Bigwings are the eldest, usually the largest, and occasionally the strongest dragonet in a MudWing clutch of eggs. They are the first to hatch, and they help their younger siblings hatch by cracking open their siblings' eggshells from the outside. When grown, they become the leader of the sibling group called a troop, and are basically the ones who are responsible for everything.
If a group of siblings loses its bigwings or several other members of its group, the clutch will form a new group with another MudWing clutch, also known as unsib. They look out for their clutch at all times, even though they are not officially blood-related, they will lead them.
Queen Moorhen is the bigwings of her sibling group, and has at least four siblings.
- When Clay was hatched, his bigwings instincts told him to help the other eggs to hatch, but was mistaken by the dragonets' guardians as attacking them. He thinks he is a monster for the majority of The Dragonet Prophecy before discovering he was actually trying to help them hatch.

- A MudWing queen, the Bigwings, has never been killed by her siblings.
