The story goes that the creator of Kamen Rider took a few production designs of the character for his kid to pick. One design was based on a grasshopper and his son picked that one. Thus, the original Kamen Rider got the grasshopper theme.
We were trying to figure out if bugs have blood this past weekend. Turns out they have hemolyph instead of hemoglobin which is basically goop. So to remind me, I sketched a grasshopper.
