Klunk has no memory of who is parents are, and had no one to raise him. He lived in Steam Zone for his entire life, and was raised in the streets. When he reached the age of 21, he joined up with a local gear factory, and was given the name Klunk, due to the fact that he kept dropping gears and that's the sound that it made. He was well liked by his fellow co-workers because he never made a fuss about anything and never complained. He was always a tough person, due to the fact that he was raised on the streets, but that all changed. When he was loading a crate with gears, he saw something in the ccorner of his eye. It was a small rose growing out of the ground. This was a rare because the Steam Zone has no plant life what-so-ever. He had never seen anything so beautiful in his entire life, so he took the flower and kept it for himself. That's when his soft side developed within him. And for once in his life, he felt happy. But that was all about to change.
When Dr. Eggman invaded Steam Zone, he was one of the few that escaped from Eggman's grasp. He was enslaved and was forced to work in the engine room of Eggman Land. He knew he had to escape, and that's exactly what he did. Using his brute strength, he forced his way out of Eggman Land and retreated to the outskirts of Steam Zone along with his childhood friend Steam the Hedgehog. He managed to save the rose while he was escaping and he placed the small rose in a glass case and hid it in a crate. Everything that he had worked for was lost all thanks to Dr. Eggman. He wanted revenge on the doctor, and Steam was the one to help him get that revenge. Together they formed Team Steam, a group of rebel's that will fight to save Steam Zone and to defeat Dr. Eggman. In its early stages, they accepted Craig the Robin in thier ranks. Klunk took a liking to Craig, and became a big brother role for the young bird.
Klunk is the muscle behind Team Steam and can break anything that stands in his way. Even though he is a tortoise, he can run really fast, but not as fast as Craig the Robin and Steam the Hedgehog. He can detach his shell of his back and he can throw it to attack enemies. His shell can also be used as a shield.
