Ultraman Wiki

The Ace Blade (エースブレード Ēsu Burēdo) is a weapon made of energy used by Ultraman Ace. Ace summons the blade through use of his Ultra Psychokinesis, and generates it from his own energy.

Ace typically uses this weapon in extreme cases, as shown when he killed Doragory using it, Life of the Sun, Life of Ace and through sheer determination, as seen when he killed Sphinx after the death of the Orion girl Michiru. The Pyramid Is a Terrible-Monster's Nest!

The Ace Blade takes the form of a Katana without a hilt, and Ace typically performs several dramatic techniques with it before using it, such as twirling it around in his hands. Though the blade is extremely sharp and resistant to damage, it is not indestructible, and can break if a strong enough blow is inflicted to it, as demonstrated when Baraba was able to shatter it with his mace. The Last Hero However, its nature as a sword conjured from Ace's own energy means that in effect, it is unable to be truly destroyed.



  • The Ace Blade is one of the few Ultra Weapons to not come from a bracer of any kind, instead it comes from Ace's own power.
  • In the TV series, the Ace Blade is a Katana (刀) but in Ultraman Land stage shows, it took the form of a Bokutō (木刀), a class of sword commonly used for training. The reason for this change is to avoid unlikely accidents or injuring the actors by mistake.
