There are reason why heroes are friends with characters from another franchise. And i would like to explain it to those who don’t know the reasons for it.
Mickey Mouse/Jack Skellington
Reason: Mickey and Jack are both loved by everyone that know them and are considered celebrities in and out of their universes. They also have a knack of getting into trouble despite being well-meaning wheither it’s created a twisted Christmas or just having a enchanted broom fetch water. They are rarely seen without their faithful dog companions: Pluto and Zero. But above all else, Mickey and Jack share creativity and optimism that is really contagious and are not afraid to do the right thing.
If there is anything i missed, just let me know.
