There are 8 different Nether types:

The lost or wanderers are the weakest nether and the earliest form of nether and still retain a bit of humanity.

2. Crawler

The most common nether they are small and crawl on the ground and can be found in buildings or open areas.

8. Reaper

By far the most formidable and dangerous nether there is, they mainly appear in reaper surge but in extremely rare cases be found in the wild by itself. When facing them it is highly recommended that you bring at least 3 allies, they can be taken out single hadedly with a good gun and high skill points though, but it is unlikely.

Attack: Once they spot you they will charge with great speed and when they catch you they will hack and slash with their arm blades, killing you quickly. When in combat against them it is vital to keep on shoooting them and reload as quick as possible while keeping your distance or you could wait until they are distracted by your allies giving you a chance to shoot it. It is unwise to run away because they can easily teleport anywhere or run after you, a melee weapon is out of the question.

Appearance: Quite tall and dark, they have distinctive blades as arms and red eyes. They also have 2 small arms at the back of their neck that do not serve any purpose, same as the Hunter.
