I appear just in time to see Moro beating Vegeta up. Vegeta is not in his SSB yet. Right now he is only using SSG to fight Moro while Moro is using the energy of the planet to fight back. After Vegeta confirms that Moro is as bad as the Galactic Patrol made him out to be, Vegeta turns SSB to finish Moro off.
"Y-you… were concealing your strength?" Moro
"Like you were hiding your true intent?" Vegeta said cockily.
That made Moro angry so he summons as much energy from the planet as he can and use it to attack Vegeta. Vegeta easily dodges the attacks and kick Moro hard into a lake nearby. When he did so, I look around. I can see the leaves falling off of the trees nearby as they die from having their life energy absorb. A second later, Moro flies out of the water.
"I don't care what sort of Villain you are but I won't stand by while this planet suffer." Vegeta
Goku can also see the trees dying so he yells out to Vegeta "Keep your guard up Vegeta, something weird is happening."
Moro took the chance while Vegeta is distracted by Goku to fire a Ki blast at the ground creating a smoke screen for him to escape to a nearby hill. Moro than gather as much energy as he can into a ball. After the smoke clear Vegeta can see Moro holding a big ball of energy.
"Make that as big as you want, it's useless against me." Vegeta
Moro just smiles before shrinking the ball and eats it.
"What?!" "He ate it?!" both Goku and Vegeta were surprised.
After eating the energy, Moro appears a little younger and his Ki explode out. Everyone can feel that he is stronger than before.
"So that's how you go around absorbing energy. That's why Merus want to capture you quickly. Why don't we hurry up and settle this." Vegeta
"Oh? Try me if you can." Moro
"You think that little boost is enough to suppress us? SSB is way beyond your power." Vegeta said as he easily turns back into SSB.
"WHAT!? How did you transform? You shouldn't have enough energy to do so after I absorb it." Moro said surprise since his magic is supposed to absorb the planets life force along with anything on it.
"So it's true that you can also absorb our energy." Vegeta
I choose this time to cut in. I appear behind Moro when he is distracted and put a magic seal on him. From what I understand about the seal, it can prevent a person from getting their energy absorbed but you can also make it so a person can't absorb or control energy outside of their own. I kick Moro toward Vegeta and Goku.
"Who are you!" Moro said after he got up
"I'm Ken, your worst Nightmare."
"Worst nightmare, what a laugh. I have seen people scarier than you." Moro
"Ken, why are you cutting into my fight." Vegeta
"Relax Vegeta, I'm just making sure he can't absorb any more energy."
After Moro heard me, he tries to gather more energy from the planet only to fail.
"What did you do to me!?" Moro
"Easy, I seal your power. Unlike the Grand Supreme Kai, I can easily do it without any sacrifice."
"YOU!!" Moro said angrily as he jumps to attack me. Vegeta intercepts and kicks him away.
"Your opponent is me." Vegeta
"Find. I guess I'll just have to get rid of you first." Moro
Moro went to attack Vegeta again. This time, Moro is more evenly match with Vegeta using the energy he absorbs but we can see that Moro is on the losing end. Even Vegeta hasn't gone all out in his SSB yet.
Vegeta keeps beating Moro but it doesn't look like Moro is taking any damage. As the fight goes on, Vegeta got more tired while Moro is still fighting at his full power. Having enough of it Vegeta use is full SSB power and starts beating Moro up without giving him any time to fight back.
"WHY. WON'T. YOU. STAY. DOWN!" Vegeta said every time he punches Moro. He finishes off with a Ki blast that knocks Moro into the side of a mountain.
"HAHAHAHA!" Moro laughs as he got out of the mountain looking unharmed. "You won't be able to defeat me. To defeat me you'll need to hit me with a power strong enough to wipe out all the life energy I absorb throughout my life."
"Fine then, I'll do just that!" Vegeta declared as he stands in a T pose. He gathered up his energy on both hands before bringing it together in a massive Ki blast that uses all his energy. "FINAL FLASH" Vegeta yells as he fires the Ki.
Moro senses the danger of the Ki blast and tries to escape but the Ki blast is too fast and consumes him in less than a nanosecond. After the Ki blast ended, we can see that it didn't finish off Moro. he is still standing even though he looks even older and more tired than before we met him.
"Hahaha, is that everything you got. In that case. DIE!!!" Moro yells as he charges to attack Vegeta. Vegeta didn't think Moro would survive the attack so he wasn't prepared for a counter attack. Added to the fact that Vegeta is currently low on energy, he couldn't dodge and got sent flying.
I quickly appear behind Vegeta and stop him in midair while healing him and giving him some energy.
"My turn!" Goku calls out as he charges at Moro.
"Hey!" Vegeta yells "I'm not done yet." He tries to go back and join the fight but I stop him.
"Too late now. You are currently out of energy and won't have enough to transform. Without it you won't be a match for the current Moro."
"Tsk." Vegeta click his tongue and went to watch Goku fight Moro instead.
The fight between Goku and Moro is really one sided as Moro is still trying to recover from the attack by Vegeta. Goku in SSG is able to beat the current Moro without too much effort.
"This is boring," Goku said as he punch Moro into a mountain again. "Looks like Vegeta tire you out too much it's not fun at all." Goku turns his attention to us. "Hey Ken, can you remove whatever you did to him. It'll be more fun that way."
"No way Goku. He's far too dangerous to do so. If you want a fun fight wait until Vegeta recover or go find Beerus."
"Aww but.." Goku
"No but."
"Fine, I'm done here. You can do what you want with him." Goku said as he lost interest in the fight.
"I guess I'll take Moro than."
"TAKE ME! IF YOU THINK THIS IS ALL I HAVE, YOU ARE MISTAKEN!" Moro said as he starts to gather more energy.
"Nope." I instantly appear behind Moro and knock him out using the Galactic Patrol gun I still haven't given back to Merus yet. The reason I can knock him out with the gun is because I enchant the gun to break through Moro's magic while he was fighting everyone. I think I'm going to keep the gun if Merus is not going to ask for it
"And with that, it's over." I grab Moro and make my way toward Goku and Vegeta. "You two can go back to Earth and tell the Namekians that it's ok to return now."
"The Namekians are on Earth?" Goku
"Yeah, I use Shenron to teleport them to Earth earlier so they don't get caught up in the fight."
"Oh, that's smart. I'll be taking the news to them than. Vegeta you coming?" Goku said as he puts his finger on his forehead. Vegeta didn't answer and just grumply puts his hand on Goku shoulder.
