Fictional character biography
Rex is a White Shepherd dog who spent his early years in the U.S. Army's K-9 Corps, alongside his brother, Pooch. Early in his training it became apparent that Rex had great potential, which resulted in Dr. Anabolus selecting him as a test subject for a super-soldier serum. After receiving an injection of the serum, Rex found himself endowed with great strength, speed, stamina, and intelligence. Dr. Anabolus was killed by a Nazi spy soon after, and as Anabolus left no records, this led to Rex being the only dog of his kind.[6] Rex served during World War II, acting during the Italian campaign and earning an unspecified medal for saving his handler Lieutenant Dennis from a German patrol,[7] and later receiving a Silver Star for saving POWs.[8] He and then Captain, later Major, Dennis followed this by serving in the Pacific campaign against Japan,[9][10] and later in Korea.[11][12]
After his army career, Rex was adopted by Major Dennis and his family.[13] Not long after moving into his new home, Rex began a new career as a crime solver when Dennis's son Phillip was accused of murder and, when the police were unable to solve the crime, Rex succeeded in finding all the requisite clues to clear Phillip's name. Soon after, he was made an honorary Forest Ranger[13] and became a Hollywood stunt dog.[14] In most of his subsequent adventures, he would be seen accompanying Phillip's younger brother Danny.
Over the next few years, as well as solving a never-ending series of burglaries, robberies, murders and other crimes, becoming a film star and a circus actor, and daring natural disasters such as forest fires and thick snow, Rex also managed to survive attacks from lions, wolves, bears, panthers, and even octopuses (twice).[15][16] He could ride a horse, or bull,[17] and proved an expert bullfighter.[18] He often operated small appliances such as cameras,[19][20] swung on ropes and vines to save people. Many of Rex's adventures took place in the American Midwest, but a number happened in Europe, Asia and especially Africa (largely as a result of Major Dennis being involved in various archaeological expeditions). Rex added to his military medals when he was decorated for bravery by the French Foreign Legion in North Africa
Occasionally Rex was forced to perform heroic acts in strange circumstances. Wearing very cool protective shades he once witnessed a nuclear explosion, then fought the Tyrannosaurus rex and pterodactyl that appeared from an underground world as a result of the seismic shift,[22] and fought frozen mammoths on several occasions. In Australia he met an alien, Xstar, and helped him recapture an escaped creature.[23] He soon met Xstar again to solve an outer space crime[24] becoming 'Wonder Dog of Earth' in the process. While staying with a scientist friend of the family, John Rayburn, who created a formula to shrink living beings to microscopic size. They had a number of adventures at a much-reduced size[25] in a sub-atomic world.[26] Pre-empting Ray Palmer, The Atom by over a year, using the formula in reverse, they had several adventures in a giant-sized 'super-atomic world'.[27]
Around this time, Rex was involved in thwarting an attempted invasion of Earth by Martians with the future founding members of the Justice League of America: The Flash, Superman, Wonder Woman, Batman and Green Lantern, among others.[28] After this, he and Danny Dennis became a circus act for many years,[29] where Detective Chimp came to see them and got involved in an adventure with an aging Rex. Taken to the Caribbean, Rex and Detective Chimp accidentally drank from the lost Fountain of Youth and were both rejuvenated. Some years later, Lt. Colonel Daniel Dennis and Rex became part of a U.S. Moon landing team, Rex becoming 'America's first Wonder Dog on The Moon' in the process.[30]
By 1991, it became clear that more than a new lease of life had happened to Rex. While saving the world from Gorilla Grodd, 'the dog at the heart of the world, the dog for whom the universe has waited' (as he now described himself) confidently communicated with the newly sentient animals of Central City, and persuaded them to fight against Grodd.[31] No reason was given for this new ability, but shortly afterwards Rex joined 'The Bureau of Amplified Animals', an organisation of animals with abnormally high intellect run by Detective Chimp to help mankind, and was instrumental in defeating Grodd again,[32][33] also revealing that he can speak, and possesses 'the knowledge of force of mind, and how to use it'.[33] Detective Chimp later explained that both his and Rex's new powers were another effect of drinking from the Fountain of Youth.[34]
Working without Danny
At some point after this, it appears that Danny and Rex parted company, as the now ageing Danny does not feature in Rex's later adventures. After being (accidentally) involved in a fight between almost every DC hero and many villains at the opening of Guy Gardner's bar 'Warriors',[35] Rex later became attached to Hero Cruz (also known as HERO) sometime before he became a member of 'Superboy and The Ravers', and lived with him in Metropolis. Hero, owner of the "H-Dial" from 'Dial H for Hero', later made reference to having discovered Rex imprisoned in a metal box. It is known that Hero found the H-Dial and other heroic relics after breaking into a weapons cache owned by the villainous Scavenger;[36] but it is unknown whether, although likely that, Rex had previously been captured and was found during the same raid. Rex's part in the Ravers adventures was minor, and showed little of his powers. How long he stayed with Hero afterwards is unknown, but Rex was next seen, without Hero, assisting the mystical team Shadowpact in battling the Seven Deadly Enemies of Man, which had been loosed in Gotham City.[37] During this event, Rex was taken over by the entity known as 'Sloth' – a situation rectified by his friend Detective Chimp.
