Two Immortals fighting

Zephyr disappeared and landed back on Earth. He hid and modified the uniform slightly… The folded over part was shortened, the sash was lengthened, the pants were less puffy and tucked into the boots that were rounded with black tips.

He changed the Gold Bracelets and fused one with his Watch, modifying his Potara earrings before letting out a breath of relief, running his hand through his hair, "Okay, much better."

He popped over and hovered in the sky before flashing, "Damn! Am I late?!" Bulma looked at him, "Oh! What happened to you?!" Zephyr rubbed his head and sighed, "I spent a 100 years getting abused…" Launch looked over and wiped her drool, "Hehehehe~ Come home quickly…"

Bulma pointed at the Time Machine, "Go, quick!" Zephyr winked at Launch before teleporting inside the Time Machine, "Hey." Goku and Vegeta looked at him, "What the hell?!" Zephyr rubbed his head, "Haha… So what happened was…"

The Time Machine disappeared.

It reappeared in a ruined city as they jumped out, "So you were training for 100 years?! Damn it!" Zephyr spread his hands and sighed, "I didn't actually. 50 years of weakening, 50 years of training back from nothing. It's more optimized now… like, uh, how do I explain it… No wasted movements!"

Vegeta punched at Zephyr, who turned to Goku, "Do you know where Zamasu is?" while dodging Vegeta's punch. Vegeta clicked his tongue, "I haven't been sitting around doing nothing either!" Goku waved, "We have to settle Goku Black and Zamasu right now, you guys!"

Zephyr and Vegeta nodded as the three flew away, they teleported in the air, appearing above Zamasu and Goku Black, who held Future Trunks. Goku Black dropped Trunks and sneered, "What took you guys so long?"

Zamasu looked at Zephyr and frowned, "Who are you? A Human in a Kai uniform?!" Zephyr turned and looked at him flatly, "Boo." Zamasu's eyes widened and he blasted off the ground, smashing through several dozen buildings, landing in rubble.

Zephyr turned back and said, "Give Gowasu a Senzu Bean!" Goku nodded, "Right!" as he fed Gowasu and Trunks, picking them up. 

Mai ran over, "Trunks!" Zephyr looked at her and sighed, pointing at Mai's head, "Don't move." Mai started sweating, "Oh shit!" Zephyr rolled his eyes, "Please! I'm not going to kill you!"

A beam pierced into Mai's heart and she froze, "Ugh!" before a powerful heartbeat sounded. Her hands frosted over before she exploded into an ice sculpture. The ice shattered and Zephyr snapped his fingers, giving her new clothes as she looked brand new.

He muttered, "These Kai powers sure are convenient… They also work suspiciously well with the System… Hmm…" Mai looked at herself in shock, "Huh?!" Zephyr explained, "I gave you Ice Powers. Now you're not helplessly hiding behind Trunks everyday… The more you practice the stronger you can become. Hopefully one day, you can protect HIM. Get it?"

Mai burst into tears and jumped up, hugging Zephyr, "Thank you! Waaaah~!" Zephyr shook her off him, "DON'T RUIN MY CLOTHES! DAMN IT!" 

Goku laughed and shook his head, "Alright you two alright?" Gowasu and Trunks nodded as Gowasu got up, looking at Zephyr, who was pushing away Mai's crying face, "He's not a Kai… That's the same young man that visited me a few days ago?"

Goku was stunned, "You know Zephyr?" Gowasu nodded and sighed, "He killed my evil Disciple." Goku nodded and patted his shoulder, "Don't worry, Universe 10 Supreme Kai. You'll find a new one, Zephyr is training with the Supreme Time Kai." Gowasu was terrified, "That devil?!"

Zephyr appeared next to him, "You really understand me, Old man! She's really a devil! I was beaten senseless for 100 years!" he even shed a tear as Gowasu sighed, patting his shoulder, "There there… Poor thing…" Shin scratched his head, "Well, what are you going to do now, become the Supreme Kai?"

Zephyr rubbed his nose, "Huh? Maybe in a million years or something, right? Vegeta has to train with Beerus." Shin let out a breath, "Phew!" Zephyr rolled his eyes, "I don't want your job… If I didn't have to take it, who would want it??" Shin froze and twitched, "Well…"

Zamasu flew back, "Impossible! A Human becoming a Supreme Kai?! You aren't even a Kai! Unbelievable! I don't agree!" Goku stomped on Zamasu, sending him flying as he grinned, "Dibs!"

Zephyr was dumbfounded, "No! Wait! Asshole!" as he flew after Goku angrily. The others were stunned… Gowasu looked at Shin, "I've never seen a Supreme Kai who wants to fight all the time…" Shin laughed awkwardly, "Our 7th Universe is very… special… Supreme Kai of the 10th." Gowasu smiled cheerily, "Well that's nice. By the way, would you like to be my disciple?"

Shin's lips twitched.

Goku tried to seal Zamasu with the Mafuuba but he brought the wrong Talisman and Zamasu escaped. Goku sighed, "Aw man!" before going SSG and beating Zamasu senseless.

Zephyr touched down next to Goku and Vegeta as they watched Zamasu and Goku Black argue with each other before fusing into Zamasu Black, but Zephyr preferred to call him Zamasu…

Zephyr said, "Damn you, Zamasu!" Vegeta looked at him, "Zamasu still?!" Zephyr looked serious, "I will not inflate the word count!" Vegeta clicked his tongue angrily.

Zamasu sneered as he held out his hands like Gojo, "Rejoice mortals… For it is an honor to behold this form. The one true God of all Universes… Zamasu, is finally born!" Zephyr dusted his palms, "My turn!" as he flickered, standing in the same place.

Zamasu threw up blood, "WHAT?!" before taking out a box and putting on a Time Ring. Zephyr frowned, "A Time Ring?" Zamasu sneered, "You just attacked my past didn't you? By 5 minutes behind. Before I fused!" he showed the Time Ring box, "But with the Time Ring, I'm unaffected by Time Based attacks!"

Zephyr flashed and held the Time Ring box, "Oh~" Zamasu was stunned and Zephyr rolled his eyes, "Idiot. Do you think I'm like you? I trained hard to get where I am! I can move fast enough affect time, I don't use props!" he took out the other 5 Time Rings in the box, "But! These are useful."

He crushed the Box as Zamasu snorted, "You have no chance anymore. I am a Supreme Being!" Zephyr took out a Fusion Token, melting the Time Rings into his left golden bracelet.

A white infinity symbol appeared on the underside of the bracelet as Zephyr waved his arms, "Alright, cool."

Vegeta and Goku shouted from the side, "Hurry up and start fighting! We're waiting here!" Zephyr rolled his eyes at them, "I'm gonna start! You can't interfere!" They both nodded helplessly, eating Senzu Beans mixed with Eternal Youth pills. 

They just ate them like Jellybeans.

Zephyr rolled his eyes and looked at Zamasu, rubbing his shoulder, "Alright, come on. After I beat the shit out of you, I'm going to visit my Master in this timeline. I heard she was a big beauty here." he was slammed into the ground before getting up like nothing happened.

Zamasu frowned, "Master?" Zephyr took a stance, handing his hand positions and leaving two knuckles out, smirking.
