Check out the Super High-Quality Scans of Kamen Rider Xross Saber, Kamen Rider Crimson Saber & Kamen Rider Featuring Saber.
Though everyone was writing Kamen Rider Saber's Final Form as "Cross Saber" till now. Turns out the official romanization will be "KAMEN RIDER XROSS SABER". The sword will be called "HAOUKEN XROSS SABER".
Kamen Rider Xross Saber's Finisher is called Haou Xross Seiretsuzan. Seiretsuzan means Star Slash.
Some fight pics against Kamen Rider Solomon. By the way, there won't be any new Megid. Charybdis Megid will appear and fight against Xross Saber and Blades Tategami Hyoujuu Senki.
Not many scans for Superhero Senki other than this shot. Looks like everything is in secret.
