I’ll start off by listing mine:
The T-800, Terminator 2: “I know now why you cry, but it’s something that I can never do.” Gets me every damn time.
ADA, Zone of the Enders: I think I’m the only one who played this game more than the MGS2 demo that came with it. I will never not laugh at the exchange of “You may speak like a human, but you’re still a heartless computer, aren’t you?” “That is correct. What is the problem?”
Codsworth, Fallout 4: He survives the nuclear holocaust despite not having a bunker and waits 200 years for you to come back. When you look at what changes his relationship with you, he mostly just wants you to be nice to people. I never swapped him out as my companion.
B.O.Y.D., Ducktales 2017: He’s adorable. 'nuff said.
VEGA, from DOOM 2016. I think he’s one of the most realistic depictions.of how an actual general AI would act: he calmly walks you through the process of initiating his self-destruct sequence when ordered to, and even gives you helpful tips on how to do it more efficiently.
Doom Slayer is such a bro for making a backup copy of him.

Hayden banking on the Slayer doing that so that he could use VEGA in his plan to bring back the setting’s god figure, threw me out of the loop for a while.
