獅子の勇者は収納式で、翼の勇者は装着式。そのため翼の方は獅子に比べると少し小柄 #異世界勇者ロボ

The Leonine Hero is a retractable-type, while the Winged Hero is a put-on fit type. That's why the Winged one is a little smaller compared to the Leonine. #IsekaiYuushaRobo

XE-Leon, the Guardian Beast of the Earth; and XE-Garuda, the Guardian Bird of the Sky. Plus one more. Probably. #IsekaiYuushaRobo
