I don't own any Bakugans or Brawlers expect for Sierena/Saraphie, Selena/Storm, Baku-flower, Rose, Ralph, and Getto/Macho (Mac-ko). The dark siblings are Rose and Ralph who are half bakugan. The other three have the power to change into a bakugan (their true form) and human(their cover form). The Ang sisters are Sierena and Selena, Dan had beaten Selena 5 times while only beating the older sister once (He nearly died...). This is my version after the last bakugan episode.

In a dark cave where nobody can see anything there was a conversation going on, there seemed to be a female and two males talking about something. "I want them all dead, nowww..." A deep, rough voice spoke in the cave, his voice sounded like pebbles going down and clanking on the cave's floor. "Yes of course sir, but the bakugans?" A timid voice spoke through out the the cave, "Ah yessss, the bakugans. I believe they might join us better then usual? Don't you think so masster? I think tha~" The feminine voice was cut brutality by the person who spoke first. "No Rose I believe that the bakugans might want revenge for their... friends, but yes we will see..." The timid voice spoke up again, "Sir, d-don't you think, tha-that the brawlers might join us too?" The voice was darker then ever, "Hmmm, you might be right Root, we will threaten them if they stay alive that is, first try to kill them, then if they're still alive it would mean they are worth to live, but if they refuse they have more the reason to die." "I-it's Ralph sir..." "Of course Ralph is so timid," Rose spoke staring at her brother with disgust. "I can get the job done masster, and~" "You're a chatter box," spoke Ralph. "Both of you quit it, you both can be generals, but make the bakugans do the work." "Yes sir!" "Yes masster."
Dan was coming back to his home after 5 years with his best friend and bakugan Drago, "Drago? Do you think they can forgive me for missing out? I wonder what they are doing now..."
While Dan was still away the Dark Siblings destroyed the city, "Wow this is so easy without that pest Daniel." "You are sooo right Rose bakugans go!" They never attacked Shun's grandfather's house however for it was forsaken and protected by a barrier the siblings couldn't get through. Most of the people stayed there and brought food along with them, but it wouldn't last forever. The more people came, there was less room. They had to bulid underground rooms for each other and it never flooded. Sierena in bakugan form put up a force field but only for Shun's grandfather's house for it already had alto of protection. But soon they were in a starvation, Shun went to look for food never to return... and their savior came...
