Lars Lion in her disguise
Lars Lion in her true form
Lars Lion was the HaosLegendary Soldier of Vestroia. She wore knight armor protecting her upper body. In ball form, she opened similarly to Reaper.
She was the one who tested Runo. She was originally disguised as an old woman who told Runo where an Illusionary Dan was. When she revealed herself, she outright told Runo to stop being so stubborn, but Runo would not listen.
She almost won using the most powerful Haos Ability Card, Sagittarius Arrow, but she was defeated after Runo learned to stop being so stubborn and to listen to her friends, and Tigrerra evolved into Blade Tigrerra. The result itself is not seen because when the battle is almost over, Lars Lion says that Runo has learned not to be stubborn.
After nearly being defeated by King Zenoheld and his Farbros, Lars Lion gave her Attribute Energy to Mega Nemus, forcing Mega Nemus to evolve into Saint Nemus. Directly after transferring her Attribute Energy to Mega Nemus, she passed away along with the other Six Legendary Soldiers of Vestroia.
And she is voiced by Cate Blanchett in the English dub and reprised by Ryoko Ono in the Japanese dub.
