In general, there are two types of Abyssal ships

humanoid and non-humanoid.

Humanoid

Non-humanoid

Compared to non-humanoid types, humanoid Abyssal ships have

more superior firepower, armor, intelligence, and mobility.

They also develop their tactics in a coordinated manner.

They’re more than twice as powerful as non-humanoid Abyssal ships.

Especially the heavy cruiser class and above

even with the same class, it's pretty difficult to go one-on-one against them.
