The Hidden HiveWing of UA/The HiveWing King

Everyone believes Denki Kaminari is a regular human with electrification Quirk, but he's really a HiveWing named Tick and he's the son of Lady Bloodworm, yes that means his aunt is Queen Wasp.
He was always different from the rest of his tribe because he can't be controlled by his aunt's "Hive-Mind" and he's probably the first dragon in his world to get a Quirk. Because of this his mother told him to keep his powers a secret.
But while he was defending his cousin, Wasp's daughter and heir the throne, Pantalus from a pride of lions with his Quirk, he didn't notice one of Wasp's guards was watching. Later that night he told Wasp, she then took over all the HiveWings in Bloodworm Hive.
But Bloodworm asked the SilkWings to make a secret passageway, just in case. Then at the end of the tunnel Bloodworm used a spell from a book of spells (from before the Scorching) she found when she was a dragonet to open a portal to another world. But unfortunately the portal will only stay open long for one to go through.
So, Bloodworm pushed Denki through the portal with the spell book, so he'll be safe and so Wasp can't use the spell book. Ever since leaving his mother Denki never told anyone of his past or who/what he really is, except the people who took care of him, and he wants to keep it that way.
But when Shinso then Kirishima disappears and a month later Kirishima comes back injured and with a few changes, Denki starts having second thoughts about keeping his dragon size secret.
You just have to read to find out.

Kind of both a Lion King and Elena of Avalor AU.
