Blade Tigrerra. or simply known as "Tigrerra" is a Bakugan and the evolved form of Tigrerra. She is the Guardian Bakugan of Runo Misaki.
Runo Misaki's Haos Tigrerra became a Haos Blade Tigrerra after evolving. She took on this form when she and Runo went to the Doom Dimension, in an attempt to rescue Dan and Drago. When she and Runo were forced to battle a younger version of Dan and Lars Lion, she was almost defeated. Fortunately, Runo was able to confess her feelings, which allowed Tigrerra to evolve into Blade Tigrerra. When Dan was battling everyone to help Drago evolve, Tigrerra wanted to battle Drago but was afraid that with Shun and Storm Skyress before them, she may not get her chance, so she requested that they battle first, which everyone was okay with. She lost, however. She has been in multiple battles since then, mostly in order to restore Vestroia. She stayed in this form up to the point where she must return to Vestroia.
In the first episode of Bakugan: New Vestroia, Blade Tigrerra is seen as one of Baron's Bakugan battling with Mega Nemus against Viper Helios. She was defeated trying to defend Baron's Guardian Bakugan, Mega Nemus. Blade Tigrerra was later turned into a statue and stayed there for most of "New Vestroia." She was the second to last of the Six Fighting Bakugan that were captured. It was her capture that prompted the Legendary Soldiers of Vestroia to send Drago back to Earth to get help.
And she is voiced by Kira Buckland in the English dub and reprised by Atsushi Ono in the Japanese dub.
