In order not to have sci-fi and fantasy shows skew the matrix, we do not add every ‘alt Earth’ character to the database. A character may be added if they fall under the following situations:
- The alternate character has at least one episode wherein they are a fully fleshed and separate character from the mainstream (example: Ezri Tigan from the Mirror Universe)
- The alternate character moves to the mainstream world (Laurel Lance from Arrow)
- The alternate character is of significant plot importance
If the Alt Character does not pass those tests, then their information should be added in the main character’s biography.
