Semi-Perfect Cell says "Very well" as he traps the opponent in a Big Bang Crash shot from his hand. Then, he appears above them and fires several Big Bang Crashes down at the trapped opponent. The accumulation of the Big Bang Crashes eventually result in a massive red explosion against the opponent, inflicting a huge amount of damage.
Semi-Perfect Cell uses this attack while searching for Android 18, whom he wants to absorb to achieve his Perfect form. He first destroys an island with a Big Bang Crash to flush Android 18 out of hiding, but when she still does not appear, Semi-Perfect Cell uses the Super Big Bang Crash to destroy a chain of several islands to make it easier to find the Android. When he finally locates Android 18, along with an injured Android 16, he prepares to destroy the island they are on, but Vegeta and Future Trunks arrive and fight Semi-Perfect Cell.
