The LEGO Dimensions are saved/Welcoming Lapatra to Chima/The Overlord swore revenge

Here is how the LEGO Dimensions were saved in The Overlord Returns.

With the battle over, Bansha reminded Twilight what to do next.

Bansha: Twilight, you can still work your magic to fix everything.

Twilight Sparkle: Right, Bansha. And thank you for your help.

Bansha: My pleasure, Princess Twilight Sparkle.

And so, Twilight worked her magic to correct all the damages.

Vitruvius: At long last, the prophecy has been fulfilled.

Shifu: Yes, Vitruvius. And it's all thanks to you.

Sensei Wu: You made up the prophecy and the heroes you described made it true.

Fluminox: Indeed, Wu. They have done well with the Overlord defeated once again.

At last, peace has been restored to the LEGO Dimensions and Equestria.

Later at Chima, everyone and everypony celebrated the birth of Lapatra.

Lapatra: (cooing)

Li'Ella: That's right, Lapatra. Welcome to Chima.

So, Po, SpongeBob, Twilight, Lloyd, Emmet, Wyldstyle, Batman, Gandalf and their friends witness the wonderful moment.

Meanwhile in Tartarus, the Overlord swore his revenge after breaking himself out of the ice.

The Overlord: This isn't over yet, Dragon Warrior! I will have my revenge if it's the last thing I do!

Until then, all the LEGO Villains along with Lord Vortech and the Overlord waited until they're ready to strike again.

The End
