From Dragon Ball Wiki, the ''Dragon Ball'' encyclopedia
The evil dragons, known as
Shadow Dragons are evil beings created by the overuse of the Dragon Balls over the series and are the final 7 antagonists of the
Dragon Ball series, there is
Haze Shenron,
Rage Shenron,
Oceanus Shenron,
Naturon Shenron,
Nuova Shenron,
Eis Shenron and
Syn Shenron (becomes
Omega Shenron when all dragons combined). They are eventually all defeated by
Goku, except Nouva Shenron who was killed by Omega Shenron. Of the seven, only Nuova, Eis and Syn Shenron are capable fighters. Nuova Shenron is believed to have the least negative energy out of the Shadow Dragons, due to his morals and the wish that created him. (Most of the other dragons were made by very selfless wishes, whereas Nuova's was a very selfish wish made by King Piccolo when he wished for his youth and power to be restored.)
