I don't draw other people's characters very often, and I generally advise other people not to either, because, unless you're actually being EMPLOYED to do so; you're not getting anything out of it. You're not promoting yourself or your own ideas but giving a big company free advertising. You're spending time and effort cementing someone else's IP into the public consciousness when you should be doing the same for your own.
That said, messing around in worlds that you did not have a hand in creating is a lot of fun. I do it myself and feel very guilty for it because I should really be focusing on my own.
These fanfiction concepts include:
A massive crossover of science fiction universes that sees Star War
’s Empire and Star Trek
’s Star Fleet fighting above the titular construct from Halo
….which has been overrun by Daleks.
A Sonic the Hedgehog
origin story, charting the arrival of Dr Robotnik.
A Teenage Mutant Ninja Turtles
tale that focuses on Splinter’s early years.
My take on the Batman
universe, which attempts to make the Dark Knight appear more nightmarish and scary. Roger Ramjet
…. I’m not saying anything more, but I have an idea that'll turn it from a goofy old cartoon into something that kicks ass.
And finally, a rewrite of Kingdom of the Crystal Skull
, which drops certain characters and adjusts the motivation of others (Aliens and refrigerators remain).
The chance of me actually getting any of these to any stage of completion is very slim, but I’ve created a new poll because I’m curious to know which you would be most interested in seeing fleshed out, even if it's only a little bit of concept art.
