Asteroid

Asteroid was the Winner of Big Brother 6, and a houseguest in Big Brother 7 - All-Stars.

BB6
Weeks 1, 2 and 3. Asteroid really didn't do much. He didn't win a competition, and was never put up for nomination. Week 4 though, was eventful. He won the HoH, and put Box and Fat Alien up. He then double downed by winning the PoV and discarding it. Then in a 5 to 5 tie, he was the sole vote to evict Fat Alien. Through weeks 5-8, Asteroid sat back and watched the others, as he never won a competition, and due to his social game, and acting nice, he was never put up for nomination. Week 10, he won another PoV, and decided not to use it, watching Star get evicted. Week 11, nothing happened, and Week 12, he was nominated for the first time, he won the PoV though, and saved himself. He proceeded to win Week 13's HoH, and the Final HoH, taking Party Hat to the finale with him, and winning in the only perfect juror vote, 7 to 0.

Asteroid is currently the only Houseguest to have a Perfect Game.

BB7
Asteroid was the first person accepted for All-Stars, as he played a Perfect Game.

Asteroid's BB7 Game surprisingly didn't last long. He wasn't immediately targeted as his social game was great. He didn't win the HoH or PoV for Weeks 1-4. He was nominated Week 5, because Pen realized his game. He didn't win the PoV, but was safe in a 8 to 5 vote against Test Tube. Asteroid didn't think too much of this, and kept using only his Social Game. He was safe Weeks 6 and 7, not winning a HoH or PoV again. Week 8, he was nominated by Baseball, didn't win the PoV. And this time, was evicted in a 7 to 3 vote against Golfball.
