Bargingo

Bargingo was the first ever shadow dragon ever created, even before Shenron. He has ultimate power.

His power level exceeds above xenosamas power level.

Because of his powers, the gods of destruction teamed up and split Bargingo into the seven dragon balls and the seven black star dragon balls.

Once someone gets all 14 of the dragon balls they can summon the all mighty being that is Bargingo and they'll grant any wish.

Although this comes with a price of Bargingo becoming free from his imprisonment and destroying the entire galaxy.

Abilites
Darkess Mixer:  He controls the darkness of the void and traps his foes into a vortex for all eternity. The vortex emulates the feeling of death as the person trapped in the void will experience himself dying over and over again for all eternity.

The battle cry of despair:  Bargingo opens his mouth very wide and does a funny scream.

Genetic Breaker:   Bargingo surrounds himself with an energy field and anyone who happens to stand in said field will have their entire being dissolved slowly over a period of 2 hours.The enemy may try to use this time to attack Bargingo, should their very being be powerful enough to hold it out for two hours under excruciating pain, but by this point Bargingo's power level is too great for any being to comprehend making it impossible for a weakened enemy to even make a dent in Bargingo's defenses. Rreze e vogël:   Bargingo shrinks his opponent to be exactly six inches tall. Once he has shrunk his opponent down he then transports him into a white room with no doors and no open windows. This tortures his opponent as there is no way out of this room, making them trapped in this room for all eternity.
