Their weapons include Clover King's Club Megaton; Big One's Big Baton; Spade Ace's Spade Arts Power Bow; Diamond Jack's Dia Sword, Dia Laser and Eleki Cutter; and Heart Queen's Heart Cute.
All four defeat Machine Monsters by surrounding them, injecting their four energies into it, kicking it away, and firing their energies at it to cause it to explode. This is the JAKQ Covack technique.

Big Bomber Big Bomber
Introduced after Big One joined the team, this finishing attack consists of a cannon, with the four J.A.K.Q. members bringing out the parts (Diamond Jack and Clover King with the wheels, Heart Queen with the "V" symbol, and Spade Ace with the main cannon) and assembling them before Big One loads it with a missile. In the same fashion as the Goranger Hurricane, the missile fired by the Big Bomber would transform into an object that is usually an anathema to the monster's personality. Either way, the object explodes with the monster caught in the explosion.
