Combat strength level

Jack has excellent fighting ability. With close combat skills such as punches, kicks, and throws, he can usually corner or even suppress enemies. He can still survive at full strength. Killed enemies directly several times.

Especially for kicking skills, Jack once worked hard to master the meteor flying kick. He was the first Ultra warrior to increase his combat power through hard training after failure. In addition, Jack is also good at aerial combat and possesses skills such as aerial maneuvers; however, water combat is Jack's weakness and he cannot give full play to his fighting abilities.

In terms of light skills, Jack has most of the same special moves as the first generation (Spacium Ray, Eight-Point Light Wheel, etc.), but he also has his own unique skills that can be used effectively according to the needs of the battle situation. Jack also possesses many powerful superpowers, such as the telepathy barrier that pushes back the tsunami (Episode 13).
