Clockwerk

Rattletrap the Clockwerk is a melee strength hero renowned as one of the most well-rounded initiator-gankers in the game. His wide array of disables allows Rattletrap to cause chaos among the enemy and break up their formation, giving his team a powerful advantage in any fight. Battery Assault allows Clockwerk to inflict repeated damage ticks and mini-stuns on nearby enemies, allowing him to constantly hinder any enemies he manages to get close to and single out. He can also disrupt enemy movement and pen in foes with his Power Cogs, which induces an electric shock to foes outside, stunning them while damaging them and burning their mana, and can render enemies caught inside helpless. His damage nuke, Rocket Flare, gives him global nuking power that also provides scouting vision for him and his team. Finally, his ultimate, Hookshot, allows Rattletrap to instantaneously stun a foe at long range and quickly close the gap between them, making him a very strong ganker. Few can escape Clockwerk once he has his sights locked in, and his machinations make him a powerful ally to have on any team.
