4x27 - Dragon Ball Z: Dragon Box

Risking his life to stop Cell as he closes in, and to allow No. 18 to get away, Tenshinhan repeatedly blasts Cell with his Shin-Kikoho technique. No. 16 and No. 18 successfully get away, but Tenshinhan's life is left hanging by a thread. Then, at the moment that Cell is about to wipe out Tenshinhan, Goku instantaneously moves from Kami's temple to stand before Cell!
