Deadblow was a middleweight robot built by MythBuster Grant Imahara for BattleBots. It was originally intended to be taller and larger with an 8 pound sledgehammer for a weapon before being revised to a silver box-shaped robot armed with a CO2-powered pickaxe (which later had a lifter attachment) and side skirts which were added for Season 3.0 after Deadblow lost to Bad Attitude the previous season. Deadblow participated in every season of BattleBots in which its weight class was represented, and did particularly well (Becoming the Season 1.0 runner-up) until Season 4.0. Deadblow had a severe weakness to wedged robots, losing to a wedge in three of the six seasons it competed (Though there were attempts to remedy it with the addition of side skirts for Season 3.0 and 4.0 and a front wedge for Season 5.0).
Grant sadly died from a brain aneurysm on July 13, 2020. He was 49.

Appearances in Mythbusters
Since Grant joining MythBusters in 2005 (alongside Blendo creator Jamie Hyneman and electronics/control wirer Adam Savage), Deadblow has been used on the show several times - though often with other attachments besides its original titanium hammer. Its debut came in "Bottle Rocket Blast-Off", when Grant demonstrated it - while its accomplishments were reeled off with accompanying footage - before using the pneumatic system that normally powered the hammer to test the pressure rating of a soda bottle. Its most notable use so far came in 2009 in "Driving In The Dark", which saw Grant, Tory Belleci and Jessi Combs testing the myth that smugglers can beat checkpoints at the Canadian border by turning off their wikipedia:headlights while not crashing or navigating wrongly due to lack of light. To simulate an oncoming car with its headlights ablaze, Grant fastened halogen lamps to Deadblow - which earned it the nickname of "Blinky" - and drove it towards Tory, who was playing the role of a smuggler in a go-kart with its headlights off, causing him to veer and crash into the tire wall.
Its other uses on the show include the "Beat the Guard Dog" myth where it played the part of a robotically controlled cat - all that Grant had to do was modify it to mount a taxidermied cat and make the cat's joints hang loosely.
