Grunty once protected Azeroth from interstellar invasion by occasionally firing his gauss rifle into the air to make sure no invisible spacecraft are swooping in to attack. All that changed one Tuesday night when he took part in a 25 man raid. Sucked into a magical vortex and transported across dimensions, Grunty wound up in the Koprulu Sector. There, he often took shelter among the zerg, as murlocs are the only creatures the Swarm has refused to infest.
During the Failoc-alypse, he helped a number of heroes (including Jim Raynor) by dropping nukes on the invading failocs at a cost of 250 gold pieces. Grunty was not harmed by any of the attacks and always teleported out afterward.
Heroes of the StormEdit
Grunty was set to appear in early builds of Heroes of the Storm. He was good at supporting heroes, was the fastest hero in the game and benefited from dexterity items, but was easily killed. He was classed as an agility, carry-type hero.
He was similar to a stealth assassin from DotA with a ranged attack rather than cloaking.
He later became a skin for Murky.
