Trao

"Sometimes, a strong mind can destroy a strong body. If all you are is strong, then you are weak, for the real form of power is within the mind." "It is not mastering it that makes you good at it, it is your confidence and determination."

Trao was a Yardrat mystic and philosopher who trained Ethan in Other World for a year (1071 - 1072).

Bio
Trao was hatched from an egg on Yardrat, many centuries ago. Growing up, he studied Yardrat philosophy and became very wise, even leaving his homeworld to study philosophy and wisdom across galaxies. On one of the homeworlds he went to, inhabited by an Avian race, he met a wise old hermit who lived in the tallest tree of the planet. The hermit mentored Trao for many years, so Trao spent that time living on the homeworld. One day, aliens invaded the Avian homeworld, and bombed the tree that the hermit lived in..

Trao panicked and rushed to the hermit's help, finding him trapped under many fallen pieces of the tree. The hermit was dying, but before he died, he fused with Trao. The hermits body vanished from existence, but his mind had become part of Trao's mind, and Trao had become much wiser and inherited telepathy, a power that the hermit possessed. He used the telepathy to destroy the aliens that invaded the Avian planet, and save the Avian race. Using his telepathy, he could attack others minds!

Trao spent the rest of his life travelling around the universe, studying. When he was near death, dying of old age, he returned to the Yardrat's homeworld and died in the very same room he hatched in. People had heard tales of his wisdom from across the galaxy, and so, they built him a large tomb to honor him. Goku even saw Trao's tomb at one point, when he was on the Yardrats planet.

After Trao had died, he spent the rest of eternity in Other World, teaching the dead his wisdom. He mentored several Kai's during this time, and he lived in a peaceful hut, located in the wilderness on the Kai's Planet.

Mentoring Ethan
In 1071, Trao met Ethan, who came to him, seeking wisdom. He told Ethan that "wisdom cannot be taught to you, it is something you must teach yourself". Trao taught Ethan philosophy and educated him greatly, he also told Ethan that he must unlock his mind on his own.

Eventually, Trao transferred some of his power into Ethan. This caused Ethan to achieve telepathy and caused him to be wiser, and even stronger! Ethan's power level increased greatly.

Trao had trained Ethan for a year, and Ethan was wished back with the Namekian dragon balls by Zang in 1072.
