Instant Spirit Bomb (瞬間移動元気玉) is a combination of the Instant Transmission and Spirit Bomb used by Goku in his Super Saiyan form. After Goku has gathered enough energy, Goku throws the Spirit Bomb towards the opponent. Then, he uses Instant Transmission to appear in front of the opponent and punch them in the face before teleporting away. The powerful punch delivered by Goku distracts the opponent long enough for the slow moving Spirit Bomb to successfully hit them.
Goku used this attack to defeat Hatchiyack in one of the alternate endings of Plan to Eradicate the Saiyans. Steve also used this technique in his super saiyan state on Super 17 during the end of there battle incinerating the android into a crisp.
