Actually, there’s a reason for this. The human brain interprets round shapes as friendly, and the color yellow is associated with happiness and energy. So this design basically reads, “I’m a happy friend!” Its basically the most non threatening design you can have, which makes sense, even for Krillin and Saitama.
there’s not enough round or yellow in this world to convey eddie as non threatening
