Pyrrha Nikos/History

Pyrrha Nikos graduated at the top of her class in Sanctum before arriving at Beacon Academy. Also before arriving at beacon, she became the mascot for Pumpkin Pete's Marshmallow Flakes and won the Mistral Regional Tournament four years in a row.

The Shining Beacon, Pt.2
Pyrrha Nikos made her first appearance as a cameo in the background during the ceremony in The Shining Beacon, Pt.2 after Ruby Rose leaves Jaune Arc, who wonders where he will be able to speak to another "nice, quirky girl".

The First Step
Part 1: Pyrrha is seen again in the locker room having a conversation with Weiss Schnee, who wishes to form a team with her. Pyrrha expresses nonchalance regarding partnership in the teams, and thus agrees to forming a team with Weiss. Suddenly, the two girls are interrupted by Jaune Arc interjecting and trying to flirt with Weiss and possibly form a team with her, who shoves him off repeatedly. However, when Pyrrha mentions that there are more than two people in one team, Jaune immediately goes and tries to flirt with with her, who reacts with interest and vague amusement. Weiss explains that Pyrrha is renowned for her physical ability, which shocks Jaune. He continues trying to get Pyrrha to team up with him, until Weiss runs out of patience and gets Pyrrha to chuck her spear at Jaune, pinning him to a wall and deflating his bubble of faux self-confidence, and the two leave, though Pyrrha still acts friendly towards Jaune as she passes by him.

Part 2: After being catapulted into the Emerald Forest for their first test at Beacon Academy, Pyrrha seems to purposely scope out Jaune using her weapon's rifle mode, then throws it in javelin mode to pin him to a tree. She finds him, and they become (tentative) teammates, as it was explained in part one that the first person one made eye contact with was their partner. Fan speculation is that Pyrrha wanted to be on the same team as Jaune, so she made sure she knew his location by pinning him to the tree. However, this opened her up to attack as the distance she threw the javelin was significant, and she would have had to travel through the Emerald Forest unarmed to reach him.
