Trivia

 * Vay Hek was the toughest Grineer boss before Update 6, which introduced Lieutenant Lech Kril.
 * Vay Hek was targeted for assassination by Lotus as he is a corrupt diplomat who has assassinated multiple political opponents and is a hindrance to the stability of the system.
 * His shotgun is, fittingly, the Hek.
 * He is also one of the more humorous bosses in the game, with taunts such as "Grineer foreign policy starts and ends at the tips of my plasma grenade!" and "Can't we all just get along? Come give your Uncle Hek a hug!".
 * It seems that while Vay Hek's armor color was changed, his decoys were not updated, meaning that his decoys are now yellow while he himself is dark gray, making the decoys even easier to identify.
