Rulgore is a free world.
Around 5 Million Before Age, Bibidi and Majin Buu came to this planet. The Supreme Kais had gathered up all of the greatest warriors remaining in the universe and had sent them to destroy the duo. It was on this world that that battle took place. Majin Buu fought all of these warriors by himself, and after a long battle that took the better part of a day, he destroyed them all. Afterwards, Buu fell asleep on Rulgore for about a day before Bibidi coaxed him awake with some candy. Afterwards, the pair moved off to Planet Alpha, leaving Rulgore, now devoid of life, intact.
In Age 749, space pirates bombarded this planet, reducing its native population to zero. It was assumed that the planet had been a trade hub prior to that. The nearby spaceport, Boson Station, took in most surviving refugees. Some months later, during Across the Universe, the astrobiologist Kage hired Udon and Soba to take soil, water, and air samples to see if any lifeforms had survived the orbital bombardment.
The Yardrats went to the planet's surface, but they were soon met by Master Xutol, who invited Soba to join the Venyi Academy. Udon completed the sampling by himself after Xutol and Soba used Instant Transmission to return to Xutol's school.
- Some life did survive the space pirates' assault, as during Udon's recon mission, he found at least one species of underwater fish still living (though he killed the only specimen he found).
- Rulgore's native population:
- At height: 14,820,177.
- At lowest point: 0.
Rulgore is still around.
