Darkrai (Next Gen)

Darkrai is a recurring Pokemon in the Sinnoh Next Gen Saga, however he made a cameo in Kalos Next Gen. It is able to talk via telepathy.

Kalos Next Gen
Darkrai made a small cameo watching Bella and Chimchar leave Professor Rowan's lab.

Sinnoh Next Gen
Like his first appearance, Darkrai watched Bella, Ellie, and Sam come to Sinnoh. It later saw the trio leaving Professor Rowan's lab. Darkrai appeared again multiple times watching Bella and her freinds from afar.

Darkrai revealed itself to Bella during Dawn's lesson on Pokemon Contests in Alamos Town. Infernape saw his trainer, who was in shock upon seeing Darkrai, and attempted to figure out what she was shocked over. Before Infernape could see, Darkrai fled. It later reappeared and kidnapped Bella, in the process revealing itself to the group. It was later revealed that the reason Darkrai took Bella was so it could calm Dialga and Palkia again if they ever quarrelled (it decided Bella would stay in Alamos forever in case). Infernape challenged Darkrai to a battle for Bella and in the middle she was almost hit by a Dark Void. Infernape sucessfully shielded Bella but lost in the process. Darkrai took this as a chance to take Bella, but was stopped by Chespin and Salamence. Although it tried to fight the group off, Darkrai was defeated and decided to release Bella. Darkrai vowed that one day it will get Bella to join forces with him.

Trivia

 * Darkrai decided Bella would fit the job of calming the Creation Trio since her mother had done it before
