Tonbos are Galaga dragonflies. They only appears in some challenging stages. However, they don't attack. Tonbos appear in waves and they commonly attack in Galaga Arrangement, Space Galaga, Galaga Wars, and Galaga Revenge. In Galaga Arrangement, much like the Goei, there are some Tonbos that are recolored green (instead of blue in some stages especially in the final stage while defeating King Galaspark).
