Sulkan Massacre

''"I will always hate El Doryu for what he did to my people. He slaughtered them all. Men, women, and children. And yet he acts like he's the type of person who wouldn't massacre billions of people. Well let me tell you: El Doryu is pure evil. He is a wolf in sheep's clothing, and he will kill everyone if given the chance." -'' Fiora The Sulkan Massacre was a massacre caused by El Doryu and his Skull Legion, combined with the Kyrion Army. The Phoenixgarde Army fought against the invaders in a desperate attempt to survive and defend their home.

El Doryu's sanity
El Doryu has two distinct personalities: A lazy personality and a bloodthirsty personality. El Doryu's more dominant, bloodthirsty personality began to kick in, and eventually, the skull overlord's mind was completely taken over. El Doryu wanted to go on a hellish rampage because he felt like it. He allied himself with the Kyrion Army and, along with them, invaded the planet of Sulkan.

The Deadly Alliance
El Doryu and El Kraßler became allies after El Doryu threatened the latter, which merged El Doryu's Skull Legion and El Kraßler's Kyrion Army, creating the "Deadly Alliance".

The battle of Sulkan
El Kraßler's army invaded, and the Phoenixgarde army fought back hard, but they were easily overcome. El Kraßler's forces already had the advantage, but eventually the momentum of the battle shifted in the Phoenixgarde army's favor. El Doryu and his Skull Legion decided to step in when the momentum shifted, which struck fear into the Phoenixgarde army. All Along The Watchtower possessed numerous tall buildings on the planet's surface, and used them to blow up enemies trying to close in on El Doryu and his army. Dissatisfied with how boring the battle was, El Doryu blew up the entire planet after El Kraßler departed, and El Doryu continued his rampage on nearby planets, expanding his Skull Legion as well.

A wounded galaxy
After the battle, many inhabitants of the Lost Galaxy were very terrified of El Doryu, and he immediately became feared by the inhabitants of the Lost Galaxy.

The Galactobeasts were also awoken whenever El Doryu attempted to blow up Sulkan, and although they could not do much to defend against the destruction of Sulkan, they realized then that El Doryu's existence was a massive threat to their galaxy, as well as reality itself.
