Ultra-Humanites and Brainy Bedevilers

The original supervillain, at least in DC Comics, was Ultra-Humanite. Before Lex Luthor stole the limelight forevermore, it was Ultra that first showed the world that bald can be beautiful. Or bedeviling. And be that as it may, since Ultra has assumed many forms we're going to recap some of the more prominent ones, and their Earth-One doppelgängers.

On Earth-One, an android named Brainiac was created based on the brain patterns of a scientist from the planet Colu-One. Having shrunken and collected several cities across the galaxy including Kandor, this brought Brainiac to the attention of Superman who freed those cities and began opposing the android's schemes. On Earth-Two, a bald scientist formerly a vagrant named Bill Dunn, who has been subjected to experimentation enabling him to gain grand intellect as well as an aptitude to assume various bodies throughout the decades. 

This genius known only as the Ultra-Humanite used various technologies to plunder and try amassing power, for which he had several battles versus Superman. A variation of Ultra's psyche was replicated as a synthetic being on the planet of Colu-Two as an assistant of Vandal Savage, who created that world to trap Superman. In his next form, Ultra would gain the ability to absorb energy and wield tremendous energy. 

When old man Ultra lost his body thanks to his own deadly backfiring purple plague ray, he was forced to have his brain transplanted into the body of kidnapped victim Delores Winters, an actress. She attempted to seduce atomic scientist Terry Curtis to build for her a deadly weapon on Earth-Two. On Earth-One, Paula Porter was a research assistant who was accidently exposed to experimental orchids with thorns. When stabbed by these, she gained powers and decided to embark on a costumed career as the Black Orchid.

Like Orchid, Ultra gained superhuman strength and the ability to project energy although she derived said powers from a Powerstone. While Black Orchid was a heroine who disguised herself in multiple identities to infiltrate criminal enterprises and gang in order to defeat them, Ultra Humanite used her famed alter ego to seduce allies to join her in her criminal schemes. While Orchid teamed up with Superman and the Super Friends on one case, and with several mystery heroes on another... Ultra was a foe of Superman alongside his All-Star Squadron allies 

The next transplanted body for Ultra was in a flying ant, mutated thanks to the power of Lana Lang aka Insect Queen. Her counterpart had a part to play as well, coaching a boy named Kim mutated to save his life into Bee-Boy! Thankfully, this lad had a brief criminal career before being healed.

Finally, we meet the sinister simians stringing-along the Secret Society of Super-Villains! Gorilla Grodd was a deviant of Gorilla City, wanting to do harm rather than good to his fellow kind. Banished from his land, he became a perpetual thorn in the side of the Flash. 

Eventually, he branched out and made enemies among all the Justice Leaguers, causing him to join and soon lead the Secret Society for a period of time. Ultra-Humanite himself soon learned that the scores of bodies he claimed for his malicious mind were burning out to quickly, so he mutated an ape to house his brain. Immediately, he too recruited villains for his own Secret Society. While Ultra remained in this form from then one, Grodd sought escape from entrapment by transplanting his brains in bodies such human as Drew Drowden and William Dawson, but ultimately reverted back to his natural form. 

The names of Ultra's other bodies have never been revealed, although one of Grodd's once known as William Dawson had a doppelgänger in Johnny Bonman, who lie Dawson had briefly possessed mental powers before returning to normal thanks to the intention of a Flash in each case.
