Sians are a Alien species I came up with that are tall like Creatures that have a cyclops eye and have a certain behavioural Pattern, If you want to see the behavioural pattern their will be a chapter for that also with the looks of my two ocs.

Male sians are very tall some would have trouble with the human houses on Earth since the houses are small and Male sians are big both in size and wide

Female sians are literally like the same size of male sians but only slightly smaller then males, their are some females that are smaller like my ocs friends. My ocs female sian friend is smaller then my human oc and my ocs Male sian is not that taller then my oc and her female sian friend they had said to her once it was a birth defect but later found out they were just slower then others and that the process was going to happen but was just taking its time it might also have been impacted by my ocs Sudden interest in them and their interest to my oc human

My Oc's Mates Size:
Lets just say that my human OC's Mate is is extremely tall for a normal male sian he is regarded to be part of a family that is both powerful in Genes and looks amongst other things

I'll add more if it changes 💖👏👌😎
