Strong Type is Ultraman Dyna's strength form, though he does not prefer it as much as his Miracle Type. This form lacks energy abilities besides his barrier and the Gulnate Bomber, instead focusing almost entirely on martial arts and strength. First appears in episode 4.

Gulnate Bomber Shooting Version is Dyna unleashes a large burst of energy from his arm. This attack will rip straight through an opponent’s body, often leaving perfect holes through whatever part is hit. Alternatively, Dyna can create a spherical barrier that can absorb enemies' fireballs, which in turn he hurls it back at them.
