This papercraft is Boush the Tinker, a ranged intelligence Hero who relies heavily on his assortment of nukes for ganking and pushing, based on the DotA 2 multiplayer online battle video game, the paper model was created by Israel Flores, shared by Kang Papercraft.
While he does have rather low stat gain, he is able to reset the cooldown on his abilities, which in conjunction with Boots of Travel gives Tinker global mobility rivaled only by Nature's Prophet, which combined with his two high damage nukes, Laser & Heat-Seeking Missile make him a constant threat.
Tinker abilities' mana costs are very high, however thanks to his ultimate Rearm, and Boots of Travel, Tinker can simply to go back to base to refill health and mana, Rearm and go back to the lane to push or gank once more. Acquiring said boots early with a level advantage is key to success, considering he is lackluster without them. With the right item, mana management, and ability management, there is little that stands in the way of this hero. [Source: GamePedia]
