Bunby Heli (ブンビーヘリ,Bunbī Heri?), localized as Blader in some English sources, is a flying reconnaissance robot equipped with video eyes. The Bunby Helis that appear in the games were modified for combat, and will follow and fly into their targets repeatedly. In the first Mega Man game, they come in green and blue; and in some games red.
Bunby Tank (ブンビータンク,Bunbī Tanku?) is a Bunby in Mega Man 7 with a robotic body with tank treads and two cannons that aren't used in-game. When the body is destroyed, the Bunby Top (ブンビートップ,Bunby Top?) head will separate from the body and follow Mega Man like a Bunby Heli, but slower. They appear in the opening stage, Burst Man's stage, Cloud Man's stage, and Junk Man's stage.
Bunby Tank DX (ブンビータンクＤＸ,Bunbītanku DX?) and Bunby Top DX (ブンビートップＤＸ,Bunbītoppu DX?) are deluxe versions of the Bunby Tank and Bunby Top that appear in Mega Man 8 and Mega Man & Bass. They are similar to the originals, but Bunby Tank DX is now able to fire missiles.
Bunby Catcher (ブンビーキャッチャー,Bunbī Kyacchā?) is an enemy from Mega Man 9 that fall from the top of the screen to catch the player, and will pull them in one direction if it manages to do so. In certain areas, especially in Galaxy Man's stage and the third Wily Castle stage, they can be very dangerous, due to these areas featuring spikes, which the Bunby Catchers can use to slam the player into, killing them instantly if they do not have the Shock Guard. If in the grasp of a Bunby Catcher, Mega Man can destroy them and break free by using Jewel Satellite, Tornado Blow, or Hornet Chaser.
