For these, I have never been able to get into superhero comic books, which make a bulk of the popular ones because they feel too silly to me now. From the ones I have read, and I haven’t read too many, I really liked Sandman (Gaiman) and Hellboy (Mignola).
My favourite of all time is Transformers: More Than Meets the Eyes. It’s extremely hilarious and the characters seem very relatable.
I have not tried getting into manga too much. There’s this one that I have read about a robot destroying other robots but I forgot its name. I tried reading a horror one about spirals (it’s quite popular) but couldn’t get into it.
