Famous Battle: Hulk vs Leader

Battle Fought: Hulk #400, 1992
Over the years, the Hulk's greatest nemesis had proven to be the nefarious Leader!, So when the opportunity arose to carry his grudge back to the Leader's home base, the now intelligent Hulk did just that! Arriving at the Leader's arctic survuvalist colony in time to witness a battle between his gamma-spawned foe and the hordes of Hydra, the Hulk joined in, mercilessly ravaging both sides. But in the heat of battle, the Hulk caused the Leader's death - a tragic result of the Hulk's loss of control of the savage that seethes within him.
