We've seen a bit more of Liger The Arthur! Aside from appearing in the BCH commercial (below), we also saw an article from CoroCoro, which showed a profile image and one of the new images from CoroCoro Comic. We're still waiting to hear more about the application process.

 Interestingly, we received a couple of concept sketches from Moritya, the designer of the Arthur and the manga artist for Zoids Wild and Zoids Wild 2. He showed us 2 different concepts for potential ligers. Liger The Arthur was shown with a giant metallic silver lance ((Purification??) Gungnir), and matt dark blue armor. The second concept, Galaxy Liger, showed a Light Saber type Beam Sword, metallic silver equipment, clear light blue armor, red clear visor, and white matt secondary armor.
