General Notes

The XCD-001-1 Prometheus gave Sekaino Megami a war machine capable of achieving her genocidal goals. All she lacked was a pilot with the skill and resolve to unlock its full potential. 

Megami always intended ZoDiaC operative Sieg Friedlander to be her lead XSeed pilot. But as always, she hedged her bets by simultaneously grooming her maniacal hatchet man Eiyu Masz for the role. To that end, she green lighted Masz's custom YCR-015-1 as a training unit to prepare him for the brutally high-performance XSeed.

When the first Zwei Dolph Custom proved itself beyond even Megami's expectations, she secretly ordered Seed Corp to produce a second unit, ostensibly as a backup. The second custom Zwei Dolph was painted blood red to distinguish it from Masz's midnight blue original and shipped to the Kazoku's Metis asteroid base. There, CF tech crews nicknamed it the Roter Stier or Red Bull.

The destruction of Metis at the end of the Kazoku War left no records as to whether or not Sieg ever piloted the YCR-015-2. If he did take the powerful machine's stick, his operating time was most likely limited to a test flight or two, since he fell ill shortly after arriving at Metis. The Roter Stier was almost certainly destroyed along with all the other materiel and personnel that perished when the asteroid exploded. But its striking red paint scheme carried on to grace the XCD-001-2 Kreuzgun.
Brutal mecha action!


  1. I love the official agnosticism about the amount of piloting and fate of the machine.

    For the rest, I hold that a Jayne's-style mech data sheet compilation should be created, once all of the mecha for the series have been designed.

    1. Thanks for the valuable feedback!

      A fact sheet like Jane's? Excellent idea! With a line illustration.
