Heartwarming / Pokémon: Lucario and the Mystery of Mew

  • I thought it was cute when Max offered Lucario some of his chocolate. Lucario (who's never had the stuff before) tries it, and likes it.
  • When Lucario is able to hear Sir Aaron's final words through a Time Flower.
  • When all the humans are being eaten by the Tree's self defenses, their last act as trainers is to release their Pokémon so they're not eaten too. Real Tear Jerker moments here people.
    • Even James of Team Rocket releases his Pokemon, telling them to save themselves before disappearing.
    • Jessie was the only one not to, but she didn't really have a chance.
  • Post credits Sir Aaron and Lucario split a bar of chocolate.
  • Meowth reuniting with Jessie and James may very well be one of the cutest moments in the entire series.
