Battle of the Mutara Nebula

The Battle of the Mutara Nebula was the final engagement between James T. Kirk and Khan Noonien Singh, inside the Mutara Nebula, in 2285.

At the conclusion of the battle, Khan's USS Reliant (NCC-1864) was defeated by Kirk's USS Enterprise (NCC-1701). However, Khan was able to detonate the Genesis device in a last attempt to kill Kirk and destroy the Enterprise. Fortunately, the Enterprise was able to escape thanks to the sacrifice of Captain Spock.
