The time I was fused with my cat and sent into the Dragon Ball world

Galactic Patrol, New Recruit

For the next 2 years, I perfect Spirit Control on Yardrat with Princess Snake under Pybara, learning how to use every technique of the Yardrat. I'm well aware of the future events, but know how Fu is going to make things drastically different. I've been sensing energies that aren't supposed to be from this universe, yet they feel like they are. A fluctuating power on a distant planet in another galaxy, a Saiyan planting trees, and a vengeful Tuffle Scientist. Right on cue, I feel something else. Someone descending into the planet, landing. I open my eyes, raising up in base into the air, wearing my Yardrat attire. Teleporting to the energy as it returns to being undetectable, I see who it is, and go pale for a moment. "M-Merus?" I question, stuttering and becoming nervous as he steps off a Galactic Patrol ship. "I'm not ready to leave yet, Merus, please. I want to help this universe. I want to fix my life, and I feel I have more to do. I'll even join the Galactic Patrol if I have to, if it means I'll be able to stay!" Merus is quiet for a moment, but then smiles, chuckling in amusement for a moment, then stopping.
"I'm not here to send you home, don't worry, William. I've been aware of you the entire time, and so is my brother and father. We're happy with your progress, and don't plan on sending you back to your universe against your will." Merus replies, calm and collected. "I'm actually here to recruit you into the Galactic Patrol, but since you're offering, come with me." I look at the Yardrat people, smiling.
"Master Pybara, everyone, thank you for training me. My journey has just begun, however. There's many threats out there I have yet to face. Threats I can't ignore." I tell the population gathered in thanks, bowing respectfully. Pybara nods and bows in return, and I turn back to Merus, who's currently waiting in the ship. I walk over, stepping into the ship and watching the door close. Sitting down next to Merus, I watch as Yardrat disappears from my sight slowly.

2 Months Later...

"Very good, recruit William! Exceptional scores as usual." The instructor tells me as I bow in respect, acknowledging how my progress is allowing me to grow exceptionally. I've mixed the Galactic Patrol uniform with the Yardrat clothes, adding the Turtle School symbol next to the symbol on the Galactic Patrol chest piece, carrying a piece of each of my masters in my clothes. It's respected, so they don't make me change it. Someone appears moments later with the sound of instant transmission. Someone I recognise.
"I guess you're here, my future self." I comment, turning to look at him. He meets my gaze with a steel sharp expression, and I know why he's here. "You never got a chance at joining the Galactic Patrol, but I did. Plus, Fu knew about your visit! Read my mind and see for yourself!" My future self sighs.
"Very well." He responds, cold and calm.  I watch his expression quickly turn to shock. "...What? Cooler? Z Broly? Turles? Hatchiyack? This is bad, you made a good call in joining the Patrol." My future self turns to the instructor, sharing the information, and he calms down and accepts my future self being here. He nods and leaves the room, going to report the results of my training for the week to Merus. I look at my future self, calm.
"I awakened the power and am working on perfecting it. It works how Dragons Ball AFs Super Saiyan 5 does, the version with new Shadow Dragons. The one by Young Jijii." I inform my future self, calm and focused. My future self nods in acknowledgement.
"Right. I noticed it, but I knew you'd figure it out. That's why I didn't tell you." He responds, knowing I was going to figure it out as he smirks.
"I'll be able to handle things here. WE will be able to." I reply in confidence, calm and ready to help the universe. As he teleports away, I leave the room and hit the showers. In the shower, as the water washes over my body, I look in the shower room mirror with a smile.
"Damn, I look good." I continue showering with that remark to myself, calm. After the shower, I get back into my clothes and head to where the ships are, knowing the mission is today. The pursuit of Turles is the first mission he's being assigned that's high priority, as he personally requested to be the one to fight Turles and his Crusher Corps. Arriving after a few minutes of walking, I get into my assigned ship, putting in the co-ordinates for where Turles will go next and taking off as the ship door closes.

"This is Agent William, departing for mission now."
"Loud and clear, good luck Agent." Merus responds from the other end of the communiation line as I blast off into the stars.
