Victory at a Price

The hero manages to defeat a villain, but all of a sudden, something horrible has happened that makes this victory out to be a curb stomp defeat. Victory at a Price is a rare but a tragic yet sometimes an intense event where the hero emerges victorious, but there happens to be a catch. This can happen through other means, such as a villain all of a sudden survives and physically kills the remaining people, and among other instances.

Examples

 * After Future Trunks and his allies emerged victorious, but, Fused Zamasu manages to survive as an ethereal spirit and violently destroyed the entire city and murdered all of the mortals except for Son Goku and his team. The worst part is that Infinite Zamasu is beginning to spill into all of the timelines and the rest of the cosmos, especially the present timeline of Universe 7, at least almost.
