The three siblings have started training for four days like this ever since the incident involving X and Fantome occurred three days ago. From that day, Dynamo became increasingly worried, predicting if Silhouette wasn't stopped from causing more terror, entire worlds and civilisation could be placed in complete danger. Not to mention the justified murders that have been going around from the East to the West.
There were multiple chances to request for help, but he believed that it would reel in more trouble. With help or without help, he knew that he wouldn't get out of the situation unscathed.
A few minutes later, we see Dynamo pulling out a whiteboard, and a board-holder out of nowhere. After setting up, he grabs a pitch black board marker, and draws something. Seen in the drawing are three figures that represent the trio, although not much detail was put into them. Setuh, Rico, Brickina, and Byrd sit in front of Dynamo as they listen carefully.
"This over here... is us!", Dynamo taught, "Minus Rico and Brickina. They aren't really part of the whole thing."
"Nevertheless, this is us right now. I hope you still remember the form that we have gained over the past couples of months."
"Oh yeah! The... The uh... Sin's Marathon?", dumbly guessed Byrd.
"Correct!", Dynamo continued, "These are the forms that rely on the negative emotions of our race. Since our previous battles with Corbin, we have gained access to these forms, without knowing how to completely control them."
While he says this, he draws an extra set of their representative figures, but they look darker in appearance.
"So... we're using these forms in order to beat Silhouette, right?", insured Setuh.
He nodded.
