Kochin's Shenron-inspired cane handle
Dr. Kochin's Cane is a jade-colored walking stick belonging to the android scientist Dr. Kochin.
Overview
The cane firing
The handle is carved to resemble the head of the eternal dragon of Earth, Shenron. Kochin was normally seen hunched forwards slightly, apparently using the cane for support; in truth Kochin's cane is a weapon. The top of Shenron's head tilts forwards, revealing a button. When this button is pressed, a gigantic blast of energy shoots out of the cane.
Kochin used the cane during his attempt to kill Gohan, after taunting the boy into raging anger. However, Gohan repelled the cane's energy and Kochin dropped it in surprise. When he moved to grab it afterward, Krillin kicked it aside. Nevertheless, Kochin re-obtained the cane shortly thereafter, following the loss of one of his arms, and he was still holding it when Dr. Wheelo accidentally knocked him off the laboratory platform. He dropped it during his fall down the shaft.
