I love Uran a lot, she’s super cute, I never got too into atlas but I think his questionable relationship with Livian is a delicious addition, and Reno is also so so cute, he’s just a silly guy.
I might take the easy way out and say my least favorite Atom is the one from the 2009 movie Astro boy 😭 it’s such an ugly movie and I hate it so much. It doesn’t help that the casting made it seem like a promising movie, but it fails on all accounts. Atom isn’t cute at all in it. Whenever I talk to people in person about Astro boy they only know the movie and it makes me sad!! They don’t get to see how cute Atom normally is ☹️
