Yestin is a 28 year old dialga sandshrew fusion living in the sonic world. Admittedly, white space is TECHNICALLY his home. Being part dialga, he can match (and possibly counter) time manipulating creatures. He has the powers of dialga, sandshrew, and the elements of earth and the elements relating to dialga. His "parry" is essentially a chaos control/time stop sort of thing. He can control time around him in a manner similar to the ancient light. At times, he'd like to share wisdom in relation to the flow of time...though in some cases he can't without altering potential outcomes, leading to giving small (sometimes cryptic) answers.
