The Beta Spark is Kyotaro Misaki's transformation device, which allows him to transform into the giant hero Giz.
The Beta Spark resembles the Beta Capsule, but has a blue crystal on top surrounded by black lines. It also has a lightning bolt emblazoned on the side.
Kyotaro can also pull the crystal foreward, causing it to automatically unfold into a gun with the crystal as the tip. This can fire a powerful bolt of electricity, or be used as a flare gun.
Kyotaro puts the Beta Spark out to his side, absorbing lightning energy, before raising it above his head shouting:
He is surrounded by white light, then Giz rises from a background of crackling lightning bolts.
- Flare Gun: In Gun Form, the Beta Spark can fire a bolt of fire as a flare.
