No. That goes to Bakugo who acts like a constant entitled ***** for nearly 4 seasons. I've seen worse, but not by much comapred to Bakugo. To keep the list towards just anime's whiniest characters, we have:
- Asuka Langley Sohryu
- Shinji Ikari
- Lyserg D.
- Those 3 brats from Eureka 7.
- Kagome Higurashi and Kikyo.
- Boruto
Second, characters similar to Bakugo have already been done better. What's more, this character is the main character from anime over 20 years ago.
Yu Yu Hakusho. Yusuke "Motherfukin'!" Urameshi! Hell, 3/4 of the boys are all better versions of Bakugo or Vegeta. Yusuke and Kuwabara are nicer and better versions of Bakugo. Though if you wanna be technical, Yusuke was a bigger jerk than Bakugo at the beginning, but he did not always act like an entitled brat. Nor felt the world constantly owed everything to him. Hiei has always been the better Vegeta. Another jerk character that's done right is Ren Tao from
Shaman King, and Zuko from
ATLA. Either are better people and more sympathetic than the egotistical dick-wad known as Biatch Bakugo.
Also, most teens around his age or older can either kick the shit out of Bakugo at their weakest. Or, are on more than even footing with the douche.
