Sonic the Hedgehog
Balkiry is a bird/plane Badnik created by Dr. Eggman. Balkiry have made their first appearance in Sonic the Hedgehog 2. These Badniks attack with the straight line or follow their target either at medium or high speeds like a homing missile.
Balkiry Badnik's design is a hybrid of a bird and plane. The red and grey metallic body have wings on each side, a vertical stabilizer and two rotors on its back, which makes the Badnik move on medium or high speed. The head has small eyes facing front and a yellow bird beak. They have two support legs with small wheels that resemble eagles' feet.
Balkiry's appearance in Sonic the Hedgehog 4 is more detailed, as now the support feet are removed and it has received two extra wings in the vertical stabilizer. From Sonic Lost World though, Balkiry once again retains its cartoony design from previous games.
