MLP: Thousand Blade Highlander

MLP OC: "Thousand Blade Highlander" Seiren Zero from the fanfic in works "The Last Element"

The pony who acts as an extension of Holy Light's contract, Seiren Zero, more known as the Legendary Thousand Blade Highlander, is the hardware of their combination.

His life was spared and transformed after Holy Light begged the Spirit Lady of the Light to save him after he had gone to far ends to save her. He became a Highlander but without a weapon nor having thought of one during his transformation, both of them were under fire again.

Attempting to hide out in a building nearby, Seiren worked to find something to defend themselves with and soon came across a blade hooked to several ancient looking devices. He took it and it quickly activated. A similar reaction took place as the book Holy Light carried also activated and tried to respond to Seiren Zero's activation. The overwhelming power nearly drove him insane until Holy Light used her new found abilities as an Ascendant to merge with him and take control over the book, calming both Seiren and the artifacts. This combination was complimentary and they soon found themselves wielding one of the few remnants from Solunarian technology as the Eclipse Duo.

Where Holy Light can be a bit of an innocent airhead, Seiren is a passive nice guy who looks out for her and loves to see her smile. He loves to travel and is initially the first to be able to communicate with Holy Light telepathically. However, when danger strikes, he will quickly switch to a defensive stance, bringing out The Thousand Blade Divider. Due to the strange mechanics of both his device and his combination, he's one of the few Highlanders capable of fighting in the air.
