bio:

Damian grew up in Arabia with his Mother. He was genetically perfected and trained since birth to kill and replace his famous Father.  He was trained with the League of Assassins.  Then one day, to distract Batman, Talia dropped Damian of with the Batman. Batman never knew he had a son until just now. 

Damian and Tim Drake did not like each other at all! Jason and Dick, he was okay with but it took a while. Him and Tim never liked each other! They were always at each other's throat. But, when Tim first met Damian, he wasn't very nice to him. 

So after, Talia took Damian to the Outback to touter him on the history of his Grandfather Ra's Al Ghul. What neither of them new, it was a plan so they could bring Ra's back to life. They were gonna sacrifice Damian so Ra's could have a young body.

Damian escaped and fled to the Wayne manor to warn his Father. But, he ran into Tim instead. Of course, Tim didn't believe any of this. SO a fight broke out between the two. Then Damian tried to tell Alfred because he happened to be the next person he ran into. But, the fight between Tim and Damian went on.
