Wait...

You caught how one sound came back a bit fuzzy than the other two, if that's how the differences worked for bats... "That way," you say softly. You and Harleen take to the alley, looking all up and down it for any trouble. Suddenly, there was a clattering from in front of Harley: an empty tin can falling from an overflowing dumpster. It startled her, but calmed down some.

"Things go bump in the dark, Mr. S," Harley said uncertainly, anxiously.

"It'll be all right, Harley. Come on." And you both made it through the narrow passageway between the abandoned buildings, onto the next street over. There was Rudy in the purple flesh, feeding on his latest human victim. When you paid attention to the big picture, there were people lying all over the ground! Harley didn't like what she was seeing any more than you did, covering her eyes. "Rudy!" you called.

He drops his **** victim, barely leaving him alive and turns to you. "Well! Two new dishes to try," he grins as he rubbed his hands together. He strolls towards you both confidently and taunts you. "Ol' Supes must be losing his touch. I drained the whole city nearly dry, and he's a no-show!" He then walks quicker towards you. "Hope you won't disappoint me." He charges at you, and you channel the strength of a gorilla as its transparent shape lines up with yours for a few seconds. You pull your fist back and slam it against his face, sending him tumbling down the street and lying facedown on the road.

"You're like a 500-pound gorilla, Puddin'," Harley mused. "You can do anyt'ing!" Then she switched to Harleen as she pointed. "But he's not done yet." Parasite pushed himself up onto his feet, ready to grab and drain you...

He runs at you, and instead of animals, you feel the essence of both Batman and Flash within you, their see-through forms nearly coming together with yours before they disappeared...
