Hi Spencerz! My name is Marcus, and I'm the Fandom Wiki Manager assigned to this fine database. My job is to help the community by being liaison to full-time Fandom staff (no takeovers by staff or anything). If you ever have a question or issue relating to the wiki, editing, etc., feel free contact me on my message wall. I've already contacted a few other admins. If you have any further quesstions about my role as a wiki manager, don't hesitate to ask!
In Marvel's Agents of S.H.I.E.L.D., the computer simulation called the Framework generated a full alternate reality of Earth-199999 where Hydra has replaced S.H.I.E.L.D.. I've noticed this hasn't received it's own TRN or anything and all of the characters existing within this reality are instead listed under Earth-199999. Should this reality receive it's own TRN or be left as it is? Thanks
Back in 2013 it was already suggested that Phineas and Ferb: Mission Marvel should be assigned it's own Temporary Reality Number, so that the Marvel Characters appearing in this episode can get their own articles. That is of course assuming that the episode is set in it's own, seperate reality and is not part of an existing Earth or TRN. Why hasn't this been done yet?
The earth/reality of the X-Men films (both Earth-10005 and Earth-TRN414) are not the same/connected to the earth/reality of the MCU-films and tv-shows (Earth-199999). Main reason it's so has to do with film & tv rights, where Fox owns X-Men & Fantastic Four and its related characters, while Marvel under Marvel Studios has reclaimed everything else in terms of rights to their own characters.
