Tragically, Wesley's first attempt to activate his revolutionary silicon gun left his adopted ward and sidekick Sandy Hawkins transformed into a Silicoid monster possessing a sinister disposition. Kept in a slumbered state for decades until a cure was found to reverse his state, Sandy developed mastery over his shape-changing abilities. Meanwhile, Dodds used a refined form of his silicoid gun in his crime fighting in the mid 1960s, and later used it during a time travel adventure during the reign of Genghis Khan in the Gobi Desert.
While initially coming into conflict with his world's Flash, and the rest of the Justice Society of whom Sandman was a charter member, Sandy revealed his heroic nature. During his years-long semi comatose state, Hawkins was able to expunge his barbaric personality, manifested when he was initially transformed.
But there were other means, developed by scientists, to unlock metahuman potential in themselves and others. Among these were miracle medicines or divergent drugs, such as those considered below. These examples are both a small sampling of the many possible chemical combinations potentially available in each universe.
Zoologist Kirk Langstron of Earth-One sought to harness traits found in the unique flying mammals which inspired his personal hero, the Batman, Through his Bat-Gland serum, Langstrom was able to transform his body into Man-Bat, a hybrid hero blending but human and bat into a new life form. Initially, his transformations affected his mind, until Batman was able to help him regain his sanity. Man-Bat would oscillate between hero and villain, using his wings to glide, his sonar sense to navigate and his superior strength to subdue his foes.
Chemist Rex Tyler of Earth-Two developed the Miraclo pill, enabling him to obtain superhuman strength, speed, durability and agility for one hour at a time. As the Hourman, he successfully carved out a costumed career for himself, soon after becoming a founding member of both the Justice Society of America and the Freedom Fighters. However, addiction to Miraclo caused Rex to experience adverse affects, leading him to partially retire until he could reformulate his miracle drug into a safer compound.
Research assistance Duncan Pramble of Earth-Two worked alongside an archaeologist when he discovered an ancient elixir known as Liquid Light, which when ingested caused Pramble to mutate into various bodies. Each body had its own superhuman abilities, which he used unsuccessfully as the supervillain Multi-Man, as the Challengers of the Unknown defeated him time and again, as its leader and resident scientist Prof Riley developed an anecdote that neutralized Liquid Light's effects.
Rex Tyler eventually developed a variation on his Miraclo treatment, creating a Black-Ray device which helped him unlock the pills powers by bathing in its radiation. Eventually, Tyler developed a safer version of Miraclo, perhaps derived from investigating the foe of his Justice Society ally Doctor Fate. That foe, Mister Who, had himself developed the Z-Solution which allowed him to transform into various forms similar to that displayed by both Multi-Man and Garfield "Changeling" Logan of Earth-One, who's father treated him with to save his life. Having observed how Mister Who displayed no detrimental physical defects to his solution when both Doctor Fate and Hourman battled him, Tyler may have adopted part of Who's formula and integrated into his reinvented Miraclo pill.
In the DC Multiverse, hard water has different physical properties in each universe it exists within. Two instances of this are in the parallel planes of existence known as Earths One and Two. And the individuals who manifested divergent abilities from this particular property as Mera and the golden age Flash.
On Earth-One, the queen of adjacent Dimension Aqua known as Queen Mera possessed the power to solidify water particulars into various objects. While other inhabitants of her native realm likewise possessed this skill, including her twin sister Hela, it was Mera who mastered it.
Jay's Garrick Research Laboratories experimented with hard water years later. The lab's scientists concealed this substance, which inadvertently unleashed their hyper-accelerated stored kinetic energy, which proved fast enough to even challenge Garrick as the Flash. Whether Mera's Earth-Two counterpart Queen Eeras ever employed hard water weaponry in Atlantis is also unknown.
Interestingly, the Water Sprites of Earth-One had hard water based powers similar to Mera, who were allies of she and her husband Aquaman. Qwsp and his Sprite brethren’s doppelgängers on Earth-Two were the Thunderbolts with lighnting-based powers derived from sparks of electricity similar to that which empowering a Barry-Flash. They were of the Thunderbolt Dimension, the Earth-Two version of Earth-One’s Dimension Aqua.*
* While on Earth-One, lightning energy translates into speed force and hard water translates into solidified constructs, on Earth-Two it is the reverse with hard water translating into speed force and lightning energy into solidified constructs.
