Yes, you can. The Gamera and Ultraman Wikis are connected to this one because they all are hosted by Wikia.com, so they all share the same core database.

Unlike non-Wikia wikis like Wikipedia, Bulbapedia, etc., who aren't connected and need separate accounts, Wikia is connected and only needs one account.
