Lycus was once a powerful and remorseless leader of Libya. On a mission to take his rightful place as his father's champion, he had a hell hound infiltrate Titans Tower and it ended up killing Marvin and putting Wendy in a coma. Afterwords, Lycus met up with his aunt, Cassie Sandsmark, and challenged her to a battle. Lycus claimed that everyone he killed made him stronger. Cassie was able to call the other Titans for help. While the other Titans were occupied with the hell hound that happened to grow to the size of a big building (most likely from gaining power from killing people as well), Lycus forced his young aunt to fight him. Lycus told Cassie that when he killed someone, he not only got more power, but she lost some of her's! He could have kept killing until she had no energy left but he wanted to beat her fair and square. Cassie tried using her lasso but found out that it didn't work anymore. Lycus stole it and started to strangle her. Cassie was about to die when all of a sudden she she realized that she always used other people's powers instead of her own whether it was Zeus' or Ares'. So she decided she wouldn't rely on anyone's power but her's. That quickly turned the tables around because she had all of her power back and even more! As she was fighting him, Kid Devil and Bombshell took care of the hell hound only to find out that all the power it had was then transferred to Lycas! The Titans tried to help Cassie but Cassie quickly stopped them and said that she had to be the one to beat him. Lycus took advantage of this distraction to attack Cassie but even with the power boost he was no match for the new Wonder Girl. Cassie threw her lasso around the beaten Lycus and then he disappeared.
Powers and Abilities
Demi-God Empowerment: He was eventually granted similar abilities by Ares to become the Earthly embodiment of the god of war. Every time he kills someone in Ares name while his champion, Wonder Girl, is near, Lycus would be granted more of Ares' power and Wonder Girl would grow weaker.
Superhuman Strength: His partial Olympian flesh and bone is about one and a half times as dense as similar human tissue, contributing to the Olympians' superhuman strength and weight.
Superhuman Speed: He can move at supersonic speeds. He can move fast enough to not register in the normal peripheral range of humans and seemingly vanish and disappear at will. At this speed, his mind processes information at least on a subliminal level that he is aware of her surroundings. He is fast enough to deflect and catch bullets.
Enhanced Durability: If he were somehow wounded, his partial godly energies would enable him to recover with superhuman speed.
Flight: Lycus can also mystically fly through the atmosphere through an act of sheer will, enabling him to soar through the atmosphere at sub-orbital levels and travel across the planet. He is immune from the effects of extreme height, such as dizziness and lightheadedness.
