I think the only anime i watched was JoJo's bizarre adventure and holy it was super super good! I would really recommend it if you haven't seen it!!

DR Stone is pretty fun! It's a Shonin anime about a high school genius doing whacky science stuff in a Stone world! No inner monster trope but its a favorite of mine personally.
Maybe not anime but the Midnight Gospel is also really cool! Though less action adventure and more Buddhist and Hindu Philosophy stuff in a very cool visual style

I've seen Midnight Gospel around, correct me if I'm wrong but isn't it like a mature show or something?? I saw it's from Adult Swim

Yeah its definitely a mature show and does talk about and depict some mature content so that may be a bit of a scareaway if you aren't prepared for that.
I think what the show talks about outweighs that personally though, thats just my opinion

Avatar, la leyenda de Aang y la secuela: Korra

Jaja justo hace una semana me jalé todo Avatar y Korra y hasta los comics xD

Thank you for the suggestions!

Ancient Magus' Bride is one of my current top 3 fav animes

That Time I Was Reincarnated As A Slime, it's really cute and is a good ol isekai with lots of fantasy action :D

I've seen it around, I might check it out!

Adventure? Hunter X Hunter is my first thought.

Already watched :D one of my favorite animes
