Reincarnated as a Saiyan with a System

Goku stood outside dressed in girl clothes with his hair covered by a scarf. It was noon and Oolong should be coming soon.

Oolong came in the form of a giant demon and talked with Goku, he thought the 'girl' was scared so he turned into a gentleman.

Bulma saw Oolong's new transformation and was still shocked but didn't go out like in the original story.

Then Goku started peeing on a tree, Oolong surprised by a 'girl' peeing in public checked out what was going on and saw Goku's thing.

"GEEEYAAAH, I SAW IT,!" Oolong shouted in shock. He then said angrily, "You, how dare you try to deceive the great and terrible Oolong!?!"

"Wow, you figured that without a pat-pat, your good," Goku said surprised and Oolong who was fuming mad, then transformed into a giant bull to scare Goku.

"Woah cool, a free meal!" Said Tarro, suddenly walking out of the house and materializing a giant meat cleaver.

"Hieee!" Oolong shouted out in fright upon seeing the knife as big as a door being waved around effortlessly by Tarro. He then said, "Y-You I'll crush you to pieces, you puny human," while trying to act tough.

"Oh yeah, you do look yummy!" Goku agreed and licked his lips.

"Do you really think you can beat me?" Oolong continued his acting.

"Hmm, I wonder what will happen when I cut a piece of you off, will it be beef or will it turn into pork?" Tarro said with a grin as he walked closer.

*Swoosh...Crack!!!* Tarro lept at the bull and swung the knife at it, but he dodged and when it hit it cracked the floor.

"Hiiiee! Retreat!" Oolong said, getting scared.

*Poof* He transformed into a bat and took to the sky and Goku jumped on his Flying Nimbus and started chased him.

'This will take a while, so I'll give him a hand,' Tarro thought.

Tarro picked up a piece of stone and threw it at the bat. And *Blam* the stone hit Oolong and he was knocked out.

"Wow, that was amazing!" Bulma exclaimed.

"Wow, you knocked him out with a stone from so far!" Goku said while flying back with the untransformed piggy.

...

After being rewarded the Dragon Ball and saying goodbye to the villagers Bulma brought Oolong with them and the 4 of them rode across the river on a motorboat. It was cramped with the 4 of them and since Tarro did not want to squeeze in the back seat with Oolong and Goku, he sat on the front seat with Bulma sitting shyly on his lap driving the boat. She had easily agreed to sit on Tarro's lap after acting shy and blushing for a few moments.

They were taking the river route since only Goku could ride the Nimbus as the others did not have pure hearts. And the cloud was too small to fit the 4 of them, not to mention they did not know that Tarro also had a Flying Nimbus.

"Why do I have to come along?" Oolong asked.

"Because your transformation can come in handy," Bulma said.

"No way I don't do quests they're boring," Oolong complained.

"Ah, it's so hot, maybe I'll sleep in only my underwear tonight," Bulma said.

"Ah, I guess they don't have to be boring," Oolong happily said.

*Pat Pat Pat* Goku patted Oolong's crotch.

"What are you doing, that's disgusting!" Oolong shouted angrily.

"You're a guy, right?" Goku said, grinning innocently.

"Darn right I'm a guy, and I don't want any other guy touching me ever, okay," Oolong said still mad, while Tarro started laughing again.

...

In the desert, Goku and Tarro walked ahead. They were passing through the Diablo Desert.

"Oolong why are you so slow!" Goku turned around and complained.

"Tch, it would be easier if you carried me like Bulma is!" Oolong complained exhaustedly and mumbled, "I lost all my strength from diarrhoea."

Bulma was really weak and couldn't even stand on her own anymore, Tarro kindly carried her on his back as he had offered earlier.

"Yeesh, I never thought there was this much desert," Bulma complained while sitting on Tarro's back.

"It can't be helped. We can't get to Mount Frypan without going through here," Oolong said, exhausted.

"Do you think there's a hotel or inn around here?" Bulma asked.

"There's no way there is any!" Oolong said.

"No! I'm not doing this anymore!" Bulma complained while waving her arms about.

"I'm hungry! I want a bath! I can't sleep without a bed!" Bulma shouted throwing a tantrum.

Tarro was about to take out a Capsule filled with food for Bulma to eat, but she fell asleep while being carried.

When they were just about to meet Yamcha, Tarro brought out some food and shared it with Goku and since Bulma was asleep, and Oolong was hiding his motorhome capsule, Tarro didn't give them any food.

Then Yamcha came riding on his speeder to rob them, but since Goku wasn't hungry he easily defeated Yamcha. After Tarro refused to give him food, Oolong reluctantly revealed his motorhome capsule. When Bulma woke up inside the motorhome she was happy but upon learning where the motorhome came from she got angry at Oolong. Bulma had also not been as infatuated with Yamcha as she had been in the original, for some reason.

Tarro and Goku practically cleaned out Oolong's motorhome's storage of food. Then, like in the original story, Yamcha snuck next to the motorhome and overheard Goku and Oolong's conversation about the Dragon Balls. Upon learning that any wish was possible, Yamcha decided to steal the dragon balls to wish for his fear of women to disappear. Because Yamcha knew he was not a match for Goku, he did not fire a rocket at their motorhome and destroy it and instead put a tracker on it and sneakily tailed them from afar, since they already had 5 balls, it won't be long before the group manages to gather them all.
