I have MANY reasons for liking Rowen best out of all the Ronin Warriors.

#1 He is the hottest of them all. (ahh Rowen)

#2 He has the kewlest armor

#3 He is a Libra just like me

I really like his armor because I have always been obssessed with clouds and anything to do with the sky. And of course, his armor is strata.

Background
Rowen of the Strata is the most cunning of the Ronin Warriors. He wears the Armor of Strata and wields a bow and arrow.

Powers and Abilities
Rowen's Armor of Strata is moderately powerful compared to the other Ronin Armors. His weapon is a bow and arrow. A special quiver on his back produces arrows as he needs them and never rounds out of shots. Rowen's special attack "ARROW SHOCK WAVE!" allows him to shoot one massive energy arrow at his enemies. This attack seems to gain more power the longer Rowen concentrates on building the attack.
In addition to his armor and weapons Rowen is not only the most cunning of the Ronin Warriors but the quickest as well. He never gets caught off guard and cannot be fooled by mind games.

Weaknesses
Rowen is cunning, intelligent, and a good fighter, he possesses no specific known weaknesses. I just learned that Rowen has an IQ of 250!! gosh! What a genius! The perfect guy..ahh...Rowen!
