Last Time: Gotenks and Super Buu's battle reaches new levels of intensity as they begin to cause massive damage to the environment around them. However, Gotenks ends up using too much energy, and his Super Saiyan 3 form collapses.
This Time: Without his Saiyan 3 form, Gotenks now stands no chance against Buu. Fortunately, Gohan has finally reached new levels of power!
NOTES: Tonight's episode airs after a new Super. Watch them both, and no spoilers!
