Amusingly, there is a fanfiction, I think currently abandoned, of Thanos, the Marvel Comics supervillain, visiting Equestria. And Twilight Sparkle is absolutely fascinated by him, and keeps asking him what he considers to be stupid and annoying questions. But he can’t just leave–he’s there with his girlfriend Death, who is visiting Equestria on vacation…
“You know nothing of my needs, beast…”
“Oh, that’s not what I meant. I said I need it…. More than you. Bye!”
(Cue immense magical explosion.)
Yeah, that’s Megatron.
