Lore: Rallos is a ruthless Noxian Soldier of large stature that stands out by being rather patient and humble. Silently carrying out orders. One would expect someone like him to polish his martial prowess during his free time, but rallos is different. He was interested in biological enhancements and Zaunite innovations since he was a child. Reading books to sharpen his mind and collecting knowledge about Zaunite augmentation. He may had the knowledge, but not the means and resources to put them in practical use, joining the Noxian army was perfect.After hardening his body through endless battles and catching the attention of his superiors by proving his worth beyond the battlefield through enhancing a captured weakling to a strong man as demonstration, before killing him with his bare hands, Rallos eventually got assigned to assist Doctor Edmundo in creating the perfect science-enhanced killer. Suprisingly, Dr.Mundo and him got along just fine and Rallos was allowed to use his equipment to work on what he calls Biomaturgy. Manipulating flesh with liquified magic and forcing it to breach its limits.Time passed and Rallos ultimately received his own laboratory in the Noxian Capital. From here on Rallos worked towards a way to enhance his already strong body, a invention that increases strength, speed and durability. After countless sleepless nights and experiments he created his first promising prototype the "Bio-Booster".A device that pumps concentrated and altered liquified magic in the body of its user. Eager and full of self-confidents, Rallos implanted it without hesitation. Everything went according to play, everything expect for the unstable power that pulsates in his arms, causing pain, waiting to burst out and cripple Rallos for life. In response to this unforseen side effect, Rallos modified his arms further with modifications and a new semi-organic armor specially designed for him, to contain and control the overbearing power that flows through them and his body. With his new powers that complements his martial prowess, Rallos tests his, through Biomaturgy created, Bio-Booster against all who oppose Noxus, primarily seeking strong opponents that pushes his capabilities to it's limit.
