Double Tsuibikidan is an energy wave attack used by Krillin. Krillin bends down as he brings his arms to his sides and charges up. Then, he brings his hands forward and fires two reddish-orange energy waves that follow the opponent like homing missiles, inflicting a great deal of damage.
Krillin uses this attack during his match against Piccolo in the 23rd World Martial Arts Tournament. Piccolo thought nothing of this attack and merely jumped into the air, but he did not realize they followed him and was almost hit from behind. Though Piccolo managed to destroy the Double Tsuibikidan with his eye lasers, this was merely a distraction as Krillin appeared behind Piccolo and punched him in the face.
Later, when he and Future Trunks destroy Dr. Gero's basement laboratory during the Androids Saga, Krillin uses the two handed blue beam. He and Trunks blast various objects in the laboratory, including Present Cell in his larval form.
In Dragon Ball Super, Krillin uses this attack against Goku during their fight in "Goku the Recruiter Invites Krillin and No.18"
