Dragon Ball Z: Dragon Box

Season 1 | Episode 35 - Cause a Miracle! Son Gohan, the Super Saiyan

Feb 7, 1990

Barely alive after taking the force of Vegeta's shockwave, Gohan regrows his tail! Gohan transforms into a Great Ape as Yajirobe and Vegeta fight each other. Having lost all reason, the Great Ape rampages, but perhaps as a result of Goku and the others' desperate call, he at length starts attacking Vegeta! Vegeta manages to cut off the Great Ape's tail, but is unable to avoid the falling Gohan, and with his energy spent, he is crushed beneath him.
