Battle Tutle Bros.

Battle Tutle Bros. (バトルタトルＢＲＯＳ) is a pair of turtle enemies from Mega Man Zero. The smaller turtle shoots projectiles in an arch, and the larger one shoots missiles. The former can be easily destroyed, while the latter can be invulnerable to most attacks when its head is withdrawn into the shell. They appear in the Secret Base (during the Find Hidden Base mission), in Neo Arcadia Shrine, and Neo Arcadia Core.

Trivia

 * The word "tutle" (タトル) comes from turtle (タートル).
