"The Yellowjacket is an all-purpose weapon of war capable of altering the size of the wearer for the ultimate combat advantage!"
Darren Cross[src]

The Yellowjacket Suit was a powered suit created by Darren Cross as a weaponized version of the Ant-Man Suit, made of military-grade Kevlar fabric and titanium limbs, in order to maximize the military applications of his version of Hank Pym's Pym Particles.

The Yellowjacket Suit was created by Cross Technologies, with Darren Cross who used the Ant-Man Suit technology as a base. The partly mechanized suit was designed to be weaponized and more advanced version of Hank Pym's suit. The mechanisms in some of the metallic parts of the suit may possibly be used for resilience or strength enhancement. It was designed with mechanical appendages on its back with the pair above the other being able to fire beams of energy and to fly as well.

Darren Cross using the Yellowjacket suit

Cross intended to make a sale and demonstrate the capabilities of one of these suits to potential buyers, before the demonstration was sabotaged by Ant-Man. Cross would later put on the suit in order to deal with Ant-Man. After a long and difficult fight, the suit was sabotaged by Lang, who shrunk between the molecules of the solid titanium armor to reach and destroy the suit's circuitry and inner mechanisms. The suit's now unstable shrinking function caused Cross to be crushed in the suit, imploding his body into nothingness, destroying his suit.[1]

"The Yellowjacket can manage any conflict on the geo-political landscape, completely unseen. Efficient in both preventative measures and tactical assault. Practical applications include surveillance, industrial sabotage, and the elimination of obstructions on the road to peace. A single Yellowjacket offers the user unlimited influence to carry out protective actions."

  • Size Alteration: Using the original Ant-Man Suit and Pym Particles formula as a start up point, Darren Cross developed a new suit which allows him to reduce approximately to the size of an ant whilst gaining enhanced physical capabilities.
  • Superhuman Strength: The suit grants the wearer superhuman strength whilst shrunk. This is thought to be due to the Pym Particles enhancing density and compressing energy and physical force to the user, giving them the power of a bullet. In the case of the Yellowjacket, its mechanisms may be able to enhance physical strength and resilience of its user even in normal size as he was almost able to crush Ant-Man between his hands while Lang was in shrunken form. Though, Ant-Man in normal size was able to take on Cross while the latter was in the Yellowjacket. In addition, due to its titanium composition, the suit's mechanized stingers can be used as melee weapons, while Cross used to knock Jim Paxton's gun out of his hand and to help him grab Lang into order to hurl him through the air.
  • Superhuman Durability: To be added
  • Flight: The suit has the power of flight. The backpack housing the two top 'antennae' on the suit's back has exterior booster rockets at the bottom of the tentacles that give the user levitation capability and forward propulsion.

  • Energy Pulse Stingers: The bottom pair of the four mechanical titanium limbs on the suit's back form shoulder-positioned directed-energy weapons. The energy beams are blue and laser like, burning through most substances and, even when the user has shrunk, can easily kill human targets, much like bullets. When in normal size, the larger beams can easily burn through and destroy objects as large and as thick as a wall.
