Sonic the Hedgehog
Orbinauts are said to be based off
sea urchins ( uni in Japanese). Orbinauts are different colors of metal orbs which are able to hover in the air. This badnik's signature weapons are four spiked balls that ringed around of them. Some of Orbinauts throw at its prey which is its only method of attack for some of these badniks. This is also a major weakness; as once all four spiked balls have been thrown, the hovering Orbinaut itself is completely defenseless.
However some of Orbinauts don't throw its spike balls away, but keep moving forward and keep ringing its spike balls at same time as keeping its defense on. Usually it's impossible to defeat these types of Orbinauts without getting hit, which is good to avoid them and keep moving on. Few of Orbinauts utilize its spike balls with different methods to stop the player.
