Geralt is but the tip of the iceberg. There are plenty of Witchers just as powerful. Here are a few powerful Witchers who could rival Geralt of Rivia in terms of power and strength.
Vesemir
Vesemir has a unique advantage none of the other Witchers possess. He has lived on to an age of more than 600 years. That is a feat Witchers in general courtesy of their profession, do not get to accomplish. Vesemir’s other feats and accomplishments are way too many to count. He survived the dreadful attack on Kaer Morhen. Many Witchers from the School of the Wolf were wiped out but the seasoned Vesermir survived. Not just skills, Vesemir is a Witcher who is equally knowledgeable, a brand of experience you seldom get to see in the Witcher universe.
Letho
The Witcher known as Letho of Gulet hails from the School of Vipers, the most mysterious of all schools. Letho of Gulet was tasked to lead a band of Witcher assassins to kill kings, sorceresses, and high ranking nobles in the Northern regions, spreading chaos. Standing at about 6 feet tall and weighing as much as 300 pounds, this guy is the Witcher version of a tank. His arms are thicker than the average human torso. He is a tough nut to crack even for Geralt of Rivia. That’s the reason why Geralt actively tries recruiting Letho to aid him in his battle against the Wild Hunt.
Lambert
A relatively young Witcher, Lambert still has ways to go. But that does not mean he is less skilled. He proved himself in battle when the Wild Hunt attacked kaer Korehn. Teaming up with Geralt, we perhaps got the best action sequence ever in the Witcher Universe. Lambert is someone who is acknowledged by even Geralt for his battle skills so we will admit he is one of the strongest Witchers to ever exist.
Eskel
Eskel, just like Geralt, was trained by Vesemir, another super strong Witcher whose feats are the stuff of legends. Eskel may not be as popular as Geralt but he possessed one of the strongest magical auras of all Witchers. Known to be strong and reliable in battle, Eskel battled the Wild Hunt in Witcher 3. of all the Witchers that took part in the battle that day, Eskel stood toe to toe with Caranthir, one of the fiercest fighters of the Wild Hunt. That alone speaks volumes.
Erland
Erland of Larvik is the founder of the School of the Griffin, one of the most ancient Witcher Schools ever. Erland took thirteen of his followers to found this school that trained Witchers in the original noble ways every Witcher was originally created to follow. Despite leaving the Order, Erland enjoyed widespread fame and even served as a counsel to many Kings and Queens. He and his Witchers continued to hunt monsters like the Cyclops of Ard Skellig. Many rulers began to grow jealous of his growing power and influence and attacked the school’s headquarters. Erland was not there when the attack happened but he wrote everything he knew in a journal, hid it in a cave, and went into hiding. Nobody knows his whereabouts.
George
The Witcher known as George of Kagen does not appear in any of the games or the show. He is mentioned in GWENT: The Witcher Card Game. A disciple of the School of the Griffin, Geogre of Kagen was a legendary Witcher known for his battle prowess. An expert in magic, George was killed fighting a green dragon. The only reason he was killed was because he only took one sword to that battle and forgot to take the diagram of the new silver sword that could have easily killed the dragon. George of Kagen defeated a dragon with one ordinary sword. He is indeed strong.
