Dark Evolution (SSJJ)

Overview
If the merger of a Dark Dragon Ball is defeated to point that can no longer fight while the Dark Dragon Ball hasn't been removed; dark energy will emit, causing their host to undergo a dark transformation into a further transformation.

Variations

 * Cell-X Transformation - Created by sampling the Dark energy from the Dark Dragon Balls, and intended monster for of Cell-X; Towa created this form in order to see what will happen if Cell-X went into his Cyro-Evolution only at 95%, and was disappointed by the results.
