Goku and Vegeta flew to the energy signal. They couldn't wait to meet the two mysterious people. When they reached the signal they found no one there.
"Hello? Is anyone here?" asked Goku. Then Goku and Vegeta sensed something behind them. They turned and saw the two figures.
"What did you call us here for?" asked Vegeta.
"You said you wanted to know who we are. We are giving you the chance to figure that out. We will reveal ourselves if... you beat us in a fight. For now you can just call me Umbra and my friend Lumis." The first one said.
"Believe me you don't want to fight us Umbra." Goku said.
"Well actually we do." Lumis said.
"Then let's get started." Vegeta said as he went super saiyan. Goku went super saiyan as well.
"Before we start answer me this. Are you against us or with us?" Goku asked.
"If you beat us we will explain." Lumis said.
Goku and Vegeta disappeared and reappeared behind the Umbra and Lumis. Goku punched Umbra twice and then kneed his chin. Then he fired a big ki wave at him. It sent him into the side of a tree.
Vegeta was much more forceful with his attack. He punched his opponent ten times and then kicked him into the air. Then he disappeared and reappeared high above him.
"GALIC GUN" he cried. Vegeta unleashed his attack and it slammed Lumis right in the back.
"Well they weren't so tough." Vegeta said. Once those words were spoken Umbra and Lumis flew into the air. Golden energy erupted around them. There powers took a jump. Goku and Vegeta knew they became super saiyans. Their cloaks were still on and they basically looked the same except now they were stronger and had a golden aura.
"So you're saiyans as well." Vegeta said.
"Yes Vegeta." Lumis said.
"How do you know my name?" Vegeta asked.
"You will know all if you beat us." Umbra said.
Umbra and Lumis disappeared and reappeared in front of Goku and Vegeta. Before they attacked they disappeared again. Goku and Vegeta decided it was best to stay away from each other in this fight so they flew away from each other.
Umbra appeared in front of Goku and punched him in the stomach. Goku spit and then recovered. Goku tried to punch Ubra but he caught Goku's fist. He twisted it and then blasted Goku.
Vegeta was blocking Lumis' blows but it was getting hard. He was looking for an opening to attack. Then he saw a hole in Lumis' attack so he kicked him in the chest. It didn't hurt at all so he kicked him again and again with no luck. Lumis disappeared and then reappeared behind Vegeta.
"SAPPHIRE DRAGON FIST" Lumis' fist erupted in blue energy. Vegeta looked back in horror only to have his face collide with Lumis' empowered fist. Vegeta was sent flying into a pillar of rock.
Goku was also on the defensive as Umbra punched him. Goku disappeared and reappeared below Umbra. He was about to attack but Umbra blasted him first. Goku powered up and flew high above Umbra.
"KA-ME-HA-ME-HA" Goku unleashed his mighty wave on Umbra. Umbra stuck out his hand and the blast collided with it. For some reason the blast couldn't pass his hand.
"ENERGY ABSORBTION" Umbra said. At that moment the wave went right into Umbra's hand.
"How did you do that?" Goku said amazed.
"That was nothing. Try this." Umbra disappeared and reappeared above Goku.
"Sadly I can't keep the energy I absorb so I use it well." Umbra said with a smirk on his face.
"What do you meant?" Goku said.
"KA-ME-HA-ME-HA" he cried. Goku's attack came back out of his hand and was headed straight for Goku. It hit him and sent him to the ground causing a big explosion.
Umbra flew over to Lumis.
"I expected more from them." Lumis said.
"I agree. Let's go." Umbra said. When they turned around another explosion went off. Goku and Vegeta emerged in their super saiyan four forms.
"Where do you think you're going?" Goku asked.
"Well it looks like we underestimated you." Lumis said.
"You don't stand a chance. Just tell us everything now if you don't want to get hurt." Vegeta said cracking his knuckles.
"I beg to differ." Umbra said. They began powering up.
"Oh no you can't be serious." Goku said.
A flash of light came and Goku and Vegeta had to shield their eyes. When it died down something was wrong. Goku sensed that Lumis was a super saiyan four but Umbra was different. He still had a golden aura like the rest of them but his power was different yet familiar some how. Vegeta was about to attack but Goku stopped him.
"Umbra what happened to you? You're not a super saiyan four but your power is..." Goku couldn't find the words to describe it.
"Are you confused? Well maybe I'll tell you what I have become later." said Umbra.
Goku and Vegeta went into their fighting stances and so did Umbra and Lumis. Goku was still wondering what happened. This new power was oddly familiar to him but he couldn't remember where he sensed it.
Meanwhile back at home Gohan, Goten and Pan felt something strong.
"What's that?" Pan asked.
"I don't know Pan." Goten said.
"I think we should check it out." Gohan said. They flew out and followed the energy. They ran into Trunks who was following the energy too.
"Do you know what that energy is?" asked Pan.
"I think it's my dad and Goku." Trunks said unsurely.
"What are they doing?" asked Goten.
"I don't know but we better find out." Trunks said as they all went super saiyan too increase their speed.
Goku and Vegeta were having a really hard time with Umbra and Lumis. It seemed their power highly exceeded Goku and Vegeta's.
Lumis sent a volley of punches at Vegeta. Each of them collided with his face. Then Lumis kicked him in the stomach followed by three ki blasts to his chest.
Goku punched Umbra's chest with no luck. Then Umbra kneed Goku's stomach followed by a powerful punch to his cheek. Umbra backed up and then put his hands together and fired and enormous blast at Goku. It hit him hard and it sent him to the ground. Umbra blasted the rubble to add more damage to Goku's already unbelievable damage.
Vegeta kicked Lumis furiously but missed each time. He fired five ki blasts that Lumis just deflected. Lumis punched Vegeta in the stomach. Vegeta spat out blood and a lot of it. Lumis kept punching him and more blood came out until Vegeta could barely keep in the air.
"Let's finish them Umbra." Lumis said.
Goku and Vegeta were to weak to move so they just fell to the ground.
"SAIYAN DEATH BALL" said Lumis.
"EMERALD SKY BALL" said Umbra.
The two giant attacks were fired and Goku and Vegeta couldn't stop them. Right before the two attacks hit Goku and Vegeta two figures flew in and took the attacks for them and saved the two saiyans.
"PAN" cried Umbra.
"TRUNKS" cried Lumis.
