I’ll assume you’ve seen the most popular ones (Big Three, Dragon Ball) so I’ll recommend the others; Solo Leveling, Ninja Kamui, Kaijuu No. 8, Spy x Family, Black Clover, Fullmetal Alchemist Brotherhood, Black Cat, Death Note, Yu Yu Hakusho, Dr. Stone, Hunter x Hunter.
An old time classic that I find myself rewatching is UFO Robot Grendizer (a sequel to Mazinger), and don’t watch the reboot… it’s not that good…
I’d recommend trying the sports genre; classics like Slam Dunk and Captain Tsubasa and Hajime No Ippo, and from the new ones Inazuma Eleven, Blue Lock, Haikyuu, Kuroko’s Basket
