Amazing! You've brought the same level of entertainment with your newest iteration, but now you've managed to inject heart and character into TCO! Now it's satisfying on more then just a visceral "pew pew boom boom" level!
If this series goes keeps going from here, I'd imagine you bringing the old Chosen One back (perhaps the Animator cheeped out and used components from his old machine that are still "infected"...?). But he finds TCO calling himself The Chosen One, and gets pissed. Going further, perhaps the Dark Lord and Original TCO merged to survive the destruction from before, but the process caused the new entity to go nuts.
Opens the way for more battles and also even some interesting "deep" conversation ("He enslaves you and your friends for entertainment, just like he did us!" "No, he's good now! I showed him the light and we work together on stuff!" "Fool, you live in a gilded cage, open your eyes!" etc).
Regardless of where you go next, this is an amazing video, and I hope to share this with my friends in the future!
