Great Saiyaman is traditional cache that is part of the Dragon Ball series.  You can complete this cache as either an individual cache or part of the series. If you decided to go on and complete the rest of the series (highly recommended), you should take pictures or notes of the inside lid of every Dragon Ball cache you find.  Some of them require collecting certain caches first so please plan ahead and I guarantee you will enjoy your caching experience even more.

Great Saiyaman 

 is the alter-ego of Son Gohan.  He uses this name and costume to hide his true identity from his classmates.   The whole effect is just comical.

This cache is located at the bottom side of the Fukuchi Dam.  It should be a lot of fun as getting to the GZ cannot be done directly.  Once you get there you will see.  

DO NOT, attempt this cache if the Dam spill off canal is gushing out of control.  Otherwised make good use of the stepping stones in the water.  Once you find Great Saiyaman, you can get a puzzle piece to find a Dragon Ball.

Good Luck.
