This is Son Gohan from Dragon Ball Z, changed into Super Saiyan 2 form!
It's part of Figure-Rise Standard line by Bandai and requires assembly, but there's no need for glue and the parts are already colored.
The resulting figure is highly detailed and articulated.
It comes with 2x faces, 4x hands and parts for the Kamehameha!
Action Bases 1 and 2 shown in the images are sold separately
