Demon Slayer's Tengen Uzui is considered to be one of the weakest Hashira due to almost losing this fight, but the fact is that Tengen only looks weak when compared to the most overpowered Hashira.
8 Shinobu Kocho, The Insect Hashira
That being said, she's arguably the weakest Hashira when it comes to pure strength.
people also like to say tengen is weak because he had trouble with "upper moon 6" gyutaro was stated to be stronger than what his place would seem because daki holds him back.
In terms of physical strength, Tengen Uzui is far from being the weakest Hashira. While his feats throughout the Daki and Gyutaro battles certainly displayed this, there's additional evidence to show that he's not the weakest Hashira.
He is the fastest, but however, he is not the second strongest Hashira. The strongest Hashira is Gyomei while the second strongest Hashira is Sanemi. Tengen does have impressive feats such as his death battle with Gyuutaro, but all the Hashira except Shinobu have stronger feats.
Shinobu Kocho (The Insect Hashira) While we don't necessarily think Shinobu Kocho is physically weak by any means, we do believe that she is currently positioned at the bottom of the totem pole compared to her fellow Hashira members.
Sanemi's blood is known to be enticing yet intoxicating to Demons, which he used to bait and stab Nezuko. Sanemi is clearly the least popular Hashira among Demon Slayer fans.
Zenitsu Agatsuma
Zenitsu and Tengen growing angry at each other. When the two originally meet, Zenitsu develops a disdain for Tengen after he attempted to kidnap the girls of the Butterfly Mansion, and due to his flamboyant personality, even referring to him as the "god of idiots."
1. Gyomei Himejima. Gyomei Himejima, the Stone Hashira, is the strongest Hashira in the Demon Slayer corps in terms of strength and swordsmanship. He is the only person who uses spiked flails and an axe instead of standard swords to kill demons.
Rengoku's fight in the Mugen Train arc showed his incredible speed and reflexes. He was able to match Akaza's speed, and his movements were so fast that it was almost impossible for the naked eye to keep up. Tengen, meanwhile, is the fastest runner out of all the Hashira.
He would be disoriented by the shockwaves created by Akaza's blows. Tengen has anti-demon bombs that can disorient them for a short period of time, but this wouldn't be an effective strategy when Akaza uses Compass Needle, which allows him to accurately pinpoint and aim for his opponent's weak spots.
During his battle with Gyutaro, Tengen used his muscles to stop his heart to temporarily prevent the poison from circulating, which let him get the drop on Gyutaro who believed he was dead.
Killed And Was Killed By Doma
Before arriving at the Infinity Castle, the Insect Hashira consumed roughly 81 pounds of wisteria poison. Even though Doma killed her, he died just as quickly because of the sheer amount of poison he ingested after eating her.
1) Shinobu Kocho
The Insect Pillar of Demon Slayer Corps, Shinobu is undeniably the smartest individual. She might not be physically stronger than others, but her intelligence is what kept her going.
In the eighth episode of the "Entertainment District" arc, Upper Six Gyutaro couldn't stop gushing over his man-crush on Tengen.
Being the flashy and flamboyant man that he is, Tengen has become one of the best and most memorable characters in Demon Slayer. He had a rough start when meeting Tanjiro as Tengen was one of the Hashira that thought he and Nezuko should be executed, but the two of them have come to respect each other.
Tengen Uzui
He is the fastest Hashira, and the second physically strongest. Obviously, then, Tengen Uzui is rather proud. He is demanding, fussy, boastful, and prone to selfishness.
The Water Hashira, Giyu, survived the "Infinity Castle" arc after fighting beside Tanjiro against Akaza and Muzan.
1) Muichiro Tokito. Mist Hashira Muichiro Tokito was the youngest Hashira, and yet, possibly the bravest of them. Interestingly, Muichiro and his brother were also descendents of Kokushibo, and thus directly related to Yoriichi as well.
When it comes to pure strength, Shinobu Kocho is the weakest Hashira in Demon Slayer.
Mitsuri is a voluptuous young woman with a kind face. She has pale green eyes with small moles under each eye. Her most defining feature would be her long hair usually tied in three braids which is pink and fades into neon green halfway through.
The secret to Gyomei's powers is that they are governed, regulated and enhanced by his emotional capabilities. So in a sense, his crying is a sign of his strength rather than weakness. As a gentle giant, Gyomei's character can be seen as a deconstruction of what makes a person strong in Demon Slayer.
Giyu was the first Hashira to be introduced in the series, making his debut in the very first episode. After rescuing Tanjiro from the newly transformed demon Nezuko, Giyu prepares to execute her as he would any other demon.
