This papercraft is V-Siren 103 Neptune, the personal mortar headd of the Lader branch of the imperial family, based on the manga / film / game series Five Star Stories, the papercraft was designed by Bartman.
Originally piloted by Lader VIII, it was later redesigned and upgraded by King Lader and a collection of the galaxy’s finest meights (this is where its output gets the upgrade from 1.4 trillion horsepower to 1.5 trillion). During its redesign phase, the Siren moved on its own to protect Christine V, daughter of legendary Kneu Syltiss knight Barbeleus V, from capture. Witnessing this, the emperor decided to award the Neptune to Christine upon the day of his retirement, and with it came the title of "Highlander", which belongs to the Fillmore Empire’s finest knight.
The Neptune’s main weapon is a large speid, equivalent to a Claymore for a mortar headd. With the Neptune’s advanced, power-assisted muscle it is capable of causing massive devastation with this blade. It also carries a smaller speid hidden in its veil which it can deploy simultaneously while using the veil for defense. The article Internal Structure of Mortar Headd shows the Neptune’s internals.
