Math is fun

Ah, I remember this bit of blursed knowledge.

5’5” and 123 with Vegeta’s mass and seemingly low body fat would seem exceedingly low weight when we consider that MMA fighters average height for feather/bantam weight is 5’6” and you have 5’5” middle weights coming in at 97k (about 215lbs) who are nowhere near as huge in muscle mass as Vegeta. That said- we also have to factor in that Vegeta isn’t human. I’m not an expert on Saiyan anatomy so I can’t say how biologically similar to humans they are. They have blood and need need food and water- their requirements for nutrition and rest and oxygen as while as various other aspects of their biological responses and needs differ some from what we’d expect or consider possible in humans- so it is possible Saiyans have a different cellular or even molecular structure etc. Of course the franchise is generally not known for its extreme realism or coherent world building so since physics barely applies and applies, and applies selectively- it probably doesn’t matter what anyone weighs.
