Monster Hunter Rise: Sunbreak | Chapter 13: Malzeno

A dragon covered with elegant silver scales. It uses the Qurio to drain the life energy of other living creatures, creeping around at night and attacking its prey from behind. It appears almost regal to start with, but after draining enough energy it can turn a violent, fresh-blood crimson. This form is known as the Bloodening and is widely feared. David Levy - Erasure
