In terms of crossovers. and I mean official crossovers only, no unlicensed cameos or any of that kind of thing. Fortnite definitely made this easier by crossing over with both DC Comics and Marvel. And we could just s easily do “6 degrees of DC”, but we’re going Fortnite right here. It also crossed over With Star Wars, which I guess easily allows us to bring in the few franchises Star Wars has crossed over with. Indiana Jones, The Muppets, Soul Calibur, Tony Hawk pro skater (even if we could just as easily use Spider-Man for the connection)

So, lets start with another big video game, Pokemon

Pickachu was in Smash with Ryu >>> Ryu fought alongside Wolverine in the MVC games >>> Wolverine was in Fortnite

We could also connect it with some anime from there. Neon Genesis Evangelion for example.

A couple Evangelion heroes fought Godzilla >>> Godzilla fought The Avengers >>> The AVngers in Fortnite

We could do something weirder with the Marvel connection, like Webster.

Webster met Worf >>> Worf Met Wolverine >>> Wolverine was in Fortnite

We could try some connections by other means.

Generator Rex crossed over with Ben 10 >>> Ben Tenyson was in OK KO! With Raven >>> DC Comics crossed over with Fortnite

Lets try something a bit deeper. Lets connect Fortnite with Honey Nut Cheerios

Buzz Honey was in a commercial with Grumpy Cat >>> Grumpy Cat was in a comic series with Garfield >>> Slimer and Garfield were both in Cartoon All Stars to the Rescue >>> Ghostbsuters crossed over with Fortnite

Fortnite also crossed over with Halo which crossed over with Forza Which connected with major film franchises like James Bond and The Fast and the Furious

I think it’s actually surprisingly hard to find a franchise that doesn’t eventually. I’d actually be interested in anybody who could find a significant media franchise that wouldn’t cross over with Fortnite in 6 connections or fewer.
