Prologue

"Go, Team Go!" a booming voice commanded, breaking the still air in the normally quiet Go Park. A rather tall and muscular blue-haired man called out to his teammates as he charged toward yet another nemesis vowing revenge against them. The strongman, Hego, attacked from the north while his twin brothers, Wego, each multiplied tenfold and darted in from the west and east. His third brother, Mego, wielding a staff, hurtled toward their foe from the south.

"You'll never catch me, Team Go!" declared their opponent, the villainous Officena, who took pleasure in using office supplies as weapons against her enemies. Cackling, the self-proclaimed "clerical mistress" did not seem to mind being surrounded—she took out two staplers and shot out rounds of sharp staples all around her.

"Ack! She had to use half-inch staples, didn't she?" Mego lamented as he dodged staples left and right, eventually able to shrink to a size small enough to find safety inside a small hole in the dirt ground.

Continuing her onslaught, Officena hurled numerous 12-inch rulers at Hego like daggers, one of them managing to strike him squarely between the eyes and knocking him conscious.

"Hego!" the Wego twins cried. Angered, they rushed head-first toward Officena, only to run onto a pool of super-sticky glue poured from a seemingly bottomless bucket by the crafty criminal, bringing Wego and their duplicates to a standstill. "Hey!" they exclaimed, falling to the ground as they struggled to break free.

"Ha, ha, ha! Twenty for the price of one, what a deal!" Officena taunted. "Hmm," she said with a somewhat musical lilt to her voice, "there's someone missing here. Oh Meeego, where are you? You can't hide forever."

"This…is not good," the still-shrunken Mego said to himself, breathing heavily. "Come on, Mego, think of something. Come on, come on," he repeated, hoping that a strategy would come to mind quickly.

Officena, however, would not give the last standing member of Team Go much time to come up with a plan. "Perhaps a good bath in correction fluid will draw you out," she sneered. With that, she held another bucket and poured out a torrent of white correction fluid, threatening to drown the small hero. Panicking, Mego had no choice but to enlarge himself back to his normal size. No sooner did he grow back than Officena shot out streams of adhesive tape which wrapped tightly around Mego's body. "Oh, this is so not good," he said, unable to escape.

With the opportunity to get rid of Team Go, Officena took out a laser pointer, and with a sinister smile, aimed it at Mego. "The laser in this pointer can burn much more than the eyes. Trust me, you'll go down in a blaze of glory. Literally." Mego gulped as Officena prepared to fire. "Now I will finally get rid of you and your meddling family once and for all!" she said as she pressed the pointer button and fired. However, nothing came out of the pointer. Shocked by the pointer's failure at her first attempt, Officena pressed the button several more times, but to no avail. "What is this?!" Officena exclaimed. Initially startled as well, Mego regained his calm and, seizing this lucky break, grew in size, easily breaking free of the adhesive tape. Towering over Officena, Mego snatched the felon and wrapped his hand around her so tightly she could not move.

"Aagh!" Officena screeched. "My weapons never fail me! How could this be?"

Mego smirked and replied with sarcasm, "Dead batteries?"

Having regained consciousness, Hego freed the Wegos, and together they ran to where their brother and his captive. "Good job, Wego," Hego said then looked up at their nemesis. "Looks like you've been clipped, Officena," he remarked. "It's back to the cooler for you, and I don't mean the water cooler."

As was the routine, Mego and the Wego twins rolled their eyes and groaned at Hego's dreadful use of puns.

Back at Go Tower…

As Wego ran off to play video games, Hego and Mego sat back and relaxed in the mission control room. "I don't get it," Mego said. "Why didn't Officena's laser work? It's not like she's a total slacker, especially with those gadget things of hers."

"Indeed," Hego agreed. "She is one of our most meticulous foes, and for her to neglect any of her weapons, be they for batteries or otherwise, is strange. I wonder…"

As Hego speculated on what could have caused the serendipitous "glitch" in their battle today, the Go communication screen beeped. "Look," Mego noted, pointing out the security screen showing the tower's front entrance. "Someone's paying us a visit."

Having heard the loud beeps, the curious Wego twins ran to meet their brothers in the control room. "Who is it?" they asked in unison.

Furrowing his brow in apprehension, Hego warned, "Be prepared, brothers. This could be a scheme by another one of our foes."

"Yeeeah, just answer the call, big guy," an impatient Mego responded.

Hego pressed a button to open the communication line, and to everyone's shock, the person on the other side was not one of their enemies. In fact, it was someone they hadn't seen in more than a decade. Someone they had never expected would voluntarily come and visit them…

"Igo?" Team Go spoke simultaneously.

"Hey, boys, long time no see" said the woman on the screen. She was amused to see the stunned look on the men's faces, their mouths agape. "Planning on letting me in sometime this decade?" she teased, snapping the team back to reality.

Moments later, the four heroes of Team Go were face to face with a ghost from their past. Though it had been many years since they last saw Igo, her appearance had not changed too drastically, from her long and curly flaming orange hair to her pale orange skin. Her cheeks still revealed the tiny freckles she had the last time they saw her—when she was only fifteen—though they seemed to have faded a bit since then. Still in shock, the team could not believe their cousin would return after all this time. After all, she was the one who left them with sour apples not long after—that fateful day…

"You're hair's grown," Mego meekly started, clumsily breaking the thick blanket of silence that had filled the room for several minutes.

Igo grinned at her usually overconfident cousin. "I do like it long, but with the hot weather, it may be time to get a haircut."

"Enough with the small talk, Igo. Why are you here?" Hego demanded suspiciously.

"Always were the one to get down to business, eh, coz?" she smirked.

"I doubt you'd come all the way here, after all these years, just to catch up on old times, Igo. That doesn't seem much like you," Hego maintained.

Igo smiled, "On point, as usual, Hego. I did come here to take care of some business."

"And what business is that?" Hego asked pointedly.

With a serious expression on her face, Igo simply replied, "To bring Team Go back to greatness."
