Radian (Louis Armanetti) was created by writer Peter B. Gillis and artist Brent Anderson and debuted in Strikeforce: Morituri #1 (December 1986).

A jokester and quick to mask his insecurities and fears behind jokes, in 2073, Armanetti volunteered for the Morituri process, a revolutionary scientific progress which gifts ordinary people with superhuman abilities.

[1] After all members of the Morituri had successfully underwent the process, they were dispatched to the Biowar Zone Alpha (nicknamed "the Garden"), a specially designed facility filled with several dangerous traps.

The shock of the experience unlocked his ability to emit electromagnetic radiation blasts and he managed to set himself free by burning the gas toxins in his body.

Subsequently, he took on the nom de guerre "Radian" and designed a costume with special sleeves, which helped him focus his blasts more effectively.

After Vyking's death in a spaceship en route to the Horde fleet, Radian was the only one to oppose the idea of continuing with their mission, although he complied when the team decided to keep on.

[5][6] Following Vyking's demise, Radian, who was used to taking orders in battle, began looking for another leader figure and tried to pressure his new teammate, Toxyn, into this position, much against her chagrin.

Through the cassette, the Kind Inquirer of the Horde made Radian a tempting offer: he professed possessing a cure for the deadly Morituri effect.

In the video, though, Higashi appeared to be still alive, albeit a captive of the Horde, approximately sixteen months after he had been subjected to the Morituri process, meaning he had long outlived the time limit of the deadly effect.

That same day, teammate Scaredycat presented him with a communication she had intercepted, which proved that the team's employers, the Paedia Council, were discouraging Dr. Kimmo Tuolema, inventor of the process, from searching for a cure for the Morituri effect.

It was only after Radian claimed that he had done all this in order for them to commandeer a Horde ship and for their teammate, Adept, to come in contact again with invaluable artifact stashed in their space fleet and catalogue them in her memories through her analytic abilities, that they were convinced of his good intentions.

Higashi tried to discourage Radian, arguing that what he was suffering now was worse than death, but the Kind Inquirer did not allow him to continue his communication with the Morituri.

Indeed, Radian was forced to transmit a message throughout the globe, in which he informed the public that there is, in fact, a cure for the Morituri effect, but the Paedia refrains from discovering it, wanting to keep their superpowered warriors under check.

[13] Radian had the ability to emit E-M radiation across the whole spectrum, from radio lines to low level gamma rays, to various effects.

Besides the aggressive use of his power, he was seen utilizing his radiation control in different ways, such as burning the nerve toxins in his body, emitting blasts with carrier waves or producing a viable phone signal.
