It was a normal day in the space-time continuum for Professor Prestige. He's the one-of-a-kind scientist, monitoring the space-time continuum to ensure peace and balance in the universe. Not just any regular universe, though. He could monitor every single universe in the multiverse.

However, he had a strange feeling that something large and bad was going to happen, so he investigated this strange distortion.

"Hmm...nope...nu-uh..." the professor said as he went through universe by universe, looking at his Pocket Pad, in which he used to moniter the universes and manage from there.

"Ah-ha!" the professor exclaimed as he found the distorted universe. It appeared to be, coincidentally, a My Little Pony universe, in the Friendship is Magic world. The Professor decided to find out what was causing the distortion, so he travelled to the universe in his "Box of Wonders".

When he arrived at the distorted world, he saw what appeared to him as a peaceful land, filled with a pony population around the land. However, he saw impending danger of what appeared to be mindless zombie-like humans, controlled by a fiery-looking female gargoyle controlling the horde, along with two smaller male companions as her sidekicks.

"This is bad," the Prof thought to himself. "Very bad. I'm really gonna need some help with dispelling this great evil and restoring peace and balance to this world, and the multiverse."

With that, he set forth, looking for help to dispel the great evil upon the land.

The Prof himself looked through multiple universes through his pad, hoping to find suitable candidates for the job. As he read the name of the world, he also wanted the candidates to band up together as friends to promote the magic of friendship around the multiverse.

After looking through multiple fandoms and universes, he had found one particular universe that could help him and the multiverse altogether. The Grand Theft Auto universe. Consisting of multiple protagonists, the Prof wanted to get the guys together, so he set forth for his next stop: Liberty City, in 2001.

Meanwhile, in the GTA universe...

Claude Speed, after having put down Catalina, his ex-girlfriend, for betraying him and left him for dead, and dropping off his current girlfriend, Maria, was taking a drive around the streets of Staunton Island in his newly jacked Stinger, when a strange, bright light, appeared in front of him, out of nowhere. He stopped his car, and got out, preparing his AK47 just in case. Meanwhile, nearby pedestrians ran away from the blinding light that showed up from nowhere. Claude covered his eyes slightly as he heard a voice from the light.

"Come with me, friend. I have a job for you to do," the voice said to Claude.

With nothing else in consideration to do in Liberty City, Claude walked toward the light.

As soon as he stepped a few feet from the light, in an instant, it vanished, taking Claude along with it.

Tommy Vercetti, just after killing Sonny Forelli, who had set him up a long time ago, along with Lance Vance, who betrayed Tommy at the last minute, was sitting in his office in his mansion, located on Starfish Island. He was discussing things with Ken Rosenburg, his lawyer.

"Okay, Tommy, there's still lots of things here for us to clean up," Ken began. "We got the Print Works, the Malibu Club, the Kaufman Cabs depot..."

"Shut it, Ken," Tommy responded. "Relax. There's still lots of improvement for property development here in Vice City. We just need to..."

Suddenly, the conversation was interrupted by one of Tommy's gang storming into his office.

"Boss, we've got trouble, on the roof," the gang member said to Tommy.

"What is it?" Tommy asked.

"There seems to be some weird-looking light just upstairs, Boss."

"I'll handle this," Tommy said as he dismissed the gang member. He grabbed his M4 from the office table of his, and went up to the roof.

When Tommy arrived onto the rooftop, he saw some of his gang backing up from the strange light, aiming their Colt .45s and Micro Uzis at the light, just in case. Just then, a voice was heard.

"Tommy, I need you on a particular job to be completed," the voice said.

"Wait, what job? And why should I care?" Tommy asked.

"It depends on the fate of the multiverse! And if you don't intervene, all the universes, even your world, will soon be no more! Just step through the light, and all will be answered!" the voice answered.

With no other choice upon hearing the news, Tommy decided to take the job. He stepped into the light, and he disappeared, just before his gang's eyes as the light vanished.
