Merken was a world famous professor who went from being a promising scientist and engineer to becoming a mechanical engineer and biotechnologist with outstanding talents. However, as he slowly became engrossed in the illegal research of fusing man with machine and animals, he began to lose all rationality.
In the end, his illegal research was exposed and he was thrown out of the scientist association. As he was facing the biggest crisis of his life and at the cusp of losing everything, Big Fort Company promised to fund his research. He is now working in the merchant's basement in a secret laboratory.
His pride in regards to his intellectual capacity is very high and he loves to show it off. With his desire to gain new knowledge being so strong, he will not hesitate to satisfy his it regardless of how unethical it may be.
