The Toxic Mutants made their way through this land, leaving their home for the first time to find that much of what Vac had said was true. This place was no longer a place of beauty, was no longer a home to their former find. Now, it was corrupted, warped...violated by their enemies.

Where there were once streams and clearings, now their stood pavements and buildings where people went about their lives with ignorance to their destruction of what came before. Where once creatures flocked, now metal steeds that spewed out fumes that rose into the skies filled the pathways that their ancestors once walked to watering holes and mating grounds.

"Then what this Vac says is true." The leader stated. "They are the ones destroying what is ours by right!"

"It sickens me to see." The pink, blobby one answered. "And yet, now we are no longer of that world. Now, even I am strengthened in this place."

The others looked at him, but their vastly-expanding minds had come to the same conclusion. There was a time that the toxins that created them had made them sick and weak, but now in their new existence, it nourished them. The air, which no longer smelled like the clean, uncorrupted air they had known in their early days now seemed to give them a sense of comfort and ease. The fluids that had seeped into the earth, and by extension into their food supply now gave them vigour and strength.

"What do we do Bluefur?" The remaining mutant asked in a low hiss. Bluefur just looked to him, hearing this name. "The one named Vac said we needed names."

"I like it." Bluefur answered. "From now on, you shall carry the name Hisser."

"Bigs." The pink, blobby one offered, before looking to the city. "So, what now?"

"Now, we show our enemies the error of their ways." Hisser answered, seeing a man walking down the street, eating a burger. He threw the carton aside with absolutely no care where it landed, despite the fact there were numerous trash cans around. Hisser leapt from his perch, and landed in front of the man.

"That...that is not the way to treat your world." Hisser said menacingly as he approached the terrified man. He turned, finding Bluefur and Bigs behind him.

"Please, don't hurt me!" He begged them. Hisser just laughed.

"And how many pleas from how many creatures have been ignored by your kind?" He asked. "What right do you have to ask for mercy now?"

"Please, I'm...I'm important...I have money!" He rushed out, trying to think of ways to talk his way out of this nightmare. "What do you want? I'll get it for you, I promise?"

"How about our world back to the way it should be?" Bluefur asked him. "No? Well...how about us back to the way we should be? No? Ah, well...then perhaps there is something we can offer you."

Bigs picked up the polystyrene container for the man's burger, and threw it to Hisser, who caught it. He scrunched it up in his hand, and approached the man, seizing him by the neck. The terrified man called out in pain.

"We can give you a lesson in putting your waste, where it belongs!" Hisser answered, shoving the carton into his throat and holding it there as the man choked, fighting desperately to get him to release him. "Let's see you choke on your own filth!"

The Rangers got to the gas station, and looked around. Tensou had warned them that the new threat was heading this way. They were all morphed, all armed, and all ready for battle. The fact that the gas station was here created a new threat. Not only was the station here, there was a tanker, filling the station with a week's worth of gas. So much combustible material made the whole place a potential bomb, one that easily had the power to take out most of the block. They didn't have the luxury of concentrating on their opponents. They needed to also isolate the threat.

"Emma, Noah, try and talk to the guy in the tanker, see if you can convince him to come back another time." Tory instructed them. "Jake, Gia...get ready nearby. We might need to set up barriers if it looks like this place is a threat."

Just as they were about to move, a powerful blast sent all of them to the ground. Hisser, Bigs and Bluefur all walked into view.

"So, from what we understand, you are the Rangers." Bluefur greeted them. "So, you are the ones that stand as champions for this...slight on the face of our world!"

"Um...what?" Noah asked, completely confused. "Your world? You're Aliens! You came here!"

"We were always here! It is your kind that poisoned our homeland!" Bigs called back. "However, instead of wiping us out, all it did was make us stronger, strong enough to show you the error of your ways!"

"What are you talking about?" Emma asked him. Bluefur just pointed to the gas station.

"This...this stands as an idol to your violation of the very world that you inhabit!" He told her. "You use the corpses of what came before you to poison everything all to make your fleeting existence a little easier!"

"Pollution?" Emma asked him. "You're saying you...you're angry about pollution?"

"We simply seek to cure the world of a virus." Hisser said angrily. "A virus we have come to know as humans!"

"I guess it's too much to hope we can talk about this?" Jake offered. The three Toxic Mutants rushed forward, preparing to attack.

"Does that answer your question?" Noah sarcastically replied as he brought his Bowgun to bear.

Back at the hospital, Mr Burley made his way into a side room. He had been bombarded from all sides since the disastrous field trip. His phone had blown up so much, that once he had finished calling the last of the kids' emergency contacts to inform them everyone was at the hospital, he had no choice but to turn it off. A couple of people had already arrived, and wasted no time in questioning his sanity, his logic, and his abilities as a teacher in taking his class out to a toxic waste site mere months after regular attacks by monsters had begun.

He hated to admit it, but he was questioning all of those things, and more himself. He had always sought to make his classes engaging, and get the kids thinking about what they were doing, and what science meant to the world throughout his career. In his first week as a fully tenured teacher, far more years ago than he would dare to admit, he had almost ended up with a pink slip straight off the bat, because as a practical demonstration of why safety rules existed in a lab, he had mixed a couple of chemicals on his desk, and ignited them with the friction from a centre punch hammered into the desk, causing a small explosion. He felt it would be a far more effective demonstration of how dangerous things could be in a lab than any hours-long lecture.

He had measured out the chemicals exactly, and knew for a fact the explosion he caused would be no more dangerous than a cap pistol, but that didn't matter at the time. Several people complained, and it was only the fact that not only was no one hurt, but his qualifications and numerous testimonies from his university professors that he had more than enough knowledge to know that it wasn't dangerous that stopped him ending up on the unemployment line. He had toned down his little demonstrations since then, but he still always wanted to give the kids a real-world feel for what science was and encourage the same passion for it he had.

He had to admit that on paper, things didn't sound good. The town was in a state of...well...he wasn't sure war was the right word, but they were certainly under attack. The monsters had been coming to the city for a couple of months. The scientist, and conspiracy theorist in him was intrigued, and wanted to know more, but the danger was always present. It had been hard enough to convince the education department to sign off on a field trip anyway, but now he had returned with half his class needing hospital treatment, he was certain that the PTA and the education board would be looking for someone to blame, and he was the obvious choice.

A nurse came in, seeing him on the couch, and quietly went about her business. She could see he was upset, and looked to him.

"Everything's being done and..." She paused as she saw him. "Mr Burley?"

"Um...yes?" He asked. She just smiled and gestured to her name badge.

"It's me, Linda!" She told him. "Linda Kyle? I was in your class!"

"You...you were?" He asked her. "Well, I guess you got out in one piece."

"That school trip, that was your class?" She asked. He just nodded sadly.

"They're all here because of me." He grumbled. "I should never have taken them on that trip. The PTA's going to be looking for my head on a pike."

"I...don't think they do that anymore." Linda offered weakly. Mr Burley didn't seem to be in a mood to take the joke though.

"I was responsible for their safety, and what do I do?" He asked her. "I take her to the most polluted place in the city you don't need a Has Mat certificate to get access to! It's a miracle no one's died!"

"Mr Burley, you can't blame yourself. No one could have predicted what was going to happen." Linda continued. "From what I understand, you were attacked. That's not something you could help."

"Well, if I'd kept them in a class with textbooks..."

"Mr Burley, what happened isn't your fault." Linda assured him. "If they have any sense, they'll see that."

"I just...I've had parents screaming at me most of the day, the education department's called...I can't help feeling..."

"It's a witch hunt; you can't take this to heart." Linda told him, sitting with him. "You're an amazing teacher."

"Maybe...maybe it is time I retired." He suggested. "Maybe it is best I'm not responsible..."

"Mr Burley, that would be a horrible thing to happen." Linda put down flatly. "It's because of you I'm here."

He just looked at her as Linda smiled.

"I was wasting my time at school, but you pushed me. You challenged me and made me think about stuff, stuff I just took for granted." She told him. "By the time I left school, I went into nursing. It's been the best thing that ever happened to me."

"Well...that might be one success story." He said dejectedly. "But half the kids..."

"I'll tell you what, I'll see if I can't get you an update on most of them." She suggested. "Strictly speaking I shouldn't, but I'm sure I can tell you they'll be alright."

Before he could answer, she got up and left. He lay back on the couch, exhausted from the strain the day had put on him. He couldn't help feeling guilty about what had happened, and knew that in time he would have to answer a lot of difficult questions. All he could hope was that nothing terrible happened to the kids. He would take the fall with good grace if it was his fall to take. The one thing he cared about was that the kids wouldn't suffer as a result of his actions.

Back at the site of the battle, he arrived, seeing the battle already underway. He still had no idea what was driving him, or why he had come. All he could see was three monsters fighting the Rangers. The Red Ranger was fighting a large, blue-furred creature, while Pink and Blue were facing one that looked somewhat like a snake. Yellow and Black were being pounded into the pavement by the last, a pink blob of a creature.

He took in a deep breath, and the stench of pollution assaulted his nostrils. He could smell from here the filth that had created these creatures, and it stirred something inside him. He watched as the Red Ranger landed in a heap. The Pink and Blue Rangers were already down, not far from him, while Black and Yellow were a little way off.

"What the hell are these things?" Noah screamed. "They're killing us!"

"What are we meant to do against these things?" Jake protested. "Our attacks keep going through this guy; it's like trying to staple a Jello to the ceiling!"

"These guys are tough!" Emma agreed, firing her Phoenix shot again, only for Hisser to avoid it in lightning-quick motions. "What can we do?"

In his place of cover, he felt something stir inside him, and the flesh on the back of his neck felt like something was pressing through. Without a word, something inside erupted. The last thing he saw before the last of his consciousness faded was seeing metal armour form around his hands.

Emma continued to fire shots at Hisser, but he weaved around them with ease, before reaching her, grabbing her tightly. He wrapped his tail around her neck as he tossed her weapon aside.

"You...you protect the ones that did this to the world." He commented.

"We...We protect the whole world." She gulped, struggling for breath.

"Your kind created us, and now you stand in their defence." He stated. "That makes you the enemy."

"Created?" She asked him. "What...?"

"You protect everything?" He taunted her. "Do I look like I need protecting?"

The others watched helplessly as Emma was slammed into the concrete, shattering it beneath her. They were quickly by her side, but that turned out to be a mistake. Hisser whipped his head backwards, before spewing forth a torrent of toxic filth that engulfed them. All off the Rangers instantly fell to the ground, struggling to move.

"It...It's burning!" Gia grunted.

"I feel so weak!" Noah added. "What is this stuff?"

"It is a small taste of your own medicine." Hisser replied. "It is a taste of the poison you've inflicted on us for years!"

"The question is, do we let you suffer as we have?" Bigs asked. "Or do we just finish you now?"

"I say, we make an example of them." Bluefur stated, gripping his mace tightly as they advanced. Just after that, all three of them were sent flying by blasts. The Rangers all looked for the source of the assistance, seeing someone in the shadows cast by the petrol station and the gas tanker. He was too far away, and still shielded by shadows.

"Who the hell is that?" Jake asked as he started to advance. Troy saw the three Toxic Mutants powering up a blast.

"Guys!" He called out. They were already weakened, but saw the threat. Gia and Jake slammed cards into their morphers, raising barriers around the gas station as the blasts fired out, to funnel the destruction away from nearby buildings. Noah used the Defenstream to keep the worst of the fireball under control. They all collapsed, barely conscious from the effort, but the gas station and a large portion of the street were already aflame.

"So much for that." Bluefur snorted. "Now, what to do about..."

He stopped as he heard steel grating against concrete. The three turned to see pieces of wreckage moving. From the inferno, they could barely see a figure striding towards them.

He strode out, the flames not affecting his advance. His focus had mechanical precision, and was as implacable as steel. He came into view, flames flickering around him, reflecting off his armour. Emma looked up, not believing what she was seeing.

"That...that symbol." Troy stammered, seeing the glyph of Gosei, the same one that was on their helmets on his forehead. "I've...I've seen him before, in my dreams."

"I am a Guardian of the Earth! I am Robot Knight!" The stranger announced as he stepped onto the street and into view, letting the Rangers all see him in full. He stood before the Toxic Mutants, who considered him for a moment, before attacking. The Robot Knight just drew a weapon from a sheath in his waist, forming it into a sword and ran into battle.

A/N: Yes...that's right...I'm taking the origin and story of the Robo Knight...screwing it into a ball...and tossing it straight in the recycling bin! No disrespect to the writers of the show, but I personally find Robot characters pretty bland and uninteresting (with no emotions, where is there to go?) So, I've got my own version. Hope you like it.
