Genius combat intelligence vs Extraordinary Genius combat intelligence
Cecilus's Extraordinary got accepted and even without that Reid upscales from Ley Batenkaitos who is also an extraordinary genius

Like
Extraordinary Genius in regards to combat (Kenshiro stands as the single most skilled fighter in his setting, surpassing
all his predecessors and having absolute mastery over every single martial art displayed throughout the series. He has uncanny precision,
Same with reid
to the point of being able to
strike a pressure point as small as the tip of a pin with a strand of hair. His memory is refined to the point that he's able to memorize up to 50,000 words after reading them once. His technique and grace are unrivaled.
Cecilus can hold a sword and do 100s of millions of swings in his mind, swinging for literal years and then he can grab that experience from his thought and apply in action. In the middle of a fight. As a child.
Theresia level shit, she held a sword for the first time and instantly mastered it. From that point on anybody who used any kind of combart arts She could only see mistakes, openings and counters, they could be the greatest master swordsmans, axe wields, world renowned archers, assassins, the greatest martial artists etc. She was so skilled that in her vision she could see see the perfect line that if she followed would imminently kill her opponent in a single hit.
This same Theresia got one shot by Reinhard against whom she showed her most perfect sword swing ever. Reinhard has been stated to be an eternity of training above her. Reid upscales from Reinhard
He can copy and adapt to incredibly complex techniques on the fly, such as when
he adapted to Anryū Tenha's space-warping ability,
Emilia and Ram in the witch tower could do the same and they are not even Theresia level
Again, Ley Batenkaitos is the Gourmet of Gluttonies and has eaten over 10,000 transcendents. None of those 10,000 are fodder. They are all masters of their field, the greatest sceintists, martial artists, master swordsman etc.
He is the ultimate culmination of them and he is still not even close to Reid
after only seeing a single move of said style or when
he managed to fight Raoh to a standstill and would have killed him had he not been stopped, despite
Toki stating only minutes prior that
Ken didn't even have a 1% chance of defeating Raoh. He's stated to have
"infinite potential" in terms of technique and combat prowess multiple times throughout the series.
yeah same with Reinhard and Reid
Scales significantly above
Toki, who, with his sheer skill and talent,
bent Raoh's fate and manifested his harbinger of death. Shown multiple times throughout the series to be capable of demolishing entire armies all by himself, stated by enemy soldiers to "
march calmly, unstoppable, through thousands of soldiers like he was in the middle of an empty field", casually crushed both Falco's and Jakoh's armies at the same time.
a 9 or 11 yr old cecilus decimated 10s of thousands of his enemies and only stopped because he ran out of people. I think he was also specificied to not kill his enemies? Anyways, he had the ability to not only decimate entire armies but even towns, cities, and even countries.
Even before his final fight against Raoh and achieving Muso Tensei, he was unfathomably above combatants such as the Red Berrets,
who are each capable of defeating 500 soldiers at the same time, and defeated their general with his eyes closed.
Elsa can target your vitals while all of her senses have been cut off and her mind was floating in a void.
In that same fight, Ken states that due to the nature of Hokuto Shinken's transmission,
it's like he has 1800 years worth of combat experience and training, he was an assassin from the very moment he was born. Hokuto Shinken's very nature is of one adaptability and
it has infinite fighting variations in order to overcome every obstacle and opponent, no matter the difference in strength)
Ley above + Reid is an eternity (literal infinite amount of training) above Theresia (qn unfathomable skill god) who has also been stated to be an eternity above the rest of the verse.
