Not having knoweldge of a character or franchise is completely fine, the problem is people who say "LITERALLY WHO?" to dimiss a character they don't know about, calling a character from Elden Ring and League of Legends a "literal who" in this scenario would be even double stupid because those games are very popular and i'm sure it will happen if they get in, since as

said there were people calling Kazuya one and i even saw people call Sepiroth a literal who.
Also in some cases people know the character, but still use "LITERALLY WHO?" to be obnoxious and toxic, i really dislike the term lol.
