The Mysterious Foe

"Boy, have you not realized yet? I am unstoppable."

The Mysterious Foe is the main antagonist of Dragon Ball: Gods who are Gone. He suddenly appeared in Satan City one day, wreaking havoc and destroying everything around him. When he stepped on the ground, craters were caused. He was so powerful that even when he drew what he considered to be "the tiniest bit of energy possible," it caused the clouds to conform around him and the Earth below him to shake uncontrollably; the Z Warriors arrived to stop the foe, but the battle took many of the fighters' lives.

During the foe's battle between the Z Warriors, a human named Rasse tried to kill the foe in revenge for murdering his loved ones; but to no avail, and the foe proudly stated "I am unstoppable."

He was so powerful that Goku himself sacrificed his life in a kamikaze-bomb like attack to seemingly destroy the foe, his last words being "I'm...sorry...my--". The explosion from the kamikaze attack destroyed Satan City, but Rasse survived.

Eventually, the foe resurfaced in the city Balle-Dagga, and Rasse, determined to disprove his enemy and defeat him once and for all, drove off to fight him once again.

He is known for looking extremely similar to Goku; it is later revealed that the two are related.

Personality
The foe used to be a kind individual, but he slowly devolved into madness from the pressures of containing so much power inside of him. Eventually, he could not take it any longer, and he unleashed the powers he had held back for so long and let himself fall victim to its corruption.

Now, he is cold, heartless, jaded, and prideful. He cares little for anyone around him and is always seeking a challenge.

Powers
His power level is staggeringly high, coming in at nigh-centillion levels. It is so powerful that when he would step on the Earth at his weakest state, it would cause 1,000 foot wide craters, and the shockwave would be felt even in the far reaches of space. The air flickers every time he moves, and when he powers up, the damages to the environment are catastrophic.
