I haven't done much RP'ing lately but I had a different method for each character--

For the 3rd and most recent Sid Feder character who has the Waylon Mercy picbase I would try to think of scenes from Cape Fear or watch old Waylon Mercy vignettes, mixed with some random touches of off the wall humor.

For the 2nd Sid Feder character who was very short lived and had the Magnum P.I. picbase I would listen to Van Halen and Def Leppard and watch old episodes of Baywatch.

For the original Sid Feder with Brian Pillman picbase I'd just open up anywhere from 2 to 4 blank documents at once and start writing different scenes in each because I had endless stories to touch on from different parts of his past and what developed him into who he became -- a complete psycho on the outside but with a burning passion like no other when it came to wrestling and his family. I'd literally jump between them every few minutes and just add to them; one page where I'd be writing scenes involving he and his crazy wife, Flo; another open that may have related to another family member or his father; another page just relating to any random current scene or adventure he may be going through. Then I'd piece them together so each RP contained small portions from each and keep telling those separate stories over time. I don't know why it was so easy with him. Sometimes old clips of Brian Pillman would inspire me when it came to the more crazy stories or trash talking. Pillman's ECW appearance is full of great inspiration.

For Mister Mystery with Jason Voorhees picbase I'd just think of or watch sickening horror scenes from old movies I loved -- Friday The 13th of course, Nightmare on Elm Street, the older Halloween movies. Then I'd try and adapt those feelings into what would happen if that kind of sick fucker was in a wrestling promotion and knew he was being filmed, and enjoyed displaying vile acts and talking shit to people.

When Mister Mystery was revealed to be Original Sid's father and renamed Poppa Feder, I pretty much lost inspiration and just reverted to trying to think of him as being like Goldberg.

When I was the Headless Horseman -- later revealed to be Original Sid in disguise so he could do a surprise cash in -- I just wrote rapid fire smaller roleplays that were very short, bizarre scenes and tried to keep them really offbeat. I seem to remember getting some inspiration from the Alien movies even though not much of that crossed over into the writing itself.

For Brock Lesnar I just would think of Brock in action and how he'd probably talk if given more air time and had more of a trash talker's personality -- sort of mixing Sid or Mister Mystery trash talk with the type of person Brock seems to be portrayed as on TV, just not giving a shit about anyone and talking down to them like they're worthless.
