The Spinas are almost sphere-shaped robots with vague bat features. The upper halves of their bodies are purple with cyan-glowing eyes, two pointy gray ears with yellow front stripes on top of their bodies, and a white mouth panel below their eyes. The lower halves of their bodies on the other hand are silver (except for their lowest point which is purple) with two stubby yellow-tipped studs on them. They also have a gray ring around their middle. They also have spinning semicircles, which are purple, silver and cyan in color, on each side of their bodies, mimicing wings. Lastly, they have electrical currents running between their ears and wings.
After Sonic the Hedgehog thwarted Dr. Eggman in their last encounter, the Doctor disappeared while his Spinas and the rest of his Badnik army remained. Without a leader however, the Spinas were directionless and no longer a unified threat. Even so, they would still randomly attack anyone they came across (although such incidents were more accidental than aggression-based).
The Fate of Dr. Eggman
Some Spinas stationed in one of Eggman's bases later encountered Sonic when he infiltrated their base. However, they were no match for Sonic, who simply boosted through them. A bigger Spina soon after attacked Sonic, but it got destroyed by Silver. Another large Spina immediately after tried sneaking up on Sonic and Silver, only to get sniped from the shadows by Whisper. More Spinas suffered the same fate when Whisper began making her way through the base. Later, in the base's central computer room, a horde of Spinas helped E-107 Theta attacked Sonic, Silver and Whisper when the trio of heroes entered their room. However, they all got destroyed.
Battle For Angel Island
After Neo Metal Sonic conquered Angel Island and turned it into a flying fortress, Spinas were stationed around the island. When the Resistance and their allies later came to Angel Island to liberate the island, the Spina tried to stop them. However, they were no match for the heroes, especially Whisper, who took out a ton of them using some prims and her Variable Wispon.
Basically, the Spinas are mindless and silent drones programmed to follow their leader's every command. As such, when left without a leader to follow, they become directionless and only able to cause harm by accident. Under a guiding force however, they are cold and merciless machines who carry out their commands without question.
Powers and abilities
The Spinas have the ability to fly in midair by rotating their wings like propellers.
- The Spinas are based on the Spinner from the Sonic the Hedgehog video games, and use its Japanese name.
