Big Pets

Big Pets (ビッグペッツ) is an amusement park guide robot that was stolen and modified for combat by Dr. Wily, appearing as the boss of Wily Stage 1 from Mega Man 5. It shoots enemies from its head in varying patterns, and if a section of its body is shot, it launches toward Mega Man. Its eyes are the weak spot, and Crystal Eye is the best weapon to use, as well as a charged Mega Buster shots. Big Pets can only be harmed while its eyes are open. The Bit Pets' ability to fly renders the Charge Kick useless against him.

Other media
Big Pets appears in the Rockman 5 manga and has a cameo appearance in Mega Man Megamix.
