You, Team RWBY, Rainbow Dash, and Fluttershy were all relaxing on the mansion's roof. 

Rainbow: Man, this really is some good sun. 

Fluttershy: Yes, it's one of those days when you can just look at the world and appreciate what we all have. Being one with nature, with the flora, and the beautiful fauna. 

Ruby: It's like all the universes are one. One and united. 

Yang: Yeah, really going with the spiritual stuff there. 

Weiss: Sounds like one of Tsukasa's circle of life speeches. 

Blake: I'll say- 

???: My children. 

You all heard the voice of a very familiar mask. 

Rainbow: Who is that?

(Y/N): Hey, that voice- Aku Aku? 

Aku Aku: Yes, it is me, (Y/N). You all must come, for we have no time to waste. 

Fluttershy: What happened Mr. Aku? 

Aku Aku: It's horrible, Uka Uka, my evil brother, is free. 

Meanwhile... 

Cortex: Wait! Mighty Uka Uka, I can explain! 

Cortex was getting chewed out by an evil-looking mask! 

Uka Uka (An evil witch doctor mask, and Aku Aku's brother! He is Cortex's master and has the desire to rule the multiverse by plunging it into utter chaos! A pure evil monster who will stop at nothing to achieve his goals! Voiced by John Dimaggio (The Voice of Dr. Drakken, Jake the Dog, Bender Bending Rodriguez, the Scotsman, and Schnitzel!))

Uka Uka: NONE HAVE FAILED THE MIGHTY UKA UKA EVEN ONCE, BUT YOU CORTEX, YOU FAILED ME TWICE!! 

Cortex: Please, you must understand, it has been that rotten bandicoot! He keeps standing in my way! 

Uka Uka: From deep inside my temple prison, I sent you simple instructions to follow. BUT YOU HAVE LOST THE GEMS, YOU HAVE LOST THE CRYSTALS, AND I HAVE LOST MY PATIENCE! There is now no other power source on this planet. 

Cortex: I know we've had some ... minor setbacks. 

Uka Uka: AND FAILED! But, since your bumbling has managed to set me free, I am feeling ... generous. There is still a way to amass the power needed to enslave this miserable planet. And this time, this time, the great Uka Uka will make sure you do it right! 

Behind him a scientist with a big clock on his chest appeared. 

Dr. N. Tropy (An evil scientist who specializes in time travel and quantum warp technology! He is a power hungry evil man who is willing to work with anyone to help him conquer the world! Voiced by Corey Burton (Who also voiced Zeus!))

Soon... 

You and the girls reunited with Crash and Coco! 

Coco: HEY GUYS! 

Ruby: COCO! CRASH! 

Crash: (excited gibberish)

Fluttershy hugged them! 

Fluttershy: It's been too long! 

Rainbow: So, what are up with the foxes? 

Weiss: They're bandicoots. 

Rainbow: Really? 

Aku Aku: Yes. 

Rainbow: WHOA! 

She jumped at the talking mask. 

Rainbow: The mask is talking. 

(Y/N): Yeah, he talks. So, what's up? 

Aku Aku: We are in the Time Twister Machine. My brother and Dr. Cortex have sent their men out to find the power sources throughout time. We must collect them before they do. 

Rainbow: Cool, cool. This should be fun.
