Antenna Beam (怪光線, lit. "Monster Light Ray") is a bolt of electricity fired from the antennae. The attack shocks its victims, stunning them.
This is first used in the Dragon Ball anime when Goku invades Muscle Tower, one of the main bases of the Red Ribbon Army, and faces off against Buyon. The monster uses this attack to daze Goku, allowing Buyon the chance to try and swallow him, though Goku quickly escapes from the creature's mouth.
The Gatchans uses Antenna Beams against General Tao in the movie Dragon Ball: Mystical Adventure. They also use this technique in the Dr. Slump series, using it for the first time in the chapter "Kids Gone Wild", and later against Ogre-king Gyaska, Dodongadon, and again against the vacuum worker in "Vacuum 1982".
It is next seen during the 23rd World Martial Arts Tournament in which it is used by Piccolo. After Goku hits Piccolo with a double punch driven by a Feet Kamehameha, Piccolo quickly retaliates with the electric blast. Goku is sent crashing to the ground and left vulnerable to a follow-up attack, though it is intervened and blocked by Kami.
This attack then makes a grand reappearance in the Universe 6 vs. Universe 7 Tournament held by Beerus and Champa. Piccolo uses this technique while charging his Special Beam Cannon against Frost in order to stall him long enough. Goku states that he hasn't seen this technique in a while.
Majin Buu also has his own version of this attack, performed like the Chocolate Beam in the Budokai Tenkaichi video game series. This attack is also inherited by Evil Buu, Super Buu, and Majuub. In Nekomajin, the demon Jajan uses the attack against Neko Majin. King Piccolo also uses the Antenna Beam in the Budokai Tenkaichi series. The Antenna Beam can also be used by the Dragon Clan Namekians in Dragon Ball Online.
