I didn’t want to triple post so I edited the above one to make room.
I don’t know why but in most franchises I am a fan of I zero in on the character(s) people care least about and at least semi obsess over them. In Dragon Ball’s case that is Chiaotzu. And Tien by default, mostly because they seem like a package deal.
Trying to figure out what older Chiaotzu’s height might be at around a physical 15/16. He is still a shorty but I imagine his full height is still taller than Krillin. Granted Krillin has shrunken as the years go by which is weird and should be reversed. Dude should not be the same height as his toddler daughter.
But anyway Chiaotzu at perhaps 15, being a cool vampire/jiangshi kid and maybe going to school, getting smart to strengthen his psychic abilities, and being a badass battle partner with Tien.
