Dragon Ball's character design philosophy has always emphasized strong family resemblances, and nowhere is this more apparent than in the striking similarities between parents and their children. Akira Toriyama's deliberate design choices create visual storytelling that reinforces family bonds and genetic inheritance within the series.

The parallels between Bulla and Bulma showcase Toriyama's attention to detail in creating believable family lineages. From facial structure to hair design, these similarities aren't coincidental but carefully crafted elements that strengthen the narrative connection between generations. Similarly, Bardock's resemblance to Goku serves as a powerful visual reminder of Saiyan heritage and the cyclical nature of Dragon Ball's storytelling, where past and present generations mirror each other in both appearance and destiny.
