Springer (スプリンガー Supringā?) is a Doberman Pinscher robot dog that guards the Silver Carcass. He was built by Dr. Koga before Metalder as his "older brother". Capable of human speech, he repairs Metalder and runs the machines inside the Silver Carcass. Springer enjoys watching TV, particularly anime.
