Living Star (Los)

Los is the embodyment of a living star, featuring within the New Dragon Ball Manga. He formed upon a reaction with an alien particle colliding with a star particle, forming an entity similar to a black hole, sucking up life from the universe. Upon accidentally merging with a Super Dragon Ball, Los gains a life-force and conscious.

With no sense of purpose or direction, Los wanders for another one of it's kind, eventually ending up close to Earth. Los's destructive aura disturbs the Earth's atmosphere and plunders it into darkness. Bulma investigates the matter, leading Vegeta to the source. Equipping Bulma's new Space Saiyan Battle suit, Vegeta voyages into space to confront Los. Frustrated by the negative force emitting from Los, Vegeta launches a ki blast which angers the living star.

In the end, a positive wish causes Los to calm his aura and make peace with the inhabitants of Earth.

Power
Los gains matter from the space particles around him, meaning he will keep absorbing matter and keep growing in power. When encountered by Vegeta, Los was weaker than Super Saiyan Vegeta but was able to escape. Whilst away, Los manages to absorb one of the six suns of the universe, gaining enormous energy! He recounters Vegeta and Goku and effortlessly defeats them.
