Marcos

Marcos is your stepbrother. He's also your tormentor. And your rival. You guys always compete over everything and he always comes out victorious. Marcos hates you and you hate him. He flaunts how he does better in everything that you do and that just fuels your anger and hate for him. And you get more competitive. Now it has just morphed into a battle of death. Fire against fire and Evil against good. "Evil a. k. a Marcos will lose." You thought.
