Resurrecting Arcturus and the Anacondrai/Five Serpentine Leaders together

Here is how Arcturus and the Anacondrai returned in The Overlord Returns.

With measures needed to be taken, Morro gathered Twilight, Sunset, Starlight, Mirage, Star Swirl, Stygian, Fizzlepop Berrytwist and Sunburst in order to cast a certain spell.

Morro: We won't have much time.

Star Swirl the Bearded: Twilight, Sunset, Starlight, Mirage, Stygian, Fizzlepop, Moon Dancer, Sunburst, it's time. (to Morro) We're ready, Morro.

Stygian: Do you think it'll work, Fizzlepop?

Fizzlepop Berrytwist: Only one way to find out, Stygian.

Morro: The time has come to resurrect and revive the entire Anacondrai along with Arcturus!

And soon enough, Arcturus and the Anacondrai have been resurrected and revived.

Arcturus: Where are we?

Morro: You're in the Ninjago Realm, Arcturus.

Pythor P. Chumsworth: Morro, Princess Twilight Sparkle and her friends revived you and the entire Anacondrai along with you.

Arcturus: How can I ever return the favor?

Skales: We start by helping our friends defeat the Overlord and Lord Vortech!

Fangtom: (right head) If we don't act now... (left head) The entire LEGO Dimensions will be doomed.

Acidicus: We'll need all the help we can get to help our old and new friends.

Skalidor: Will you help us, Arcturus?

Arcturus: We would be honored. And Pythor, I'm passing my Anacondrai Leadership to you.

Pythor P. Chumsworth: You have my support, Arcturus.

Soon, the Five Serpentine Leaders came together.

Pythor P. Chumsworth: For the sake of Ninjago!

Skales: And for the sake of the LEGO Dimensions!

Fangtom: (both heads) We shall fight alongside our allies!

Acidicus: Defeat the Overlord and Lord Vortech!

Skalidor: And help the chose heroes fulfill the prophecy!

With that said, they raised their staffs as a sign of their support to their friends.
