Thanks to Saito-san on DeviantArt, we now have official artwork of Teen Zap. Now, the only one of the brothers whose design I'm still iffy about is Electric.

It is a huge jump from his previous design, I know. Technically speaking though, the only serious change is the new hair, (and the sharper quills,) which could just be explained as him growing hair over time. (probably hit puberty.) I love how he still has that innocent baby face though; it just tells you that underneath that hair is still the same shy but sweet Zap.
