MAJOR SPOILERS FOR LEGENDS ARCEUS AND THE INDIGO DISC
⚠️⚠️⚠️
Ok. It's confirmed by the indigo dial dlc that if you bring out Ogrepon when fighting Kieran, his AI will change and he gets special dialogue
So what if you could do that with nicknames?
What if in legends arceus, you named a pokemon after Emmet (or even use his Japanese name, Kudari), and Ingo has special dialogue about that name specifically. Like it triggers something in his fragmented mind that makes him remember more. What if you name a pokemon after him? What reaction would he have?
Or even for legends ZA if Emmet makes an appearance? Like, he hasn't seen his brother in....we don't know how long, at minimum over a year, and then we pull up and name something after his brother. It would be so interesting if he had some sort of reaction. Even more so if we send out a pokemon like chandelure which was his brother’s ace.
