One last goodbye for Ash and Greninja
The one were...we say goodbye to Greninjanote As the twerps travel one last time, they are interrupted by the last fugitive member of Team Flare: Xerosic! He reveals plans to resume Lysandre's work and continue to remake Kalos in his image...and perhaps get some revenge on Clemont.
This episode contains examples of the following tropes:
- Evil Cannot Comprehend Good: When he is captured, Xerosic still can't understand why Clemont did not submit to his Mind-Control Device.
- Hidden Eyes: At one point, Ash again lowers his head so the brim of his hat hides his eyes, something frequently done when he parts with one of his Pokémon.
- Hollywood Skydiving: Xerosic jumps out of his plane to escape the twerps. Clemont grabs him with his Aipom Arm.
- Invisibility Cloak: Xerosic's plane can go invisible.
- Mind-Control Device: Xerosic wants to use Clemont's genius to advance Team Flare's work to re-gain control of the Zygarde. And he won't take no for an answer. In the end, however, Clemont had a device for just such a contingency.
- The Promise: Bonnie wants Squishy to join her when she begins her own Pokémon journey.
- Put on a Bus: Goodra is released once more to protect the wetlands of Route 14. And Ash-Greninja is released to help Squishy and Z2 exterminate the remaining fragments of the Giant Rock that Lysandre used to build the fake Zygarde.
- The Remnant: Xerosic tries to form Team Neo-Flare, but his plans come to a quick end.
- Took a Level in Badass: Greninja's transformation into Ash-Greninja becomes permanent.
- Underside Ride: The twerps think Xerosic ran over Ash-Greninja with his van. But really it ducked under and grabbed onto its undercarriage. Using their Bond, Ash was able to track Xerosic as a result.
