Kind of my own ideas more so. Just random E-Series robots, just to see what I could do design wise.
The "Egg Rodent" has a funny story attached to it. Back during Archie's early run with Sonic X, a lot of the artwork was.... meeeeeeeeeh...... I hated how generic all the E-Series robots looked in the first issues, and I had attempted making my own versions to try to improve upon what was given. I kind of re-explored it again through this. I'm happy with it, but I still seem to infuse Beast Wars Rattrap into it, lol.
