WN/Rudra Nam Ul Nasca

Rudra Nam UI Nasca is a former emperor of the Eastern Empire

Appearance
During his time with Guy Crimson, he is considered as Biseinen (Beautiful Adult Man).

Personality
In the past, he was a heroic and kind man who held ideas to construct a world free of poverty and war. He took issue with Guy's sworn duty of counterbalancing humans, crushing them whenever they get full of themselves and challenged him repeatedly to try and get him over to his line of thinking. This would in time lead to a war game where Guy leads the Demon Lords and Rudra leads the humans. He was brother in law to Veldanava, first among True Dragons, and has carried the Justice King Michael Ultimate Skillon his request for the past two millennia. The burden of suppressing this skill has weighed on him so much that it has all but destroyed him. Recognizing that Michael's absolute justice is hardly itself different from evil, he requested Damrada to find someone capable of killing him during his last lifetime. Velgrynd also seeks to kill him after he falls completely to the skill's influence, namely out of devotion to him. As Emperor he shows himself to be a cold-hearted and ruthless absolute monarch who'll use any method in order to get what he wants, namely defeating Guy. This is very likely no small part of Michael's corrupting influence.

Likely because he's seen many Demon Lords rise and fall under Guy's banner, he has a tendency to look down on everyone except Guy himself and the 4 True Dragons. He doesn't think much of Rimuru, who has been active a short 3 years at most, but he's sure he'll have to send Velgrynd to deal with Ruminas.

Background
Rudra and Guy have been at odds with one another for well over two thousand years. He actually named Guy and befriended him over the course of their battles. They fought nearly as equals with Rudra being slightly weaker but more cunning.

He has been suppressing Justice King Michael from going out of control and has nearly reached his limit and would be unable to keep his promise with “Star King Dragon Veldanava. His original agreement with Veldanava was that he would use Ultimate Skill Justice King Michael in order to unite all humans together. But if he failed, the skill would then eliminate all intelligent beings. Veldanava recognized the self-destructive nature of intelligent beings.

He had asked Damrada to seek out someone who could defeat Justice King Michael before it went berserk.

He had ordered Kondou to kill him if he was no longer able to suppress Justice King Michael.

Abilities
In his prime, Rudra was an awakened Hero with strength nearly equal to Guy Crimson. While Guy battled with his overflowing power and skills, Rudra fought him as an near equal with the pinnacle of skill and technique. Over the course of their many duels, all of them ended up as stalemates. Even when Rudra was slowly being overpowered after countless battles, he managed to force a draw by pulling small tricks every so often. Even after Guy had grown stronger over the course of time, the Fake Rudra who had perfectly reproduced the strength of Rudra in his prime was still able to fight him equally.

He was so strong that he had clear chance of defeating Guy Crimson in their first battle had he fought with his full power and not named him. Despite the fact that Guy already possessed the Ultimate Skill Prideful King Lucifer at that point.

However due to Rudra's countless reincarnations, his holy powers were shaved off and he lost his qualification as a hero. Despite that he remained a Human Saint through the sheer force of his will, and he is still considered to be one of the two beings within the empire who possesses absolute power with the other being the Scorch Dragon Velgrynd.

Quotes

 * 「Oh ho? So you came here noticing your owner was stolen? Fool. With the your source of power, your master Veldora, gone, even for a Demon Lord, you’re now just a simple monster. Coming here without a single underling,  it seems you don’t possess a shred of intelligence . Make haste, and  rid me of this fool! 」(Rudra's Comment toward Rimuru's Naivety).


 * 「No way, why? Why, did the effect of my Regalia Dominion…. my “Sovereign Rule” disappear? 」

' It was just a lowly Demon Lord, a puny slime! ' It should have become powerless, after the source of its powers, Veldora, was taken away…. How, could it consume it’s master, and take that power for itself!! I was this close to finally achieving victory against Guy!! To get in the way of my plans…. Unforgivable,  you lowly Demon Lord !!」(Rudra's Reaction after Rimuru Took Back Veldora from Him).
 * 「 Why, was Veldora defeated?!
 * [Impossible, that’s just impossible!
