Toby Fox Effect 

(Alternate definition)
From TVTROPES:
“With the release of Chapter 2, the fandom has noticed a pattern where Toby Fox includes a character who happens to be Tall, Dark, and Handsome compared to the rest of the cast (Mettaton, Rouxls Kaard, Swatch), but the fandom always lusts after the short, memetic, superboss instead (Sans, Jevil, Spamton).”

“Why is everyone lusting after that guy? This guy's so much hotter?”
“Toby Fox effect.”

Toby Fox Effect 

A phenomenon when members of a fandom forego the meaning or message behind a story, sometimes even behaving the opposite way the message intended.

"Sometimes Steven Universe fans can be really toxic. It's the Toby Fox effect in play."
