You already have a bunch of suggestions, here are a few more of my favorite sci-fi names/characters that I didn’t see…
Hari / Salvor (both from Asimov’s Foundation series) Rico (from Heinlein’s Starship Troopers) Leto / Duncan (both from Herbert’s Dune) Ender (from Card’s Ender’s Game series) Filip (from Corey’s The Expanse series)
