The transformation was effective against weaker competitors but ultimately proved insufficient against the strongest fighters in the tournament.

Vegeta's Response

When Monna targeted Cabba of Universe 6 with her Giant Ball form, Vegeta intervened to protect his student. Vegeta dealt with Monna's enormous form efficiently, demonstrating that raw size without comparable power to back it up is ultimately a liability against a truly skilled fighter. The Giant Ball form shares conceptual similarities with other size-increasing transformations in Dragon Ball, such as the Great Namekian and Gigantification techniques, but trades the humanoid shape of those forms for a pure spherical mass that maximizes surface area and rolling momentum.
