There was a Fortnite crossover event a little while back, that's probably why

More likely because of the hundreds of items, cosmetics, and other references over the past 3 years

^ No, those would just be on the Fortnite wiki

The only reason there's an actual Fortnite page on the Star Wars wiki is because canon info was revealed in that Fortnite crossover event

Skins and cosmetics and emotes are just shout-outs that don't need a spot

More specifically, the fact that Palpatine was alive

Makes sense

why does Vader have a crotch pad in Fortnite even though he actually doesn't in the other media(movies, shows, books, etc)

^He does though.
