Like its name implies, the Giant Mosquito is a giant invertebrate that drinks blood from magical creatures. It looks just like a mosquito, but is much larger in size, about the same as a Dragon. It has four legs, two wings, two bulging eyes and a long dart (or mouth) that sucks blood.
- Jake defeated the Giant Mosquito in its astral form by using a giant fly swatter;
- Large mosquitoes are called crane flies.
