Wayne Tower - Gotham City

The tower was a wonder of steel and glass. At over 1,000 feet tall, it was the second tallest building in the city, and was one of the tallest in the country. A giant neon white 'W' of Wayne Enterprises lit up the night sky, the shape resembling a Bat-Signal. The structure's name was in smaller letters below the W, and twin observation decks shot out diagonally from either side.

A black helicopter hovered just above a deck, and two figures dropped out, each laden with gear. The chopper moved over to the other deck and landed. The engine cut off, and the rotor blades slowed.

On the left observation deck, Grodd held the black box with the Oscillator. He attached a long cable to one side of the box, and held out the flat, bulky end of the long cable to Owlman. He took it from Grodd, eyes narrowed.

"At this height, combined with the electric current of that wretched logo, the Oscillator's powered up state from that lab, and the genius of my device to bring it all together..." Grodd proclaimed grandly.

Owlman scowled at him in irritation. Grodd's mouth tightened to a line and he gestured absently.

"Just attach the cable to the W," he said flatly to Owlman.

"I won't bother arguing with you about leadership," Owlman said in a clipped tone. "Our shared goal is too important, and time's short."

Grodd eyed the man slyly. "Yes, our goal. Wise...for a human," he noted.

The gorilla hunched over the keypad that jutted out from a side of black box, focused on pressing the keys with his massive fingers. Owlman, holding the cable, walked to the edge of the railing, hopped over it, and landed on top of the logo, ready to slap the magnetic end to the steel below his feet.

A blast of laser struck the end of it with a high-pitched zapping sound, knocking it from his grasp. The cable end clattered to his feet, not yet attached flush to the surface. Clover cut off her Lipstick beam, then flew higher and aimed towards Grodd's device as she neared the observation deck. Sam and Alex were right behind her. The ape countered with blasts from his own boxy white laser blaster.

"Oh no you don't!"cried Alex, who tossed her pair of spherical earrings to the rooftop at Grodd.

They exploded with a loud whooshing sound, smoke obscuring Grodd. Loud coughing and angry muttering was heard from within the cloud, but the loud noise of a helicopter's rotor blades caused the spies to turn in surprise. It blew the smoke away, and Bowman leaped out to land on the deck, firing an arrow with a blue cylinder at the end. Concentric waves shot forth, causing the spies' jetpacks to stop functioning.

"Whoaa!" all three of them cried in alarm.

Clover landed in a crouch on the observation deck. Sam managed to grab hold of the railing as she fell. Alex fell from further away and started to scream, but hit her heart-shaped belt buckle to cause it to shoot up to the railing near Sam. The buckle wrapped around railing, held in place magnetically.

Alex swung down towards the building and hit a giant shatterproof window with both sturdy boots, bending her legs with the impact. She then retracted the cable to rise up towards the deck, wind from the chopper blowing her hair about.

"How'd you find us, sweetie?" Bowman asked Sam, and fired an arrow.

She gasped and swung to the side, and it narrowly missed her, deflecting off the railing. She exhaled out heavily from the close call, eyes fixed on Bowman.

"We put a tracking device on your quiver. And we're crashing your party," she added.

The superspy pulled herself up before Bowman could aim another arrow. She aimed a Laser Lipstick shot at his bow, clear of his head, splitting the weapon in half. Bowman recoiled slightly, then held both halves as dual melee weapons.

A legion of black drones, identical to the ones at the lab, lifted up into view, guns aiming at various heroes. Beetle morphed his hands into ten finger blasters, picking off a number of drones with light blue laser blasts. A few drones tried to strafe Sam, but Beetle brought both hands together to form a large blue and black shield. He flew in front of the shots, arms outstretched, and deflected the enemy fire in time.

"Whoa! Thanks!" Sam said.

Beetle nodded, eyes trained on the remaining drones that had taken evasive action.

His shield morphed into a giant blaster that decimated scores of drones. The Batplane soared nearby, and missiles spiraled off from the jet and annihilated the remaining drones. The jet then veered in a sharp turn with a roar of its engine to prepare another pass.

A ways off, Grodd fought for visibility and breath as the last of the smoke cleared, and Clover saw the helicopter closing in. She shot her Laser Lipstick at the back rotor blade, causing a small fire and plume of smoke to appear. Dyna-Mite struggled with the controls to land.

The chopper spun downwards away from the building and out of sight. Beetle caught sight of it and chased after the helicopter. He formed a large blue mace over a hand and sent it through the side window of the chopper to knock out the villain. The hero grabbed hold of the chopper's fuselage and fired off his jet rockets in reverse to safely guide it down to the street far below, the area surrounded by a few police cars.

Back at the top of the tower, Batman set the autopilot on his jet and leaped from the cockpit to glide towards Owlman. He flung a pair of Batarangs, but the villain tossed his own gold projectiles, similar in appearance to the emblem on his chest. All four weapons collided with each other in midair with a clang. Batman ended his descent and swung a lunging kick at Owlman, who jumped back the moment before it struck. Both stood on the solid, connected top of the iconic W, fists raised.

"This interdimensional escapade ends now, Owlman," Batman said.

With a shout, Owlman swung devastating punches at Batman's head and body. The hero could scarcely keep up with dodging and blocking each of them. Batman stepped backwards, mindful of his limited space, then jumped to the right, off the side of the building, and sprung back with a mighty right cross.

Owlman ducked expertly, but had to defend Batman's follow-up flurry of punches and knee strikes. His thick gold armbands on his forearms gave him extra defense while guarding, and he nimbly lunged into a low sweep kick that Batman jumped over. Batman dashed to grab the cable, then swung it to ensnare Owlman's legs before he could react.

"I won't let you destroy those other Earths," Batman said.

The villain grimaced, shifted his legs to slam the magnetic cable connection to the surface below him, then worked to free himself. Just as Owlman untangled himself, Batman landed a strong left uppercut to stun him. Power flowed up the cable to Grodd's device, causing it to hum and emit white light through the Oscillator.

Owlman staggered a bit from the effect of Batman's blow, but shot a grappling hook up to the observation deck railing, then pulled himself up by retracting the cable. Batman readied his laser cutter to sever the cable, but Owlman tossed an Owlarang from above, striking the gadget. Batman dropped the device off the side of the building, frowned, then used his own grappling hook to reach the deck above to avoid being an easy target.

"You're too late!" Grodd bellowed to Batman, Sam, and Clover. "Now all Earths except the Gorilla Earth will be annihilated," he said with a grin. He tapped on the Oscillator's keypad and a black portal formed nearby for his escape.
