The Chitauri Blowtorch is a weapon designed by Tinkerer by manipulating salvaged Chitauri technology with human mechanical engineering. Powered by a Chitauri Energy Core and capable of slicing through steel and concrete, the item was sold to several parties on the black market.
A Chitauri Blowtorch was purchased by a quartet of criminals, who used it to cut open numerous ATMs at the Queens Community Bank in order to acquire the money. Their attempt was interrupted by Spider-Man, causing a fight to break out and one of the robbers, in a last ditch effort, increased the power of the weapon to kill the young vigilante, only to lose control of the weapon and destroyed the bank and Delmar's Deli-Grocery, a bodega across the street, forcing Spider-Man to save his friend Delmar, thus allowing the robbers to escape.
The Chitauri Blowtorch acts like a industrial blowtorch, only powered by a Chitauri Energy Core, allowing it to cut through almost any material, shown being able to destroy a building on maximum power.
