Reshiram nodded. "It is true, my role in the world is abstract and not well-defined. In truth, it is more of a figurehead role; my true role in this world is to act as one of Arceus' enforcers, should something truly terrible happen. For example, should your presences in this world have been something of evil... that we could combat, to our greatest ability... I would have been called upon to face you, along with my sisters, alongside Arceus."
His tail engine whirred softly. "Should I need to, I am able to see the truth in all things that are near me. Disguises, illusions, even hidden desires and intents are known to me completely and without fail. Zekrom, meanwhile, has a power that is something... related to Kyurem. Zekrom can see the best futures within those she sees... and Kyurem can see the worst. Typically, neither happen... but they are what they can work toward, and avoid."
