Nightwing

Nightwing is the boss faced at the end of the Batman: Arkham Knight DLC campaign the Harley Quinn Story Pack.

Description
Nightwing has the agility, animations, and moveset of a Combat Expert, the electric sting of a Stun-Stick Wielder in his attacks, and the long durable health bar of a typical boss. The best method is to avoid his attacks, flip over him, and attack him from the back until his health is eventually drained, and be prepared for his occasional ninja-like attacks. Conventional counters are ineffective, so when he's about to strike, flip over him. Takedowns take down a quarter of his health. A horde of infinitely respawning cops, those that function identically to thugs, also back Nightwing up until he is beaten.
