BEHOLD AND COWER IN FEAR, MORTALS! IT IS NEPTAR THE (MODERATELY) WRATHFUL! he lives on Jupiter and enjoys destroying all life, if he feels like it. he destroys all death, too. not many people can do that, you know. HE IS NOT UPSIDE-DOWN. THAT IS JUST HOW HE NORMALLY LOOKS. DO NOT MOCK NEPTAR! GRRRAGH! YOUR DEATH IS IMMINENT! (probably)
PS: this picture is to scale. that is NEPTAR's actual size relative to Jupiter.
