Garlic Jr. Saga
Return of Garlic Jr. from the Dead Zone
Gohan: 45,000
Master Roshi: above 200
Krillin: 43,000
Tein: 49,250
Yamcha: 40,500
Chal-zu: 21,000
Piccolo (still merged with Nail): 800,000

Keep in mind that Tein, Yamcha, Chal-zu were traning very hard at King Kai's house. Plus when King Kai invited the Ginyu force Tein, Yamcha, and Chal-zu defeated them in combat with no problems. Also keep in mind that Piccolo is fused with Nail and has a realy high powerlevel. On the other hand Krillin and Gohan have been in combat all through out Freeza Saga. So, that eventually raised their powerlevels higher.

Welcome the 4 Spice boys
Vinegar: 89,500
Mustard: 87,000
Spice: 63,000
Salt: 51,000
Garlic Jr. (not transformed): 600,000

Remember Tein, Yamcha, Chal-zu, Bulma, Chi-Chi and Master Roshi all fall prey to the Black Water mist. Keep in mind Kami in part of Picoolo. But Garlic Jr. has traped Kami in a small glass bottle. Now with Kami traped, Piccolo can't fight in his maximun power. This drops Piccolo's powerlevel drastically.
