Alkyls
Your High School Bully (affectionate). Usually comes with gender issues and an intent to inflict them on others. Naming is based on the original Esther, because an alkyl replacing a hydroxyl in an acid is an ester. Which also implies that a hydroxyl is pre-transition alkyl. Theoretical template for now.
Esther Lark (kudzu-kintsugi)
Paramin (hanchoh)
This Alkyl is a Dream (of DreamSMP fame). Paramin is short for para-aminobenzoic acid, a metabolite of esters that are used for anesthesia. Notably, she's not DreamXD who presumably is Cain, short for Tetracaine (a more potent Ester than Novocaine/Procaine which you may know from dental surgery).
