Aidan Gallagher is a cute, nice, and caring boy. He starrs in the Netflix Series Umbrella Academy, as Five. He also worked in Nicky, Ricky, Dicky, and Dawn, playing Nicky Harper. He is amazing at acting, and plays the mean, bratty, and jerk figure of Five super well. He is a vegan because he cares about animals a lot, and is all about saving the world/environment. He uses his social media to promote helping the environment as well. Did I mention he's a total cutieeeeeeee?
Person 1: Oh wow, that boy is cute!
Person 2: But not as cute as Aidan Gallagher ;)

Aidan Gallagher could be a lil' cutie patooty, but when we see him as Five in Umbrella Academy, we see that he's also hot af! If you meet an Aidan Gallagher with an ax you better stay away. If you meet one singing, run for your lives. If you meet one smiling and staring, look away from that hypnotizing glow. If you see an Aidan Gallagher alone, normal, you better give him your number before his mob of fans, that are 13 year old girls, come and attack him. Aidan Gallaghers are hotties, cuties, usually famous, magical and their voices will make you shiver out of fear. Be careful the next time you approach an Aidan Gallagher...
EXAMPLE 1
Person A: Why are there so many young girls?
Person B: Oh, it's just that there's an Aidan Gallagher here.

EXAMPLE 2
Person A: Owww my ears are soo sore. I have such a bad head ache!

Person B: Did an Aidan Gallagher sing?
Person A: Yeah. Owwww.
