A/N: Gotta say, I thought the DBZ fan-base was slowly dying out. But I guess I was wrong on so many levels. The amount of support for this story is quite staggering it I'm being honest, and I can say that I'm more than happy about it.

With a decent amount of action in the last chapter, I figured a little backstory was in order. And even though not everything will be explained, it'll give my readers a chance to see more into 'Cooler's' past and what may drive him to do what he does and what led him to Earth.

Time to start shaking things up a bit!

"As grateful as we are for your assistance, it still leaves the question of why you are here." said the Earth's Guardian.

Cooler was silent for a moment, "Before I go into any details, I think its best if the Earth's defenders are all here. I'd prefer not to repeat myself too much, to be honest."

"And what is so important that everyone has to be here?" asked Piccolo skeptically and still untrusting of their guest.

The oldest son of the Cold family turned to the Namekian fighter with a serious expression. "How about information that my revenge-fueled little brother is still alive?" That statement caused all the air to vanish in the immediate area for those who had fought the tyrant. "I take it that fits the meaning of 'important'?" he added rhetorically.

With much hesitation, Gohan and Krillin left the Lookout to check on the others and bring them back. With the effects of Garlic Jr.'s Black Water Mist negated thanks to the Sacred Water, they didn't have to be worried about being attacked by their friends.

While this was happening, Kami and Mr. Popo worked together and imprisoned Garlic Jr. with the same method the elder Namekian has used to imprison the Makyan's father centuries ago. Now Father and son, their bodies and souls, were encased in black crystals and held deep within the temple. Never to see the light of day again.

As for Piccolo, after replacing his attire with his ki, he sat on a large piece of the Lookout that had been upturned from all the fighting and was watching their unexpected guest.

Cooler sat in the center of the Lookout courtyard, legs crossed in the lotus position with his tail curled around them, eyes closed and hands cupped in his lap with a marble-sized ball of ki hovering an inch above his upturned palms.

Even in his meditative state, he could feel Piccolo's sharp eyes boring holes through him. The reborn Frost Demon knew for a fact, given everything Frieza had done, trust would be in very short supply. It had been the same wherever he went where either his 'little brother' or 'father' had been.

When he considered his death, the last thing he expected along with just about everything else was being reborn as the older brother of Frieza and the eldest son of King Cold. With his advanced knowledge, he knew deep down how bad things were going to get, so for the many years he had been under his 'father's' watchful gaze he did his best to play the part of future heir to the malevolent galactic empire.

Many of those years he wished he could forget...the things he was forced to do for the sake of keeping himself not only alive, but for keeping what he knew a deeply guarded secret until the day he was strong enough to really start fighting back.

That was when things started to change.

Cooler's eyes snapped open when he felt a group of power levels approaching the Lookout. The energy floating above his hands faded away before he stood to his full height. "They will be here soon," he said, sending a look over at the Namekian. "If you have anything to say before they arrive, now would be the time."

Piccolo narrowed his eyes as he stood up as well. "You may have helped us deal with Garlic Jr., but don't be expecting a red carpet. Far as I'm concerned, you and Frieza are one and the same until proven otherwise."

"I can understand your reasoning." replied Cooler, "But consider this. If I was anything like my little brother, why would I give you all the chance to regroup, instead of killing you all off one by one?" his red eyes locked with the green fighter's black ones

"I don't expect you to trust me. All I ask is for you all to listen, what you do with what I say is up to you. Just know that I am not your enemy." continued the Frost Demon just before a Capsule Corp. ship appeared and landed on the edge of the Lookout. The engines powering down and the hatches opening allowing the passengers to step out and take in what had become of Kami's home.

"Jeez, you guys weren't kidding. Look at this place." said Yamcha as he looked at the damage that had been inflicted against the Makyans.

Gohan and Krillin got off the jet last, the demi-sayian being accompanied by his mother as they joined the others. It was then the group noticed the newcomer standing with Piccolo.

"So, that's Frieza's brother?" asked Bulma curiously, being the only one from their quest to Namek that hadn't seen the galactic overlord.

Krillin nodded, "Yeah, the resemblance is uncanny."

"Can we even trust him? I mean, with what King Kai showed us from the Otherworld..." Yamcha said, trailing off as he remembered everything the Kai had relayed to him, Tien and Chouzu when they were still dead.

"You know, it's rude to talk about someone when you think they aren't listening." the martial artist turned baseball player yelped, falling back on his ass when he turned and found Cooler right in his face.

Everyone else tensed, none of them had even felt him move!

The Frost Demon chuckled, "Sorry, couldn't resist." he held out his hand to the scarred man, who looked at it with more than a little hesitation before finally taking it and being helped to his feet.

"Everyone's here, so start explaining." said Piccolo sharply, leaving no room for argument.

Turning serious, Cooler addressed the whole group. "As your friends may or may not have mentioned, my name is Cooler, and yes I am Frieza's older brother. I came here to Earth to warn you all that my ego-maniacal little brother is still alive."

"W-WHAT?!" the group exclaimed in shock and terror.

"B-But how?! I mean, Goku killed him before Namek was destroyed!" Bulma shouted, not wanting to believe it.

"As a select few of you already know, my kind are amazingly resilient." said Cooler. "We can even survive the vacuum of space. Somehow Frieza survived your friend's final attack and the destruction of the planet they fought on."

"How do you know what happened? asked Gohan, Chi-Chi standing behind him with a worried expression and her hands on his shoulders.

The Frost Demon crossed his arms and looked up at the sky, "I was on the other side of the galaxy when I got word about what had happened on Namek. A few days after that, I heard that what was left of my brother had been picked up by one of his survey ships and was brought to a medical station where he got treatment and cybernetic implants for his missing limbs." he turned his attention back to the Earthlings, "It's only a matter of time before he's back to full strength...then he'll be out for revenge."

The air started to become more tense with every word Cooler had spoken. Each one of them thinking the worse case scenario from the idea of Frieza coming to Earth.

"Why are you telling us?" asked Master Roshi. "If he is your brother, why warn the people he would be coming after?"

Cooler sighed deeply, "Despite having the same blood, we are not family. Haven't been for a very long time now."

"Bad blood?" asked Bulma.

"He tried to kill me more than a dozen times. And he has had a serious grudge since I killed our father. 'Bad Blood' doesn't come close to covering it." the Frost Demon answered honestly, shocking everyone.

"You...killed your own father?" asked Chi-Chi, not liking the direction the conversation was going.

"Believe me, he was anything put a parent." Taking a few moments to collect his thoughts, Cooler decided to explain a little more. Even though he wouldn't reveal everything about himself, he would at least divulge enough to further gain the trust of Earth's defenders.

He had to if there was to be any hope of helping them in the future.

"Our father, King Cold, was a ruthless and merciless tyrant. He ruled the galactic empire with an iron fist, much like his father before him. Anything that stood in his path was either enslaved, or completely annihilated." he began to explain. "Friza and I were born of the royal bloodline of our species, one of us was to take the mantle when he stepped down from his throne. I was the first to be born, though it was done without a mother. I was created in a lab with the use of Cold's DNA and that of a powerful female of our kind. When I was 'born', as the first son, Cold did all in his power to groom me to be his heir. But it wasn't enough for him."

"Years later, Frieza was born much the same way I was. With two prospects working to take the throne, Cold would watch us and see who would be the best to take his place. Growing up was...brutal, for lack of a better word. Each and every hardship thrown our way was a test for weakness by our so called 'father'. And if we didn't exceed his expectations like he wanted...the punishments were severe."

In the way he said it, none of the Earthlings even wanted to fathom what he had meant. Krillin and Gohan cringed. Friza had been a horrifying and brutal creature, to know that his father was WORSE? It was hard to not pity anyone who crossed him.

"I did my best to protect Frieza from the worst of it when we were younger. He wasn't always the monster he became." Cooler smiled at the rare fond memories he had, "He used to follow me around a lot, try to be like me...he looked up to me." his smile bled away, "Then...Then he changed. He became a literal mini-version of our father. Killing in cold blood, destroying planets...he was no longer the little brother I once knew."

"How does all this fit into why your going against Frieza?" Piccolo asked pointedly.

Cooler shot him a look, "Because I never believed what he or Cold did was right." this revelation floored everyone. "From a young age, I believed that there were better ways to rule the empire than through fear and violence. I saw all forms of life precious in their own way. I had to watch as my 'father' mercilessly slaughtered innocent people simply to take their planet and resources, destroy entire worlds and species because they were deemed 'non-profitable' or 'useless'. I was forced to do horrible, unspeakable things to avoid being beaten to near death by the bastard that called himself a King..."

The Frost Demon trailed off, noticing that his hands had clenched and his power level was steadily rising higher and higher with his anger.

Taking a deep breath, he steadied himself and lowered his power back to a less threatening level. "Cold saw my compassion for life as weakness, and chose Frieza as his successor while casting me off our homeworld with the instructions to prove myself of the royal blood in my veins. To many, this exile would seem like punishment. But for me, it was freedom. Away from my father and brother, I started a long voyage to find myself. All the while training hard to get stronger."

He looked down at his hand and clenched it into a fist, "I was always stronger than Frieza. He resented me for it and always tried to beat me...but like our father he was arrogant with an ego bigger than a solar system. He never trained beyond what he deemed necessary. But me? I knew better. I knew that our kind could reach levels unimaginable if we pushed ourselves past our limits."

Cooler smiled to himself, "For years I traveled the universe. Learning many things and growing in power and mind. While at the same time using my strengths to help people who were in dire need. I had found a calling in protecting the innocent, and I was damn good at it. Which is what led me to what happened next."

Glancing at the group, the Frost Demon continued to smile. "With everything My father and brother was doing, I started helping those they enslaved. Retaking planets they had assumed control over, wiping out outposts that belonged to Frieza's army, whatever it took to throw a wrench in their operations. And the best part? They never knew it was me."

"Jeez, sounds like you took rebellion to a whole new level." Krillin commented, which got Cooler to chuckle.

"That's one way to put it." replied the Frost Demon, calming down and becoming serious again. "But, in the end. Not everything can go according to plan."

Memories came, ones that still haunted him. "I was eventually found out. And along with having me disowned with a massive bounty on my head, Cold sent me a message I wouldn't forget." his fists clenched again, but he kept a tight lid on keeping his energy in check. "That message...pushed me over the edge. I went back to our family's homeworld in a fit of rage. Anything that got in my way to stop me was obliterated with extreme prejudice until I was infront of my father."

"He didn't see me as a threat. I had done so well to keep my true power a secret and he had bought it so easily. That was his downfall. And in the end, it was his last mistake."

Cooler looked up at the sky, his gaze far away. "After that, I waged a one man war against everything my father and Frieza stood for. It wasn't revenge for what they had done, that wouldn't bring back what they had taken. But it was a form of justice that I was happy to get behind."

"In the end, I did end up becoming like Cold, only for a much better cause. Those who sided with Frieza saw me as a monster, a literal demon who wrought death and destruction. But for those I helped? Saved from my brother's tyranny? I was an archangel, sent to free them and give them hope."

The Frost Demon turned his attention back to the Earthlings, who remained in both shock and awe at his story. "And that is why I am here. I won't stand by and allow him to destroy this world like he has so many others." he smirked, "That, and I want to shake the hand of the one who kicked the shit out of him."

When he was finished, everyone was left with their thoughts. Many of them wanted to believe he could be trusted, but at the same time they didn't know if they could fully or not. While at the same time they were still enraptured by the tale he had given them.

Cooler stood and saw the many emotions that passed over the Z-Warriors. A lot of what he had said was truth, but at the same time he kept a great deal of detail to himself. As much as he wanted to tell them everything that he knew, he knew that he couldn't without seriously damaging the universe as a whole.

Everything was already thrown for a loop with him being part of this universe, it was surprising that many of the main events had continued unhindered in any way. But deep down he knew it was only a matter of time before something changed in a big way.

"Our guest speaks the truth." said Kami, surprising everyone as he approached with Mr. Popo dutifully at his side. "I sensed no deception in his tale. I believe that he can be trusted."

Cooler nodded to the elder Namekian, "I appreciate the vote of confidence."

"Do you know when Frieza will show up?" asked Yamcha.

"It's hard to say. It depends on his rate of recovery." replied the Frost Demon, "But knowing him as well as I do, and how humiliated he must feel after the beating he took from your friend, he'll come straight here the moment he can stand on his own again."

"Great, and with Goku still off in space somewhere, none of us stand a chance." said Krillin.

Bulma perked up, "Wait, does Frieza even know you're here?" she asked Cooler.

"No. And I'm keeping my power suppressed so that he won't be able to when he arrives. The moment he does, I'll deal with him."

"Piccolo raised an eye ridge. "And what exactly do you get out of all of this by taking him out?"

Cooler crossed his arms, "Aside from eliminating the biggest threat to the galaxy and ending our sibling rivalry indefinitely?" he paused and looked to the ground a moment, "...a home."

"Wait...what?" asked Yamcha, not sure he had heard right.

"I've never stayed in one place longer than I needed to. Living the life of a nomad for so long, I guess you could say I'm looking for a little stability." he approached the edge of the Lookout and looked down to the clouds below. "I've heard about Earth in passing. Compared to many worlds out there it has much to offer. And from what I have seen since arriving, I wouldn't mind setting roots down here."

Footsteps approached and stopped at his side, Cooler looked down and saw Gohan looking back up at him. "I don't think you're anything like your brother." said the half-saiyan. "And I know for a fact that dad would say the same and give you a chance."

"Gohan's right." added Bulma. "I mean, you could have wiped us all out when that mist was affecting us. Instead you helped put a stop to it."

"Not to mention warning us about Friza coming." Master Roshi threw in. "Can't say I'm completely sold, but you're off to a great start."

Yamcha nodded as did Krillin, both deciding to at least give him a chance before all eyes when to the Namekian among them.

Piccolo crossed his arms and turned his head, "Fine. But the first sign of trouble, the gloves are coming off. No matter how strong you are, I will do what it takes to stop you." he grunted out.

Cooler nodded, "Fair enough. I'll do what I can to show I'm a man of my word." It was a start, that much was more than he had expected. Hopefully they would all come to trust him completely, but there was plenty of time for that.

Red eyes going back to the sky above the Lookout, they narrowed sharply as he thought of Frieza and him imminent arrival to Earth.

"I'm right here, 'Little Brother'. Soon it'll be time to end our little feud, then you can rot in Hell with Cold for what you both have done. I'll avenge every life you have taken...including hers."
