I'd like to talk about Helios' Rogue's Gallery (not every single one but most)

To be honest, unsure what flair to put it under but it's nor just a group and such, as they're mostly individuals each appearing in her long story. I LOVE the ideas of Heroes having "Rogue's Gallery", sometimes they don't but most of my heroes do. I'd appreciate any questions on any of them!! I'd love to yap and talk about each one more in depth if you wish!

Arjun Singh

He's a CEO, he started out as an ally but behind the scenes he was working on taking Helios' power for himself as he "trained" her and "helped" her becoming a mentor for her after he fathers death, which he killed him and blamed it on the "Mindbender" an attacking villain and later everything came to light, making him a villain.

The Mindbender

Now, she has the abilities to take over minds, she was made by Arjun Singh, to fight in a war 20 years before Helios even existed, she was a clone of a captive hero with the same abilities many clones were made, both male and female versions, all the other clones died due to her, she betrayed the side she was made for, joining the invading aliens, the Dezu and later returned about 20 years later as the Dezu commander told her to get the symbiotic alien attached to a hero, which would be Helios.

Lilith

We're entering a theme here, Lilith here worked for Arjun Singh and she was tasked with researching black holes and how to stabilize them to make them into military weapons and she managed it, she made a black hole, stabilized it... Then Mindbender, her real name is Sophia pushed her into it, it didn't kill Lilith but it made her into something else, details would make this longer so.... We'll skip 'em, she came back but she felt empty, hungry, no matter how much she absorbed she was never full, she became a living black hole.

Claire Navarro

Claire, once a scientist specializing in light and quantum physics. During an experiment to harness quantum light energy, an explosion merged her with the light spectrum, giving her the ability to control and become light itself. She couldn't control herself, so she tried finding a way to reverse it but she was named a villain, being in that form so long warped her, her mind became something else and she embraced it, facing Helios countless times.

Dreadnought

Isaac Steele was a soldier who was grievously injured in battle and left for dead. He was found by a rogue military scientist who rebuilt him using experimental cybernetic technology, turning him into a living weapon. Now, as Dreadnought, he works as a mercenary, selling his services to the highest bidder. By design, not an evil villain, he just gets hired to go after Helios by some people for whatever reason.

Cyrus Ambrose (Codename: “Ragnarok”)

Cyrus Ambrose is a legendary bounty hunter, known for his unmatched physical prowess and intellect. Born with peak human abilities, Cyrus spent his life honing his skills, pushing himself to the limits of human potential. His reputation grew as he took on increasingly dangerous contracts, often involving powerful aliens and superhumans. After a life-threatening injury, Cyrus had his bones replaced with a nearly indestructible metal, further enhancing his strength and durability. His most unique ability, however, is his power of teleportation, which makes him an almost unstoppable force in combat. Same as Dreadnought really, just stronger.

Commander Reonu

This is a commander of the Dezu army, the alien species and came in contact with Helios several times and putting her on the brink of death, he was a minor villain at first then became more prominent after Helios and Dark Wizard destroyed the Dezu planet, the Dark Wizard did the destroying, she asked him to, to stop the infectious Dezu species, they'd never stop otherwise and Dark Wizard had a spell for such tasks, Reonu is avenging his species so she made it worse.

Morgan, Stephen, Rufus and Bradley

These 4 come as a group called, "Eternity", they use musical instruments cursed by demons, they are demonic instruments, which gives them abilities and each instrument does something different individual but when played together anyone who hears their music is compelled to dance uncontrollably. Their eyes glow with a haunting light, and they move as if possessed, unable to stop. The longer they dance, the more pain they feel, until they are driven to the brink of madness or death. And being involved with the "Blood Cult" and Arjun Singh, they naturally fight Helios on several occasions.

Halo

He's the opposite of Helios, she takes power from the sun, he takes it from the moon, the reason they're enemies is nature, Halo too has a symbiotic alien attached to him which hates Helios' so Helios is still allowed to do whatever with the symbiote, it doesn't control her, Halo's does control him.

The Blood Cult

Uhm.... Yeah, this'll be too much to explain every member but I'll name the key members

Blood God, Father Blood, Puppeteer, Speed Demon, Psynapse, the living mask of emotions and Hazel. Key members, it's an army of cultists and main culprits of the "Blood Moon" War, simple as that and often fighting Helios until they were all finally beaten at the end of the war.

Yeah, that's the main ones
