Kikouhou

Tienshinhan first uses this attack during the 22nd World Martial Arts Tournament against Goku, and used it at Kami's Lookout against Yamcha. This technique is performed by gathering energy, forming a triangle with the hand by keeping the fingers on each hand together, overlapping the index finger on the one hand with the pinky of the other hand, and overlaping the thumbs. The object being focused on gets zoomed in on and visualized inside that triangle, then the user (namely Tien) shouts "Tri-Beam, ha!" while releasing the large yellow beam from the hands. Tien also has the ability to fire it with one hand as seen when he fires the Spirit Tri-Beam at Nappa after he loses his arm.
In addition to being able to kill the target, the Tri-Beam can easily kill the user, as it drains their life energy. The attack has a tendency to cast the entire environment around it in a deep orange glow. Interestingly, this technique leaves a square hole in the ground, instead of a triangle. The attack formation itself places the hands in a seemingly awkward position; and it appears that later in the series, the finger tips are touching, and the thumbs are the only things that overlap.
After training with Korin, Kami, and later King Kai, Tien perfects the attack as the "Neo Tri-Beam," which is essentially an "upgraded" form of the attack that allows him to control and enhance how much energy he puts behind it, inflicting even greater damage. This upgraded attack is powerful enough to hold even Semi-Perfect Cell at bay. The attack is extremely powerful, and despite the massive gap between Cell and Tien's powers, Cell was unable to break through the repeated blasts, though they did not inflict any real damage to him. Tien eventually collapsed from using the technique too much, but was saved from Cell by Goku.
While Cell himself has not been seen using it (although he possesses data about Tien's techniques), during the Cell Games Saga, the Cell Juniors attacked Super Saiyan 2 Gohan with it, although to no avail.
It was once told by Master Roshi that it is such a strong technique that it was even stronger than his kamehameha wave which easily destroyed the moon.
