The Spina is a bat-like badnik with blade wings attached to its midsection. These blades never stop spinning. Individual Spina have different behaviors to one another: some will lay on place, others fly around in circles or eights, and there are those who will move towards the enemy once they spot him/her.
There is an advanced model, the Spana, a Spina which discharges an electric field every now and then.
It appears in Sonic Unleashed with a new designer with cone-shaped ears, eyes and mouth and cyan and like wings with blades.
In Sonic Colors reappears with new models and a designer who seems to be a mixture of Sonic Adventure and Sonic Unleashed elements.
