This arc see the return of android 16 after mysteriously dissappering after the Cell Saga. The Garlic Jr. ...
This saga begins with the traditional Martial Arts tournament where we find Goku (still a child) competing in the children divison of the tournament due to a height requirement (though truthfully Mr. Satan made up the rule cause he was scared to face him) while Pan fights in the adult division. Pan manages to make it halfway through the tournament but the thought of looking like Hercule if she won scares her and she drops out. Goku also easily makes his way through the tournament, but a distraction by Vegeta causes him to accidentally get knocked out of the ring by his opponent. In the end it Hercule vs. Pipiea Man (Uub in disguise), where Hercule wins when Majin Buu contacts Uub within him (he was absorbed in the Baby Saga by Uub) and explains why Hercule needed to win: to keep the hope of the people since he their hero.
Afterwards, we go to the underworld (or HFIL) where Dr. Myu is wandering around and is met by Dr. Gero (from teh Cell Saga). Seeing that the two have Goku as a sworn enemy, they team up to get revenge. Building a artifical Android 17 then contacting the real one on Earth. Afterwhich the two androids open a rift to Earth allowing all the villans from the past two series to escape and cause chaos. King Yama contacts Goku of whats happening and Goku flies through the open portal to find out whats going on.
Once there he immedently meets up with the two scientists and their andorid but they take off through the portal and goes it trapping Goku in the otherworld. If that wasn't bad enough, two of Goku's worst enemies from the past, Freiza and Cell, have stay behind to exact their revenge.
Back on Earth, Goten, Trunks, Uub, Vegeta and Pan are easily dealing with their past adversaries. Durings this ruckus however Krillen and his family and stuck in traffic watching what happening least until the real Android 17 confronts them and tries to get his sister, 18, to rejoin him. After she refuses, 17 kills Krillin and then tries to kill 18 after she tell her daughter Marron to escapes. As 17 flies away, 18 crawls to her husband before she stop moving.
