Syvalion (サイバリオン) is an arcade shooter video game released by Taito in 1988 and designed by Fukio Mitsuji, creator of Bubble Bobble. The player controls a golden metal dragon which flies around, breathing fire at its enemies while collecting power-ups to recharge its fire. The enemies are robots and tanks. At the end of each level, the player fights a boss. It was re-released for the PlayStation 2 as a part of Taito Legends 2 in 2006.
