In reality, I'd spend a long time trying to come up with something obscure, that would take anyone not me 10 minutes to figure out.
Off the top of my head, though:
The Guile-haired soldier from X-COM
A frigate, or a catapult, or the settler from the original Civ
The starting ship in FTL
Ivan from Jagged Alliance 2
A Knight from Civ 4
I could be talked into some more, like Simon Belmont from Castlevania 1, the thing from Clu Clu Land, something from The Witcher, the Hollow Knight, maybe something from Deus Ex.
Actually, I'd probably pick some random art hanging on the wall of a game. I think Dishonored had some cool shipwreck art. Some game I played recentlyish did.
