>>99691509you fool, practicality has no place in SCIENCE!!!*, everyone knows Style/Aesthetics is the most important aspect of that field, you're probably the kind of person who thinks that a Walking Eye or a Giant Robot are impractical
also the guy who drew that pic(and
>>99640372 &
>>99640839) mentioned that rather than the usual Rule 63 scenarios of either being Dexter born as a girl or turned into one, he envisioned this version of Dextra as being a genetically modified clone of Dexter created to be a lab assistant^, so besides the fact that she's hypothetically replaceable, it's also quite likely she's been modified to be more durable and/or with enhanced healing
*which is a completely different thing from regular science
^which is actually a concept I like quite a bit, genderbent clones are surprisingly rare all things considered(like X-23 and Ultimate Spider-Woman are the only other examples I can think of at the moment)
