Great GoBuster, finisher Demolition Thrust
Escape is Enter's replacement
Ene-tan! I like his cockpit... cute frog leg handles. Ene-tan is voiced by a woman, leading Morphin Grid Wikia to think Ene-tan is female, but I don't know yet. Bomper and Triptor were both voiced by females but were male characters.
FS-0O Frog. My guess would be that Yellow Buster drives him (or her) but the movie mecha are usually piloted by Red (GaoKong, SamuraiOh, Kyoryumaru, etc.)
