It’s worth noting that one: more than half of them died in some kind of “wipeout”, so only Jupiter, Vulcan, Neptune and Mercury survived.
Two: Pluto isn’t here despite being Jupiter and Neptune’s sibling, since the former isn’t part of the Consentes, be it here and in the original Roman mythos.
And lastly: I know that Jupiter and Neptune are siblings, but that won’t stop me from shipping them together, as incest is one of the least surprising parts of mythologies in general. (There’s a lot of it, I’m sorry but it’s just how it is-)
