"Apollo-G"

I had an idea for the name of a character once. His name was Apollo-G.

Apparently, his parents had had an abortion for their first "child," and, feeling consumed by guilt, named their second child (a son) Apollo-G. G is the seventh letter in the alphabet. Apollo 7 was the first manned Apollo mission after the disastrous Apollo 1 mission (which lost 3 crew members). Apollo 7 was therefore a confidence building mission for NASA.

This character, Apollo-G, by extension, lives a life that is always in reference to a sibling that never was. He is literally an "apology" for the abortion committed by his parents...
