Also I can’t recommend the Animorphs series enough, definitely a latecomer to the series as an adult but holy hell does it contain just the right amount of existential terror I can appreciate
“One of my enemies has taken over my head and most of my bodily functions, now I have to have my friends restrain me in an isolated cabin in the woods until the thing inside my head dies”
“We recruited an ally and he’s more of a loose cannon than OUR loose cannon”
The Team Goes Back In Time And Kills Hitler
“He’s Hitler, he dies, end of story”
Birdboy gets a big +1 in my book
