Just like the name implies, it is like the Big Bang. In episode 121, this technique was mentioned first, as an unknown comibnation technique by Hiroto, Fubuki and Kidou in training. In episode 124, the technique was completed and used first, being strong enough to get through Kane Saitoo's 真 God Hand X, injuring his wrist in the process. After Rococo switched back to goalkeeper, the three used Big Bang again. However, Rococo's desire to win let him create a new goalkeeper technique, Tamashii The Hand, that stopped the powerful shot.
The first user runs with the ball while the second and third users jump. Then, the first user makes a volley and two purple rings form around the ball. The second user kicks it upwards and the third user strikes it downwards with their heel. An explosion occurs around the ball, surrounded by a ball of orange energy with blue edges in space. Finally, all three users kick the ball at the same time and the ball moves toward the goal surrounded by a huge ball of fire.
