Before moving in with his aunts Spiracle & Burning Love, Hindwing had a more direct family; that being of his father Hexapoda, his sister Antennae, & his sibling Silkworm. All three of which were notable members of the Ace Of Swords.

  Changeling families, on a structural level, are similar to ponies’; except biologically, all changelings are asexually produced children of the current or previous hive monarch (in this family's cases; they're all the direct children of the former Queen Chrysalis). Family structures form as different larvae are assigned to different broods- Hexapoda is considered Hindwing, Silkworm, & Antennae’s 'father' as he’s the one who was assigned to raise & take care of them, while Hexapoda is Spiracle’s 'cousin' because their respective parents were siblings in the same brood, & so on.

  Hexapoda, Antennae, & Silkworm have been missing & considered legally dead for nine years. Unbeknownst to all, they've been turned into statues by Platinum Touch. Hindwing misses them dearly.
