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

King Kai training, Snake-Cat Hybrid Born.

After what happened, me and Princess Snake sit in bed together, worried. What we did is something we know we shouldn't have. I'm alive, and she lives in Otherworld. "I'm willing to commit to this, but I can't help but worry. How will the child grow, being a triple hybrid in a way?" I ask Princess Snake, having made her aware of my origins. She looks at me with joy and concern in the same expression.
"We'll face this together, I'm willing to commit too. For now, you should freshen up and continue on to King Kai's planet. You'll have to beat them if you want to make a safe world for our kid." She tells me, genuinely wanting to make sure the world beyond is safe, hinting at a possible move to the living world with her servants. I smile and nod, going to the Hotspring, freshening up. My body takes in the hot water, allowing me to clean up. As I clean myself up, I wonder how much I'm going to get out of training. What could King Kai teach me? As I come out eventually and dry off, getting dressed into a cleaned version of my gi, I let myself think about other things. What me and Princess Snake did, we went too far. As long as we're willing to try though, it doesn't matter. I've already gone through the confusing and meticulous legal process because of my origins, and I'm legally a citizen in this world now. Working at a pet store works perfectly for me, as long as I maintain my multiform over there. Luckily, it's self-sustaining, so I can support a wife and child. I wave goodbye to the servants, hugging Princess Snake. I'm then sucked out of the building the same way I came, landing smack dab on the floor outside.
"...Ow. Anyway, King Kai." I remind myself, getting back up and continuing my sprint. I notice Goku is behind me, so I decide to do something. I sprint ahead, making a challenge to Goku without even talking. I sense him speed up at full power, then I do the same. I completely outpace him, making it to King Kai in minutes. The gravity weighs me down by a massive amount. Luckily, I have the Senzu Beans with me still. As I stomp around the planet, I eventually find a small blue man, wearing clothing with the Kanji for 'Kai'. "Are you...King Kai?" I ask, straining because of the gravity, but adjusting quickly. The man nods, taking things very casually, which annoys me.
"I am King Kai, the North Kai. Since you're here by request, you don't need to come up with a joke for me. Your fused body will be able to handle this training, much more than any normal humans." He admits to me, giving me a chance to calm down. Over the next months, I train. Goku in time arrives, starting from where I began. I don't find the joke he comes up with funny, to the chagrin of King Kai. "You could laugh, you know. You don't have much of a sense of humor, do you?" King Kai questions, somewhat irritated.
"King Kai, I'm trying to train for an alien invasion, learning how to use the Kaioken, speeding trough my training, having to check in on Princess Snake and her pregnancy, all in the same year period. I have no time for jokes. Besides, I prefer dark humor in Cards Against Humanity." I reply, very much serious about my training. King Kai is...surprised.
"Wait, Princess Snake is pregnant? You're the father?" He questions, surprised and confused. I give him a very knowing look, confirming without words that I am the father. He becomes panicked for a moment, but realises my plan and calms down. He simply nods in acknowledgement. "Congrats on the coming child."
"Thanks." I reply, glad that he's approving my relationship with Princess Snake. I watch as Goku learns the Kaioken and Spirit Bomb, myself unable to do the Spirit Bomb. I remember the principles of the technique, though...for a later purpose involving Yardrat. 3 days before the Saiyans arrive, I take off from King Kai's planet without telling anyone. I can handle the Saiyans now just fine. I feel it. I stop by Princess Snakes Palace and...there's a note there. It reads: "Waiting at your place, dear."-Princess Snake. I realise what this means, using Kaioken to get a speed boost. Arriving at the check-in station, I grab Kami and he teleports me to the Lookout on earth. I then blast off home, landing outside and...smiling. I see her. Princess Snake. She holds a small boy with Snake Eyes and a Cat tail. I walk over, powering down from Kaioken and hugging her, holding the boy in my arms. He looks up at me. "Hello, little one...I'm your papa." I quietly tell the baby. He seems to subconsciously recognise that. I lean in as he reaches for my face. I let him bap my face, exploring it. "He's adorable dear, what'd you name him?" I look at Princess Snake. She smiles back.
"Gato. It means cat in another language from your world, I believe." She responds, looking at Baby Gato with love. I smile and nod. The baby falls asleep in my arms, and I carry him inside with Princess Snake. Someone to protect. Someone to fight for. A child to love and protect. Light blue skin, orange cat tail, Snake eyes. A precious baby boy. MY baby boy.
