The Stellar-Energy Helmet operates on radio-emissions from the stars. It inspires the one waenring it with sudden bursts of brilliant ideas (which Axel Storm called brain storms).
It also boosts the wearers natural brain power, enabling them to fire lightning-like blasts which permit control over anything they strike.
The blasts also allow grant the wearer the ability to animate lifeless objects and teleport himself or others.
However, a side effect is that whoever the power was used upon could also access the energy abilities. Meaning that those whom it used against are mentally linked to the wearer.
