The Super Seventeen War

This battle is set in NG. It is the least changed saga that survived revision.

Backstory
Seventeen is revealed to be running out of anti-psychotics. In time he begins killing humans without cause, disquieting the Saiyans.

The tipping point came when Seventeen murders Alex Ryder. Seeing as he had no intentions to stop, the Saiyans gather to confront Seventeen. As they sought to encounter him, Eighteen turns on the Z-Fighters and staves them away from her brother in a low-scale conflict. Now positive that Seventeen was beyond them, Vegeta takes Trunks and appeals to the Saiyans
