He is a crazy psychopath who does nothing but kill. He destroyed the entire Northern Galaxy except Earth, because that is were he wanted to live. He is confident that no one in the universe or anywhere can defeat him, although he was proven wrong when Gogito defeated him.
Right after escaping Hell, Bio-Broly and Broly took off for Gohan to tell them where the Potara Earrings were. He told them after they badly beat him. After they fused, Bio-Broly and Broly, he destroyed all the Earth's special forces, except Gohan, his family (not counting Goku, and Goten ), Bulma and her family (not counting Vegeta, and Trunks ). He even killed Yajirobe, Tien, Chiaotzu, Yamcha and Puar. He let every one else live to be his servants. He destroyed the entire North Galaxy, except Earth of course.
Battling Vegito and GogetaEdit
After Bulma went back in time to get Vegito and Gogeta, they willingly came to the rescue. They entered a fierce match, but were no match against for him, not even as Super Saiyan 3's. When Vegito proposed that they fuse Gogeta agreed and the used the Potara Earrings so that they would have time to defeat him. After fusing they easily defeated him.
After he was defeated he entered a Space Pod and followed Gogito back to his time, without Gogito even knowing.
- He was capable of Legendary Super Saiyan 3 form, but did not take Gogito seriously, and did not use it.
- After arriving on the earth, he took off right away for a different planet to recover
