- Why is Wrath so human? 5 answers
According to the FMA:B series, the homunculi aren't supposed to grow old. Moreover, all of the homunculi other than Wrath (King Bradley) could regenerate themselves. This even includes Greed, who's also a human-based homunculus. We also see in the series that during Bradley's death, his body degenerated. If he was able to grow normally then there shouldn't be such things happening to his body.
