Built for [[Robot Wars: The Fifth Wars|Series 5]] and the first series of ''Robot Wars Extreme'', '''Evo IV''' weighed 95kg - 20kg more than Evo III as a result of the increased weight limit introduced for those series. Amongst various changes to Behemoth's armour and drive systems – increasing the robot's all-round durability and giving it a top speed of 7mph – an overhead spiked axe was added on top of the scoop as extra armament. In addition to offering increased damage potential, the axe gave Behemoth the capacity to grab, lift and carry opponents across the arena, as demonstrated in its [[Robot Wars Extreme: Series 1/Challenge Belt|Challenge Belt]] battle against [[Stinger]]. The self-righting arms were initially carried over from Evo III for its appearance in Series 5 - attached to the scoop with wires - but were later replaced with redesigned arms for its Extreme 1 Challenge Belt, Wild Card Warriors and Mayhem battles, all filmed after Series 5. The newer arms had a more angular shape and were connected to the scoop via chains, firing outwards whenever the scoop was raised.

An earlier version of Behemoth Evo IV, which featured no axe weapon and the srimech arms from Evo III, also fought in the Extreme 1 [[Robot Wars Extreme: Series 1/All-Stars|All-Stars]], which was filmed before Series 5 and the rest of Extreme.
