Ryu, Parker and Jones
As the earth shook to signal the approach of the mysterious interlopers, Ryu turned his head and sank down into a battle stance. "The heroes are coming," he said, leaning onto his back leg and cupping his hands. The orange aura that normally surrounded his body during battle gathered in his hand, creating a sphere of energy. That energy grew bigger and bigger until it was the size of a watermelon.
Then, it happened. Two elephants broke through the gate, sending cars everywhere. One flew towards Parker, but he swiftly dodged, leaping over the incoming car. Meanwhile, the elephants locked onto their target, the cosplayer charging his attack in the middle of the street. Someone leaped off the top and spawned a giant fire rhino, a familiar looking skeleton pirate. Just like that, Ryu was staring down a full frontal invasion, with nothing but his courage and a crapton of ki.
"FALL TO MY POWER HEROES! FALL BEFORE THE GREATEST VILLAIN RYU!" he screamed, thrusting his arms forward and releasing a massive blast. The resulting beam was large enough to engulf the elephant, and indeed was moving toward the one handled by the knight. In the meantime, Parker sprung into action, using the fallen car as a platform to propel himself towards the other elephant. As he grew closer, his arms morphed into long tedrils. He attempted to wrap them around the other girl's elephant, tripping the creature.
A single voice echoed through the sky, filtered by the musky quality of a speaker. "Lorenzo, do not touch Ryu!" the voice ordered from atop one of the store's high story roof. If the two turn their attention to the voice, they would see a lone cyborg man perched on the edge of the building.
