Kabasiras are small, rather creepy-looking insect-based Badniks. They have a round, grey body with small wings, black eyes and red nose. While flying, they create a trail consisting of a few after-images which follow their movement.
In Sonic the Hedgehog CD, the Kabasiras are only found at Stardust Speedway. In gameplay, Kabasiras normally fly up and down in one place. When the player approaches, it will fire an afterimage in the playable character's direction. While their afterimage can damage the player, it can be intercepted the mid-air with the Spin Jump without causing the player damage.
In the Bad Future or sometimes in the present timeline of the Rounds, Kabasiras are one of the few Badniks who do not show decay, thus remaining pristine in appearance. However, these Kabasiras are slower but do not fire their afterimages. These Badniks can easily be defeated with a simple Spin Jump. Like every Badnik in the game, they are powered by Little Planet flower seeds which will pop out of them after being defeated.
- "Kabasira" is the Japanese word(s) for "Mosquito Column" or "Swarm".
