Beta Capsule

Beta capsule (ベータ カプセル Beta Kapusuuru) is the first tranformation item to be used in the Ultra series.

Ultraman
The deputy captin of the Science Patrol, Shin Hayata was patroling around the tokyo, when he noticed a U.F.O flying over a lake, a large blue sphere, the travel sphere used by the then unseen monster Bemular. When flying closer to infestigate another U.F.O crashed Hayata's plane. The being inside the red sphere was the hero known as Ultraman.

Ultraman telepathiclly informs Hayata that he was pursuing the monster Bemular, and had accidentlly crashed into Hayata's ship when he was trying to follow Bemular. He then gives the Beta Capsule to Hayata, merging with him to provide the dying human his own life force. After that, using the power of Beta Capsule, Hayata could become Ultraman.

Later on, after Ulraman's defeat at the hands of Zetton Zoffy appears to retrieve Ultraman, knowing he could not take the Human back with them to the Land of Light, Zoffy pulled out his own Beta Capsule and seperated the two back into seperate beings, but with Shin having no memory after his plane crash.

Ultraman: The Ultimate Hero
Ultraman Powered gave Kenichi Kai a device, which in the English version was called a Beta Capsule, instead of holding it upright it was held in a clenched fist and had two LEDs, one on each side. It was perhaps a newer version of the same device.

How to use
Hayata raises the Beta capsule to the sky and press the red button starting his transformation into Ultraman.

Trivia

 * The fact that Zoffy himself carried a Beta Capsule, implied that was a widely used object, in fact Ultraman powered's transformation device, although it looked different was called a Beta Capsule in the English Version.
 * The Beta capsule can easily be mistaken for a children's toy, or even a spoon.
