Tomias is a surprisingly complex charactor, having created him when I was about...15, when my imagination was just running wild everywhere (it still is for somer eason XD). He started out as a charactor on this RPG website, based around the Redwall Saga by Brian Jaques, on this site, you got to play as one of the 'vermin' creatures, and I chose a fox. However maybe 5 months after I first created him, me and one of my best friends from the site started doing insta RP's over Skype and MSN and such. Due to both our love for the X-Men comics/games/movies/whatever, the whole RP was based around that, so I made a partially different version of Tomias for that, which due to it being more like me irl, this is the version that became my actual fursona. Since, a teenager that mutates into an anthro fox with telekinetic abilies hasn't been done yet...I think XD
Anyway, as a charactor, I'd say this 'updated' Tomias is pretty pliable between different fandoms, and different universes. So far, here is a list of all the fandom/universes that I've rp'd him in, that I can remember so far.
-Lilo and Stitch (don't ask)
-X-Men
-The Road To El Dorado (again...)
-Stargate SG-1/Atlantis/Universe
-Doctor Who/Torchwood
-Once Upon A time In Mexico
-Pirates Of The Carribean
-The Secret Window
-Alice In Wonderland (the new one, with Depp in it)
-Aladdin (okay fine, me and my friend love animated shiz)
-My Little Pony: Friendship Is Magic
-Homestuck
-Avatar: The Last Airbender
-Pokemon
-Halo
-Zombie World (the Romero version)
-K4 (A massive scale self created universe me and a whole group of bros rp in)
-Red V Blue
-2012
-Battle: Los Angeles
-From Hell
-many other random/generic/made up shit
Yeah, you get the idea...I RP too damn much :V But yes, as you can see Tomias is a great charactor to RP with, since he fan fit in easily enough with almost anything you put him in. Hell, I even have a human version of him I use for some RP's, and a different alias, called Michael Vulpes, since Tomias Redford was sorta, getting overused.
