Doom is a terrorist team that is out to destroy the LBHA. Their Leader and Mastermind, "Envy", was able to convince his members to join him in his plans. When Millennium sent out the call for the LBHA, 12 people showed up. Of those that showed up, there was Dragon and his brother, Shark and his cousin, Yeti and his twin brother, Predator and his brother, Scarab and his stepbrother, and Shadow and his brother. After the decisions were made on who was to join the LBHA, Millennium sent the other's on their way.
"Envy" saw the rejection as descrimination against one of the most disliked species, Vampraz, which he was. After the other's went their seperate ways, "Envy" went right to work. He extracted some of Millennium's blood to make a clone, and then gathered the other rejects. "Envy" convinced the others that it was either a descriminatory choice, of that they were sabotaged into not being chosen. With this clever plan, he got their kin to turn on each other. With time, the new members of Doom were chipped, and basically became obedient to "Envy" and all hated Millennium and the members of the LBHA.
"Envy" gave Doom free will on everything they did when it came to weapons and means of transportation. They each were given names that ment doom to people or to their main enemy. They then named the team Doom, and they went about their business to bring terror to the planet.
This is one of the hardest teams the LBHA has ever fought because it is composed of family members that know them inside and out. They know just about everything about the LBHA members, and even have intel on the LBHA HQ technology. Doom could bring destruction to the whole planet if the LBHA were to lose the continuing fight.
Behind the Scenes Trivia: "Envy" was originally the only person that was rejected from the LBHA test, but when I decided to make him the brother of Shadow, it just made sense to make a whole team of people that were like that who know the most intel on their enemies. It would make a great threat, kind of like the Green Goblin and Spider-Man. And that's how Doom came to be.
