Buzzer

Buzzers are robotic bee enemies from the game Sonic the Hedgehog 2. They are flying foes that appear in the Race to the Finish version of Emerald Hill Zone

In Super Smash Flash
Buzzers are yet another aerial enemies in Super Smash Flash, alongside Flying Goombas, Beezleys, Mayu Birds and Pearl Birds. As stated above, they only appear in Classic mode and Adventure mode, as enemies in Race to the Finish. They follow the player around trying to "sting" them. They give around 12% and weak upward knockback. One hit is enough to defeat them, like all other minor enemies in Adventure mode.

Trivia

 * The Buzzer's sprite in SSF has transparency flaw on its tank and abdomen.
