First, Nam kicks the opponent in the air and then he proceeds to punch the opponent into the ground, landing them on their back. Then, Nam jumps up high into the air and makes a cross with his arms, and falls down toward the opponent at full speed. Last, he slams onto the opponent with full strength, inflicting a huge amount of damage.
Nam uses this attack as a final resort in his match against Goku in the 21st World Martial Arts Tournament. After Nam was apparently saved in his match from Goku's Tornado! (because the latter fell on his back due to dizziness), Nam decides to finish the match before he loses somehow. He proceeds to jump 40 feet into the air, and does the Cross Arm Dive's slam on Goku, knocking the young Saiyan unconscious. Nam explained that the Cross Arm Dive knocks the opponent out for about 10 days, so Goku has no hope for winning. As the World Tournament Announcer proceeds to count to 10, Goku's friends were worried that Goku really was unconscious. As the number 9 was counted, Bulma yelled out, "Dinner Time!", immediately waking Goku, much to the shock of Nam, the announcer, and everyone else in the audience.
- Cross Arm Attack - A variation used as by Nam as a Blast 2 attack in Dragon Ball Z: Budokai Tenkaichi 3. In this version Nam charges toward horizontally with his arms crossed and lacks the aerial dive of the original.
