I haven't done a drawing of Cassie Sandsmark as Wonder Girl in a while, so I thought maybe I'd give the demigoddess her time to shine for the holidays. More pics of Cassie will be coming soon in the foreseeable future.
When Miss Martian first landed on Earth, she went on an uncontrollable rampage as she knew humans were responsible for the death of her father and brothers. However, the Teen Titans, now reformed, stopped her from destroying Jump City at the behest of her uncle, Martian Manhunter. When they finally defeated her with fire, however, she went into a mental breakdown, which allowed the Titans to take her back to the tower and there they learned the truth of who she was, and accepted her as one of their teammates.
As the new Wonder Girl, Cassie Sandsmark was a bit unsure about befriending an alien who tried to nearly destroy the town, but her older sister, Troia, reassured her since she and Starfire were best buddies, and Nightstar and the other Titans got along extremely well with their new intergalactic teammate, in spite of the fact she still couldn't control her powers. Convinced, Cassie decided that she should treat M'gann as a friend, and she and Nightstar always stood by her side, even if the two did get into a friendly rivalry over Superboy.
When Christmas break was coming around, Wonder Girl stayed with Miss Martian, Nightstar, Speedy and Robin at Titans Tower while Blue Beetle and Static went home to their families for the holidays. As it was M'gann's first Christmas, she was looking forward to the event, and bought a big plastic candy cane, while Wonder Girl decided to bake a batch of miniature mince pies.
