As Team RWBY prepared to do battle, all of a sudden- 

Hepheastus: STOP! YOU'L NEED THIS! 

He tossed Ruby a special sword! 

Ruby: What is this? 

Hepheastus: This was the blade of the mighty warrior, Achilles. He was known for his invulnerability! With this, you will be able to channel his power. 

Blake: Wait, what do I get? 

???: This, young Belladonna. 

A beautiful woman in armor appeared. 

Athena (The Goddess of Wisdom! And daughter of Zeus! She is one of the many Gods who defends humanity from her father! A very wise and motherly woman! Voiced by Colleen Clickenbeard!)

Blake: A-Athena? 

Athena handed her a special sword. 

Blake: What is this? 

Athena: The Sword of Wisdom. With this, you will call upon all of the knowledge of the Gods, and the power of Olympus will assist you. 

Blake: Th-Thank you. 

Ares: So, in the end, it really is fated. YOU ALL WISH TO BE SLAUGHTERED BY ME! FINE! LET THIS BE A FINE START TO A GLORIOUS WAR!! 

Ruby: You're a monster, Ares! Just as evil as your father! 

Ares: Once this is over, I'll be his favorite! 

He took out his strongest weapons! 

Weiss: What are those? 

Ares: The Blades of Chaos! These are my strongest weapons! And with them, I will rip you to shreds! 

He started throwing the blades at the four girls as Ruby spun the Achilles Sword like a fan to deflect the attack, only for the Blades' chains to wrap around the sword. 

Ruby: HEY! 

She pulled back as hard as she could, and felt a burst of strength flow through her! 

Ruby: HA! 

She pulled Ares right towards her, and then- 

Ruby: HIYAH! 

She punched him with an Armament Haki punch, and- 

Ruby: RASENGAN! 

She blew him away! 

Ruby: YES! 

Ares: DAMN YOU! 

He used the chains to grab her and pull her over! 

Ruby: AAAAAAAAAAAAAAAAAAAAAAAAAAGH! 

Weiss and Blake: RUBY! ICE MAKE: ARM! SHADOW HAND!!! 

Weiss and Blake pulled her back as Yang grabbed the chains while entering a form that was a fusion of Gate of Death and the Cerberus Armor! 

Yang: DON'T TOUCH MY SISTER!!!! 

Ares: How do you keep that going?! That almost killed you! 

Yang: THIS IS THE STRENGTH OF HERC! THE GOD OF HEROES AND HUMANS! NOW- FROM ZERO TO HERO UPPERCUT! 

She hit Ares so hard that his jaw dislocated! 

Ares: WHAT?! How- 

Then a bunch of shadows held him in place as his body was running cold, and night fell. 

Weiss: Domain Expansion: Winter Season. 

Blake: Domain Expansion: Endless Night. 

Ares saw the blackest of nights and felt a cold weather going through his body. 

Ares: What is this? Why do I feel so- 

Then he felt shadow dogs biting his body! 

Ares: AAAAAAAAAAAAAAAAAAAAAAAAAAAAARGH! 

And a bunch of flaming ice spikes were going into his body! 

Ares: WHAT THE HELL IS THIS?! WHAT DID YOU DO TO- 

His mouth was frozen shut as pain coursed through him. 

And then- 

Ares: MMMMMMMMMMMMMMMMMMMMMMMMMMM! 

The blade of Athena was stabbed into him as energy was drawn out of him. 

Blake: Sorry, Ares, but it's over for you. 

He dropped the Blades of Chaos as Ruby quickly grabbed them. 

Ares would die, slowly but surely. 

Ruby: Come on, let's get these to (Y/N).
