Dora Knight

Dora Knight (ドーラナイト, Dōra Naito) (15): An expert swordsman who used Durandal, an evil sword which Bandora had a 10-year old boy, Shigeru, make at midnight. This made Dora Knight invincible as Durandal made any other weapon it clashes with rusty. The only thing Durandal was unable to do was to kill it's creator, Shigeru. Once Shigeru was in Daizyujin, Dora Knight was powerless as he is killed by Daizyujin.
