Omega Shen Long used this attack in Dragon Ball GT to prevent Goku from getting his vision back. After that, he instantly fired a second energy beam to kill Goku, but Nuova Shen Long got in the way to save him and was killed. He also used it multiple times against Goku, as well as using a continuous version of the attack. Omega also used a red finger beam variation similar to Kid Boo's Energy Finger Beam against both Goku and Vegeta in their Super Saiyan 4 forms.
The Energy Finger Beam was a signature move used by the Artificial Human duo of Future Artificial Human No. 17 and Future Artificial Human No. 18 in Dragon Ball Z: The History of Trunks.
