This split image pretty much speaks for itself, and the characters do seem to share a rather distinctive head shape/profile, but did the design team behind Prometheus really draw inspiration from this obscure character featured on SpongeBob SquarePants?
There's no way to know for sure, but it's fun to think that the concept artists were hanging out watching Nickelodeon when they found a character design that struck their fancy.
And we all know that SpongeBob is the cornerstone of creative character design, right? *wink*
