In my adventures in No Man’s Sky I’ve seen a variety of alien creatures.  None yet have really made me go “Wow!” as much as several of the creatures on what I named “BF Togte II” (the system is named “BF Togte I”, the “I” being a mistake because I thought I was naming the first planet I landed on in the system, and “Togte” meaning “This One Goes To Eleven”).
