Dragon Ball Z - Episode 245: "Super Saiyan 3?!"
Toei Animation looked at that version and said no.
What we got instead is three minutes and thirty-five seconds of Goku screaming while the planet files a noise complaint. Animation supervisor Ichio Hayashi and the episode's key team didn't just produce a transformation sequence. They produced a weather event. The line-weights go dense and frantic. Heavy black shadow floods the close-ups. The animators drew individual pulsing veins on Goku's forehead and micro-reflections inside his contracting irises to sell the physical strain of what he's doing to his own body. The background plates of the rocky wasteland don't just shift. They violently jerk behind him while hand-painted lightning bolts snap across the frame on two-frame intervals. The entire sequence is animated like the earth itself is trying to get away from what's happening.
