so i did the math, and in the non transformed form of vaccine man, he should be around 467.36cm (or 184 in[~15 feet]) feet tall — in his transformed state he would be around 1216.66 cm (479 in[~40 feet]) tall — this is based on him having the same body part to height ratios as normal humans
(looking back on it, i got the transformed part wrong - he should probably be like 50-60ft tall)
@voliol wow you are very well versed/cultured 👍 (also the japanese name for this is wanpanman so... yeah... i think you might be right 😉)
