Also known as: Dialga.
Calm, steady, and solid, Dialga is hard to frazzle, with an ancient presence and sense of power that is hard to place. Easygoing in societal situations, he's more interested in watching others than in actively engaging with games or other forms of play.
In combat, however, he is a ruthless and intelligent opponent, an experienced veteran who gives no quarter and expects none. Dialga's focus is more on defence than outright assault, but he's not afraid to give chase if he believes it is necessary for him to do so.
He strongly prefers to simply offer advice, rather than engage in things directly, seeing his interference as something to be rather sparing.
