Thunderbolts, Water Sprites, and Imps

Not all super-beings on Earth are in fact grounded in three-dimensional reality. Some visitors from other dimensions have had influence on the Earths. Such was the case with Mister Mxyzptlk and Mister Mxyztplk from the 5th dimensional realms adjacent  to Earths One and Two, who were persistent pests of their universes' Supermen throughout the years. However, they were only two of the many like powered interdimensional beings invading the Earths' realm, at time indiscriminately using their reality altering abilities.

Bat-Mite's real name and that of his native dimension are unknown. He was more of a hindrance then a help for Batman, although he claimed to be the hero's biggest fan. As such, Bat-Mite would repeatedly concoct various threats that would test the mettle of Batman and Robin, with the Dynamic Duo each time rising to the challenge. Over time, he would also encounter Batwoman, Bat-Girl, Superman  and Supergirl, as well as fellow mighty mite Mister Mxyzptlk whom he had an adversarial relationship with. Eventually, Bat-Mite left Earth-One, migrating to Earth-Prime in an attempt to gain greater fame and recognition.

His counterpart was the Spectre that appeared on Earth-Two. This Spectre would decades later migrate to Earth-One, being replaced on Earth-Two by the Soectre of the Merged Earth (following Crisis on Infinite Earths) during the Asgardian event of 1945. In the 1960s, while threatened by an evil in space, Spectre split off these two personas temporarily. These twin Earth-Two Spectres werw themselves twisted reflections of their Earth-One doppelgängers, Bat-Mite and Alfred Pennyworth’s Outsider alter ego. Both Spectres as well as Bat-Mite and the Outsider had impact on the lives of their worlds’ Batmen. The original Spectre eventually migrated to Earth-One, around the time that the Outsider ceased to exist when Alfred was restored to normalcy. Both Outsider and Spectre would reappear on Earths One and Two respectively on a couple occasions.

As incompetent as Bat-Mite was, he was a savant compared to King Brpxz. This monarch had childlike intellect and was a puppet ruler which his court jester Mister Mxyztplk bossed around. Given his jester's amusing games, the king was content with leaving affairs of state with this troublesome minion. Several years later, Superman and Lois once more encountered Brpxz, who was still not cognizant of his surroundings, much when they met him the first time. 

For a time, Brpxz’s rule was usurped by a much more adversarial king who attempted to wed Mxyztplk to his ugly daughter Princess Bgbznz. This obese king found a corresponding counterpart in Judge Grlprzr, who similarly tried to meddle in the affairs of Mxyzptlk and his betrothed Miss Bgbznz. 

When Miss Bgbznz was exposed, the marriage was annulled, although the Judge officiating the proceedings later confirmed the marital union was still in effect. However, when a vengeful Mxyzptlk (now merged with the consciousness of the Phantom Zone) laid waste to his home world, it is safe to assume that this ended his wedded bonds with her. But that’s a tale left to be told for another time.

Eventually, Brpxz regained his undeserved rulership. However, this King wasn’t a factor in the Earth-Two lives of Superman and his friends, as was his counterpart Miss Gzptlsnz during her handful of appearances over in Earth-One's universe.

Miss Gzptlsnz was the ex-girlfriend of Mister Mxyzptlk, who first met Lois Lane and then became infatuated with the Jimmy Olsen of Earth-One. Due to her unwanted affection, Jimmy was transformed into a wolf-man and later a human porcupine.

When Gzptlsnz returned to her home dimension each time, the effects of these transformations would ware off. She even went so far as to the disrupt the wedding of Olsen and Lucy Lane, which led to a duel between Gzptlsnz and a like powered woman named Rona of the 7th dimension. This conflict caused the bride into backing out of marriage to Jimmy, given the loony alien women in his life.

Thunderbolt went by the name Archibald with his imitate family being his wife Mildred and son Shocko. Indentured into the service of Johnny Thunder, Thunderbolt had to obey Johnny’s commands when prefaced with the keyword "Cei-U" gained through an ancient Badhnesian belt. While the Thinderbolt family of Archibald, Mildred and Shocko aided humanity, their counterparts were arch-foes of mankind. This trio of brothers, Abnegazar, Rath and Ghast, were among the most dangerous of foes for the Justice League of America. On one adventure in the 30th century, these three powerful tyrants battled the League, the Society and the Legion of Super-Heroes nearly to a standstill.. until the three teams turned brother against brother against brother.

While Thunderbolt visited Earth-One on occasion when the evil Johnny Thunder of that world took control of him temporarily and battled the Society and the League, he mainly operated on his master Johnny's Earth-Two (which his own dimension was attached to), and became an unofficial member of the Justice Society throughout both its golden age years and when it was revived in modern times.

There were other Thunderbolts like Mazda, Ampere and Uncle ReVolting existing in Earth-Two's universe... who would their corresponding life forms be? Well, Aquaman of Earth-One met Quisp, Quink, Quirk and other Water Sprites, themselves elemental life forms. These creatures were often benevolent while occasionally malevolent, but did not appear quite as often as had the Mite and T-Bolt. Nevertheless, their abilities matched those of their more famous peers, as they were not only were capable of emitting awesome arrays of energy, but could create matter into various forms limited only by their own imagination! 

Indeed, similar powerful beings originated from the same universe as the Supermen's foes Mister Mxyzptlk and Mister Mxyztplk of Earths One and Two, as has been established as an actual fact in this retrospective.
