Here are some designs done to give the storyboard artists something to work from. I always enjoyed adding some color, but it was never really followed. These are all pencil and marker on animation paper. The design for Technus 3.0 made it all the way through the board pitch for the episode, "Identity Crisis" but then it was realized that the design didn't work for what needed to happen in the story. Whoops, should have read the script I guess.
