Almost immediately both Evan and his brother began to grow and expand, aging to 18 year old adult minotaurs. Both brothers saw their armor fall from their hulking frames as they both grew to 6'5'' tall. While this height was normal for most minotaurs, both brothers knew they could grow larger if they continue to win - as evidenced by some of the large minotaurs watching them.
Evan now looked entirely like a minotaur like his brother - no human would ever guess Evan used to be a human. Both Evan and his brother blushed as they saw their manhoods expand and grow to adult portions - almost 10 inches flaccid with orange sized balls. Evan felt dizzy as a rush of minotaur testosterone hit his system. Evan felt agressive and powerful, ready for battle. However Evan still remembered his mission as a human. He could make out the appearance of Khad - his target - using his new improved vision. Were it not for the towering 8 foot guards protecting Khad, Evan would have charged head on to assassinate him. Evan knew he would have to continue fighting to grow stronger in order to make a head-on attack.
"Brother, let's keep fighting!" Evan boomed in his impossibly deep baritone voice. Evan forgot the fact that they were both naked, focused instead on the thrill of bloodshed.
"Yes, I'm with you. BRING THE NEXT CHALLENGE" The other minotaur called.
The gates opened and a cavern bear crawled out. This one was covered in blood and looked very healthy. Cavern bears stood almost 10 feet tall, and sported razor sharp claws and vicious teeth, making them lethal predators unlike most other ursine species. The bear roared as it charged at Evan.
Evan swiftly dodged the bear, moving surprisingly fast for a 350 pound minotaur and grabbed the bear by the hind leg. Evan didn't even think twice about using his daggers and instead flung the bear onto its back, almost ignoring the fact that the bear easily weighed 500 pounds. The bear was stunned by this move, giving Evan's brother enough time to bash the beast's head in with his battle axe.
With the bear slain, the crowd cheered. Evan and his brother were offered another chalice of Khad's special forumla. The two brothers drank it up vigorously and felt an even greater surge of power course through them. The minotaur essence that Evan was taking in was slowly beginning to infect his human mind, twisting his desires and motivations to suit Khad's will.
Evan still remained focused on slaying Khad...just after he finished enjoying this bloodshed. Might as well have a bit of fun first slaying these weaker beings. Besides, Evan craved more power, enough power to overcome and foe with his brother by his side. Evan now remembered his brother as his twin. Evan was flooded by memories of the two of them growing up together and fighting side by side, training as minotaurs their entire lives. Evan had forgotten his history as a human, but still remembered he needed to slay Khad for some reason or another.
