As one of TBI's ocs, you constantly evolve.
Let's start with Lemony, who I first though up at around 15 years old I guess.She was a talking sparklecat with a Jamaican accent.
She then evolved into a tomboyish sparkleanthro with massive tits and hips.
Then she got an underwater edit dubbed "Sublemony" because I came up with Lybbi and Lybbi needed a friend.
All of these designs are terrible hhuhhhghghhhhhgh I was a troubled child
Then I joined a TF2 rp group like a two years ago and she turned into a non-furry Jamaican Engie who constructed a BigDog and rode it everywhere because I've always been obsessed with BigDogs
Another good example of my characters dramatically evolving (appearance wise, at least) is Cypress.She started out as a playful human female who was somewhere between 19 and 23. She had a robot sidekick who was mainly there as a father figure.
Her palette didn't suit me so I turned her blue and gave her tentacle hair. She, at this point, was obviously no longer 100% human so I decided that she was some manner of alien.
Targos got a bit of an upgrade as well because he reminded me of "some mutant offspring of Briareos".
Then I have the character who has evolved the least, but been tortured the most.
Presenting, drumroll please....
Chris!He started out and ended as a Pyro in the same group as Lemony. (I never really used Lemony...)
he stared out straight and turned into he most massive faggot you have ever seen. He also did a bit of "crossfactioning" with a black pyro hooHOO so that was a trip.
I don't have any good not gay pictures of him but he's had ferrets in his pants and he's been manhandled in prison and he's been drawn as a centaur and he had an altogether horrible life. The end
No wait scratch that here he is as a Tron
oh and catfighting a spy
Chris was my favorite.
