Skeletal Dragon

Skeletal Dragon (スケリトル・ドラゴン) is a powerful undead being that mimics the shape of a dragon and is capable of destroying a city.

Appearance
The Skeletal Dragon is composed of countless human bones with an overall height up to three meters tall. Formed from bones with a rib cage devoid of organs nor flesh, it appears light despite its large frame. Its head contains four hollow eye sockets, each with a crimson glow. The jaw of the skull is lined with sharp teeth along with a pair of bat-like wings attached to its shoulders and four limbs.

Abilities
Aside from its massive strength, the Skeletal Dragon's specialty relies on its ability to nullify magic that ranges up to 6th-tier. Therefore, this dragon's ability makes it the worst opponent for some magic casters. In particular, the low-level magic casters who used spells lower than the seventh tier are the ones helpless against it.
