He trained to become powerful. He went across the Aourgeiy Universe, fighting evil in a somewhat unforgiving manner, for many, many years, until finally, the painful memory of his lost love made him realize that in cruelty he had partially become like his enemies. He changed his ways and became a true role model across his universe.
After some time, he came across what is now one of his favorite planets- Earth. At the time, there were few intelligent inhabitants, but there were enough people in Egypt to have a society. Upon landing in the deserts, the Egyptians saw him, noticing that he had come from the sky and that his appearance was like that of some cat but also human, and decided that he was a god. Tygerans always find a "second home" planet sometime in their campain to become familiar to the universe, and when they find it, they hide part of their power within a secret temple. Tyger decided this was as nice a place as any for that, so he gave his prized pyramid, a gift from his late fiancé and the symbol of fertility on his planet, with a power-imbued scarab within it (the insect, symbol of secrecy), to the Egyptians. His instructions to them were to build the largest possible copy of the pyramid as possible, and hide the scarab within the top. They could do whatever they wished with the rest of it. He then took his wedding gift and left the planet.
A thousand years later, after finishing his training on the ultimate planet, Tyger decided to go back to Earth and see how things were going. Ultimately, he placed two more Tygerans' temple powers on Earth, making it the most Tygeran-known planet in the galaxy, at least.
Finally, at the age of four thousand years, he returned to Earth again to find it a giant city. The people had become technologically advanced, and built skyscrapers across the planet. Humanity seemed on the verge of ultimate discovery. Tygehr'ra found amongst the population of six billion one woman, An, who made him decide that he was done crossing the universe and fighting evil, and he decided that he would take a human form and live on Earth with An forever. But a certain life form far away wasn't happy about that. Auuoghorghoouh, the Tendronn-multy who had killed Tygehr'ra's first love, came to Earth and began terrorizing its citizens. Tygehr'ra was forced to confront a much stronger enemy, and was almost killed by the Tendronn-multy, who could heal himself instantly, until An saved his life. Unfortunately, she subsequently lost her own. When this happened, Tygehr'ra became royally pissed, and summoned another evil-destroying shock to kill Auuoghorghoouh for good.
Later, however, Tygehr'ra met his match in Kalvos, a demon from the stars come to destroy Earth and enslave the universe. Tygehr'ra alone could have beaten him, but Kalvos was too sly to be destroyed, and calling up his demon friends (Lucifer, Beelzebub, and Mephistopheles), ambushed Tygehr'ra and killed him. By drawing on the power within his temple, Tyger had the ability be reborn within a person on Earth and share bodies with that person until he gained strength to transform into Tygehhra'Nach'T, which was just what he did. Tygehhra'Nach'T Naharazeth du Tygeran merged his soul with that of Machi Tyger Landrunner and became once again a universal protectate.
