- 6 other unknown realms
- 57. "Enkrypted"
- 110. "Under Siege"
- 112. "Vengeance is Mine!"
- 113. "A Cold Goodbye"
- 114. "The Never-Realm"
- 124. "The Kaiju Protocol"

- Apparently, the color of the portal depends on which realm you travel to, because when you travel to Ninjago, it is a brown color and when you travel to the Never-Realm, it is white.
- It depends on which method you open the portal to a realm, the way to get there is faster or slower, since if you use the Traveler's Tea or the Realm Crystal, a portal will open and you can pass without difficulty, while with others it takes to go to the realm.
