Zenitsu is generally a coward, but he was not a coward when he protected Nezuko. He was hurt, but he still protected her.
This was the first moment in the series when the powers and strength of the Hashira were shown in the series.
Muzan's first appearance was quite powerful. Although he met Tanjiro in a crowded city, he managed to scare Tanjiro.
Despite the fact that Sanemi hit her and was bleeding, she didn't hurt or attack him.
When he's awake, Zenitsu is cowardly. However, when he sleeps, he becomes badass and powerful.
Although Shinobu died, she managed to poison Douma to the extent that he was killed.
Kokushibo acknowledged Gyomei's strength. He called him the strongest swordsman he's met in many years.
Haganezuka didn't fight Gyokko, but he managed to wound his ego when he worked on his craft despite Gyokko's incessant attacks.
This was the first instance where Nezuko's potential as a demon was properly shown. She obliterated the upper moon 6.
Yoriichi, with a single strike, managed to scare Muznan to the extent that he went into hiding.
