“I’m sorry, Dave, I’m afraid I can’t do that.”

From Metropolis to Ex Machina, cinematic robots have proven themselves to be formidable friends or foes. NOTE: For the purposes of this list, "robot" is defined loosely to include automatons, androids, and any machines capable of artificial intelligence. Feel free to yell about this in the comments.

The Iron Giant, The Iron Giant (1999)

Sure, he looks imposing, but the Iron Giant sacrifices himself to save a town from certain doom. He also befriends a lonely 9-year-old boy, which is really just going above and beyond.

Warner Bros.

Baymax, Big Hero 6 (2014)

Baymax's sole purpose is to help people — he's literally a health care companion. He's also super snuggly and comforts Hiro after Hiro's brother Tadashi is killed. What could be more healing than a robot hug?

Walt Disney Studios Motion Pictures

C-3PO, Star Wars (1977)

He may not set out to fight alongside the Rebels, but he definitely does his part. Speaking multiple languages and facilitating human-cyborg relations are useful skills to have, even if he is a little annoying at times.
