☾ : Sleep headcanon: he sleeps shirtless and stays up until like the troll equivalent of 4 am reading, brooding and plotting his genocide plans. his eyes always have bags and something he does a lot is fall asleep anywhere in his hive because he tends to collapse of exhaustion.
☠ : Drinking/drunk headcanon: he’s one of these angry drunk types. the ones that will pick a fight without hesitation when intoxicated.
☼ : Childhood headcanon: i’ve got the typical childhood eridan headcanon where he believes in magic and pretends to be a wizard.
☯ : Genderbent headcanon: i drew a genderbent eridan at one point and that’s basically how it would look for me.
⋆ : Sex headcanon: i tend not to think about these, hm! i suppose i see his favourite position as being missionary, and he’s a big hugger and kisser etc.
♤ : Cooking headcanon: eridan is one of these guys whose cooking limits end at ramen and sandwiches.
☻ : Mood headcanon: mood headcanon? grumpy like 24/7 mostly because of how little sleep he gets and how much pressure he puts on himself.
