Ralmia, Sonic Racer from Shadowverse

The master of this device is the most powerful life-form of all. She doesn't hesitate; she downs pulseless metal with a single blow.

Thanks to the quick progress of technology, we were able to develop her cybernetic systems. She is swifter than sound and rivals light, far surpassing the limits of flesh and blood. Nothing, not one thing, can touch her.
