Ok so in LEGO Dimensions Kai and Chen (and some nindroids and others) end up in other dimensions right? Well this never happened in the TV Show so my theory is that The Sixteen Realms and Ninjago are held in the multiverse and that the Ninjago shown in LEGO Dimensions is a parallel Ninjago Universe to the normal one. Even though the Ninjago Universe shown in the TV Show isn't shown (Only the parallel one) that doesn't mean that in LEGO Dimensions it doesn't exist. So for now The LEGO Multiverse page isn't invalid just unconfirmed and untill further notice no one please edit the page.
