Ronan the Accuser, angry about a peace treaty which ended a war between the Kree and the Nova Corps of Xandar, hoping to bring genocide amongst the Xandarians for killing his family. Ronan began working for Thanos, who was searching for the Orb, in exchange for a promise from Thanos to destroy Xandar. Ronan was then ordered by Thanos to attack the planet Kylos.
Following Thanos' quest for balance in the universe, the population of Kylos was randomly divided into two groups, and one of the groups was slaughtered. Drax the Destroyer, who was in the surviving group, watched Ronan the Accuser personally kill his wife Ovette and his daughter Kamaria. The two screamed and Ronan laughed, finding their screams pitiful.
Drax the Destroyer swore revenge on Ronan the Accuser for the murder of his wife and daughter. He began his quest for revenge and was eventually arrested and sent to the Kyln, where he came across Gamora, recognizing her as someone who worked for Ronan. However, Peter Quill convinced him not to kill Gamora, as she could help him get to Ronan.
While Gamora, Quill, Rocket Raccoon, and Groot talked to the Collector, Drax slipped away and called Ronan to Knowhere, leading to a fight between Drax and Ronan, in which Ronan claimed not to remember killing Drax's family. However, Ronan later taunted Drax with their memory, and Drax helped the other Guardians of the Galaxy to kill Ronan. He then focused his mission of vengeance to Thanos,. Four years later, Drax unsuccessfully attempted to exact his revenge on Thanos on Knowhere, muttering Ovette's and Kamaria's name. Despite his failure, Drax was involved in a major battle which led to Thanos' death, meaning that Drax had finally avenged his family.
- "Wait. You are the Star-Lord. You saved my home world from a Kree invasion."

In an alternate universe, Ronan the Accuser led the Kree to invade Kylos to slaughter its population. However, thanks to the efforts of T'Challa, the Kree invasion was aborted and Kylos was saved after six days. As a result, Ovette and Kamaria were never killed, leading Drax to become a good-natured and funny bartender. One day, Drax met with Star-Lord and took two selfies with him for his family after praising him for saving his homeworld.
