With my writing, I use my own characters (I leave originality alone when I can..) and my own plots with a general theme to what I extract ideas from. So in other words, Gundam IS NOT MINE, Gundam design IS NOT MINE, and the characters in my stories ARE MINE or my friends. Of course Gundam isn't all I write..Ack, no..It just happens to be what I have a lot of..But I write a lot more than that now!
The only exception to this is the poetry I write. These are usually random but are based on my own feelings and include people from my life, but so I nor them are questioned about my writing (in truth), I do not disclose names, nor do I change them. I work around the 'pointing fingers and naming names' aspect for everyones' sake.
One last thing. I have multiple dimensions of a single character..For example, one of my newly restored characters, Alia. No one knows much about her except in one dimension. I have maybe..4 different stories with the same character, but they aren't sequentual. They're pretty random. But they're suppose to be like that. I RPG with multiple people at different times. ^^..
As a final note.. ^.^ Death to Scooby Doo!
