To conclude, Nezuko is a formidable powerhouse within the anime and is probably one of the strongest main characters in the series. Her traits make her highly desirable to Muzan, as he is still attempting to track her down.
Nezuko is easily one of the most powerful demons in the Demon Slayer series, possibly due to the large quantity of blood she was given by Muzan. But what makes her a truly terrifying opponent is her willpower, being the only other demon after Tamayo to escape Muzan's control.
Nezuko, after she became a human again, lost all her powers. This includes her size manipulation, superhuman strength and regeneration. As of the end of KnY, Nezuko is as strong as an average human.
There is no doubt that Nezuko is faster and stronger than the base form of Tanjiro. However, he can activate his Demon Slayer Mark and happens to be a user of the Breath of the Sun. This gives him an edge because it is one of the series' strongest and most efficient breathing techniques.
Nezuko doesn't stand a chance against the Upper Moon 3
Nezuko is undoubtedly a strong demon in Demon Slayer and she proved her strength repeatedly. One situation that really displayed her true potential was the fight against Daki. She underwent a transformation and thoroughly overwhelmed the Upper Moon 6 demon.
It is theorized that Nezuko was able to conquer the Sun because she comes from a lineage of Sun Breathing users and because she kept a big part of her own humanity i.e. because she never ate human flesh.
Nezuko's most significant trait, however, is her immense growth, which is likely due to a combination of the amount of blood she received from Muzan and her willpower. To conclude, Nezuko is a formidable powerhouse within the anime and is probably one of the strongest main characters in the series.
Despite not being a member of the Twelve Kizuki, Nezuko is a very powerful demon. Her most prominent traits is her extraordinary growth rate possibly due to the high amount of blood she received from Muzan.

Apart from Tanjiro, the show centers on his younger sister Nezuko Kamado, turned into a demon by Muzan Kibutsuji. Demons are incapable of walking out in broad daylight because the sunlight will burn them into the ashes. However, Nezuko has immunity against the sun, so she was given the name “The Chosen Demon”.

By far, this is Nezuko's most damaging technique when it comes to fighting her own kind.
Abnormal Demon Physiology: As the "chosen demon", Nezuko has several unique demonic traits that set her apart from all other demons. Most notably, Nezuko can continuously restore her power without consuming any human blood like any other demon would need to do.
In episode 6 of Demon Slayer season 2, Nezuko entered a berserk state to protect her brother Tanjiro, causing her body to develop into that of an adult. She loses her gag, grows a single horn and gains vine-like patterns across her body.
Nezuko might be a terrifying demon, but she's also one of the cutest characters in anime. There is absolutely no doubt about the fact that Nezuko is the star of the Demon Slayer anime.
Muzan, the King of Demons, is the strongest and also the primal demon in the world of Demon Slayer. Consuming his blood is enough to turn you into a powerful demon. He can control all the demons in existence, with only people with strong willpower like Nezuko being an exception.
Muzan Kibutsuji
Just like Tanjiro, Nezuko shows nothing but hatred towards Muzan. During her battle with Daki , she regained the memories of when Muzan killed her loved ones which convinced her to kill one of his followers as well.
Master Swordswoman: As a member of the Hashira, Nezuko is one of the most powerful and skilled sword-users in the entire organization. Nezuko is a highly skilled master-level swordswoman, having been trained since birth to be able to defend herself using a katana.
Nezuko would practically be unstoppable in the series for the following reasons: Nezuko has conquered the sun, meaning she can eat humans both daytime and nightime. Meanwhile, other demons can only eat humans at night. After immunity to the sun, Nezuko would regain her intelligence and speech when she was human.
Thus, Muzan created demons for hundreds of years even when he didn't want to turn someone. Since he didn't know anything about the Blue Spider Lily medicine, he needed others to find the plant for him by happenstance. This is the general reason why Muzan turned Nezuko into a demon.
Muzan had attacked Tanjiro's family and shared his blood with Nezuko.
Well, there are many reasons for nezuko's cuteness. She shrinks, she lives in a box like a cat. She plays cute little games when she's bored. She loves giving and receiving pats on the head.
Nezuko has several powers, including regeneration, superhuman strength, growing and shrinking rapidly and a blood demon technique called Exploding Blood (爆血, Bakketsu) that causes her blood to burn once it leaves her body.
