-3rd person POV-

"Whats going on?" Ruby asked seeing the two armored figures fight.

-A few moments before team RWBY appeared-

"Do you really think you can stop me Build?" The purple crocodile armored man asked as he attacked the second red blue and white armored figure who is most likely Build. "I'm trying to save you Rouge!" Build said as he punched Rouge sending him flying back a bit. "Don't make me laugh!" Rouge said as he got up. Suddenly there was a massive flash blinding the two. Once it died down four girls appeared but they were surrounded by strange wolf like monsters as well as a giant bear monster.

"What are those?" Build asked as Ruby asked "What's going on?"
The Grimm began to surround Build and Rouge. "Interesting" Rouge said as a purple mist emerged from his suit and he gained control of the Grimm.

-Builds POV-
After seeing these creatures and girls appear out of nowhere I thought my brother Rin had something planned but he seemed to know nothing about these creatures or the girls. Soon the wolf like monsters he somehow gained control of began to circle me. "Ice Flower!! Bumblebee!!" A young female voice said as the blond girl and the black haired girl took the monsters on the right and the white haired girl and red haired girl took the monsters on the left. "Guess those are attack combo names. No matter. I have to stop Rin." I thought as I removed my Rabbit Tank Sparkling Can and Placed my Rabbit tank full bottles back onto my Build Driver. "Transform!" I said as my armor changed and lost the white accents and some other details.

"Time for the hazard trigger" I said taking out a red button like device.

I attached it to my belt and removed the button cover and activated it becoming Rabbit Tank Hazard.

-Yangs POV-
After we attacked the Beowulf's the red and blue armies guy was then seen in a black armor which looked awesome. "You think that can stop me Build?" The purple armored figure said to the black armored man who is most likely  build. "I have something new to try out" Build said as he took out a small stick.

-3rd person POV-
Build then took out his Full Full Rabbit Tank Bottle and shook it so the bottom half would be red and twisted the top cap to Rabbit. He then folded it and placed it in his build driver and transformed into his Rabbit Rabbit form.

"Now I can defeat you!" Build said as he charged at Rouge but the Ursa Grimm got in his way. Build destroyed that thing in one punch thought. Unfortunately Rouge as well as some of the Beowolfs escapes. "He got away again" Build said as his armor disappeared and in his Places was a 17 year old boy with black hair,brown eyes wearing a green vest over a white t-shirt. His real name is Shiro

"Now Who are you four?" Shiro asked as he looked at Team RWBY
