>>5954000Yes, it's an actual thing in Dragon Ball. Goku in the manga was way shorter than the anime made him in the 23rd World Martial Arts tournament. He was more 4'6 rather than his more saiyan saga cemented height 5'7 statue (anime 23rd WMT+) and became full 5'9 by the Android Saga. Vegeta is Way shorter in the saiyan saga than how future arcs depict him. By late Android to Buu Arc Vegeta got a real glow up in height compared to the troll doll stature he championed. Even Super tries to make him look consistently taller than Bulma. This is ironic since Krillin got made to look shorter despite being not THAT short since the saiyan saga.
So yeah, 18th birthday Koku is gonna be hitting the six-foot range, mid-to-late adult Koku I'm still thinking but somewhere between Wonder Woman (6'4) and She-hulk (6'9 for the sweet spot. Might change it.
