Groove is a free spirit, man. A full fuel tank and an open sky above him is all this chopper needs to mellow out and enjoy whatever good vibrations the open road brings his way. One relaxed, easy-going dude, Groove is also a bit of a loner in his soul. He doesn't make a lot of attachments to others, preferring the freedom of an empty highway, but he is always sure to be there with the love when his Protectobot teammates need his help. Groove doesn't like combat or conflict in general, and is always ready to give peace a chance. Groove combines with his fellow Protectobots to form Defensor.
