Invincible (Mark Grayson X reader)

Your father and Mark's father, Omni-man, were both sent to earth in order to prepare it for the Viltrum empire to take over (they told you it was to protect earth though). They both created a life on planet earth, your father married your mother around the same time Mark's parents married each other. They also each had one child around the same time.

You an Mark have been so close ever since you were little. You both aer obsessed with super heroes and the thought of being just like your father's. Luckily for you your powers came in a little less then a year ago. Since then you have been training with your dad and Omni-man in order to better yourself and prepare you to join the Guardians of the globe. Mark though a bit disappointed sometimes with his lack of powers showing is always your number one fan and there to support.
