Biography
Deathowl was born in the Malastarian homeworld of Zoness and he is a crossing between an owl, human and insect. Since childhood, Deathowl was trained to kill and his skill with the sword, kunai and theatrics have impressed his masters including Fyrus, who offered him a title of General. Deathowl was more than pleased as he loved to fight and kill innocents without remorse, making him one of the most feared warriors in the galaxy. Many worlds including his troops quaked with fear, with the mere mention of his name as he was brutal, sadistic, bloodthirsty and extremely intolerant towards failure. His other abilities include shapeshifting.

Deathowl fought on planet Earth during the Malastarian war and brutally eliminated the Ninja Storm, Samurai, Lightspeed Rescue, Turbo, Lost Galaxy, Overdrive and even the Megaforce Rangers could not stand up to him. While fighting the Megaforce rangers, he encounter Beverly. Upon seeing how they died, Beverly engaged in a hand-to-hand combat without showing any fear. Deathowl respected opponents who did not fear him, but still preferred to kill them. When Beverly was pinned, he was about to kill her until Troy Burrows, with the last of his strength stabbed him in the leg with his Dragon Sword.

Beverly took the chance to shoot him three times in the chest, injuring him and angrily choosing to escape vowing revenge on Beverly. Five years later, he flew to the villa where Joanna and Beverly were staying and attacked them. He toyed with Beverly's lover, prompting her to stop fighting. But he tricked his nemesis and shot Joanna from behind. In a fit of rage and the need for vengeance, Beverly attacked but was badly beaten and stepped on her back so hard cracking her ribs. He then stabbed Joanna, killing her.

While in Global Army HQ, he posed as a scientist and tortured Trey for information on the Centaurus Bracelet. Trey released himself and fought the evil assassin, but was overpowered and mortally wounded. Compromised, he escaped from G.A. HQ. Before the final battle, Deathowl battled against Yumi and Beverly in which the two rangers finally avenged their fallen loved ones and friends. Before he died, he signaled Fyrus for a final attack on Earth and tells Beverly the last words of Joanna, which were "Dont kill her!"

More facts will be known in the sequel.
