I was tempted to adopt Yelling Bird as part of the crew, but I don't like using characters that belong to other people. "You are foul-mouthed and rude enough as it is."
I use plenty of characters from other sources, but a lot of them are different enough that they aren't really recognizable for who there supposed to be. Grimlock is currently stuck in an human body that looks like Winry Rockbell with an cybernetic leg and arm. Megatron trying to cure Grimlock also ended up a human female. And my Title character Lio is more me in Lio's body. I also have a Timelord character I don't use that much with a android cat girl companion named K-10.
Pretty much. He does come from a different universe and he named himself after the fictional character, although he's crossed into the reality where the character isn't fictional a few times. He's met the Doctor's fourth incarnation once when K-10 was just a cat version of K-9 and once after she got the android body. K-9 was jealous of the upgrade.
The bad guy in Flash Gordon is Ming the Merciless! Does Brian Blessed look like Ming the Merciless to you?
Well? Does he? DOES HE?! "The character is Prince Vultan, leader of the Hawkmen on planet Mongo, and an ally of Flash Gordon."
