Pavel Chekov is security chief and tactical officer on the Enterprise. He also sometimes substitutes for Spock as science officer. Chekov is a good friend of Sulu, and the two often crack jokes aboard the ship during 'down times.' Chekov was born in Russia and is very proud of his heritage; he often makes references to his homeland. The character is also admired for his Monkees-inspired bowl haircut, and his surname is thought to be a nod to the famous Russian novelist, Anton Chekhov.
