Chapter Five!

Then There Were Ten - Part 4 (From Season 1 Episode 1)

31st of May 2001

Just before the killer flying saucer could attack, a spade appeared swinging in a snappy arc that caused it to bury deep within the saucer. "Back off sparky, no flying tree trimmer is going to hurt my cousin." Gwen growled as she hit it a few more times to make sure that it was down and out for good.

"Never thought I would say this, but I'm glad to see you." Harry chuckled as the flying saucer sparked lightly.

"We might not get along, but I don't want you dead." Gwen replied truthfully as the flying saucer began to catch fire. Seeing the signs, the two were genre savvy enough to realize what was going to happen, so they took off as fast as they could back towards the Rust Bucket, just barely outrunning the explosion.

o0OoO0o

When they got back to the Rust Bucket they found their Grandpa had returned. When they told him what happened he was understandably upset, "I was worried you would become overconfident with that thing on your wrist. That's why I told you not to play around it until we know what it is."

"I understand Grandpa, and I'm sorry," Harry apologized, "but at least I found out how it works." He went on to explain what he'd learned.

Once he was done Gwen joked, "How about finding a way to stay as a cool alien and not turning back as a geekazoid."

"I wish I knew how to, that'd be awesome!" Harry gushed, eyes sparkling, completely ignoring Gwen's tone. He sobered as another thought occurred, "At least we know one thing, Gwen was at least partly right when she guessed bad guys were going to come after this thing. We know that someone or something is after this watch."

Max was worried, he knew a few powerful criminal aliens who would want to get their hands/claws onto the Omnitrix. "If this is the case, we better help you learn to control and master that watch and fast. Who knows who might be looking for it?"

And like a jinx they heard an S.O.S massage over the RV radio. "Mayday, Mayday! Somebody help us! You might not believed this, but we're been attacked by some kind of huge robot!"

"It sounds like those things that attacked me earlier!" Harry said worriedly. He looked at his watch as he said, "He must be looking for this watch. Those people are in trouble because of me..."

"It isn't your fault." Gwen snapped him out of his funk, "You didn't know this was going to happen, so don't blame yourself for something you had no control over."

Harry smiled, a bit happier about it, "Thanks Gwen, and I think this is one of the cases where I can help them?"

"You? What are you going to about it Tennyson?" Gwen asked worriedly.

Harry smiled as he looked his watch. He looked back up and smirked, "That robot seems to be looking for this watch, well I think we should give him what he's looking for..."

Both Gwen and Max smiled at this idea too, if Harry was able to transform into powerful aliens, one of them must be able to help with the robot. So the three Tennyson ran out of the Rust Bucket and headed toward the other Camp Site.

o0OoO0o

As they got to the edge of the Camp Site Harry pushed the button on the watch and turned the dial counter. He knew he couldn't use the fire guy, not with so many cars and camper vans about, it would make things worse than better. So he looked though it and saw one that might help, a diamond looking alien. Picking that one, he pushed the dial counter down carefully and transformed.

A flash of light later and he stood at an even seven feet tall, his body covered, or maybe outright made of, green crystal. On his back, Gwen and Max saw two large spikes, jutting from his shoulder blades, and when Harry turned around, two smaller one lower down his back.

"So, what do you think this guy can do?" Gwen asked as she Harry's new form.

"I don't know, but I bet it is going to be something cool!" Harry exclaimed with a wide smile as he flexed his hands, examining them and the tinkling glass sound he seemed to make with every movement.

They all rushed into the camp ground to see a huge robot stomping about. It had similarities to the saucers from before, but not very many. It stood as tall as a two story building on three sturdy looking legs. Its chest, neck, and lower body were all a single piece, shaped like a sharp point at the bottom and thickening towards the head, which sported a single visor with a red light that scanned back and forth. Its arms were proportioned to the rest of it, band had four claws on each hand, with a red cannon in its palms that fired blast after blast into the RVs and cars, "Looks like the papa bot this time." Harry said dryly, "Grandpa, you and Gwen help the campers and get them to safety, I'll get gear head's attention."

Sprinting forward Harry reached the tripod just as it picked up the Park Ranger. "If you want to pick on someone try me metal head!" Harry yelled to get its attention.

The robot turned to the new potential threat, only for its scanners to detect its goal on the new arrival's chest. The Park Ranger screamed briefly as he was dropped suddenly, but it didn't last long as he landed on a car after only dropping a few feet. With its attention now on Harry, it fired a laser blast straight at his chest, throwing him back into one of the RVs.

Harry groaned, but found that he was completely uninjured by the blast. Unfortunately, he was currently stuck inside a cage of twisted metal. 'I wish I had something to cut myself free with.' He mused, only to stare in surprise as his arms sharpened into blades.

With a boyish laugh of delight he effortlessly slashed his way free, the metal giving barely any resistance at all under his crystal arm blades.

He had to get serious again though as he saw the robot stomping his way. With a war cry he charged forward, one blade at the ready to slash while the other was kept in front of his for defence. It was useless though, because when he made to dive at it the robot jumped straight up in the way.

Harry looked up just in time to watch as the three legs began spinning like some kind of massive upside down helicopter.

"Ooh, that doesn't look good..." He muttered, just before the robot dropped like a rock towards him.

Meanwhile, as Harry was being smashed by the giant robot Max and Gwen were helping the people to get away from the fight between two titans. As they helped the campers they saw the Park Ranger drop from the car he'd landed on and ran over to help. "What the hell is going on here?" The terrified man cried.

"You wouldn't believe me if I even told you, now come on!" Gwen urged before she and her Grandpa ran off to help the other campers again.

As they left the Park Ranger looked over his shoulder, bewilderment clear on his face as he saw the crystal monster being thrown by the giant robot towards him. It was by luck that he moved out of the way as the crystal monster landed on his car, destroying it even further. The Park Ranger, now convinced he was way out of his league and over his shock enough to actually register this fact, took off running as fast as he could.

Not having any idea as to what other abilities his current form possessed Harry had keep on running, trying not to get hit by the laser beams from the robot. However, as he ducked the next laser attack the beam of energy hit the tree that Harry saw was about to run past.

A scream alerted him to the presence of Gwen underneath the falling tree and, without thinking, he threw himself over her. He just hope the spikes on his back didn't get stuck, and that his new form was strong enough to resist the weight. Once more his thoughts seemed to activate a change in him, and a massive wedge shaped crystal grew on his back. The weight of the falling tree and the sharpness of the blades made short work of the tree, splitting it straight down the middle, each half laying on either side of Gwen and Harry.

"We even?" Harry asked as he took a step back.

"Even." Gwen breathed, staring at the tree halves with wide eyes.

Before either of them could say another word Harry was grabbed by the robot by the arm, which it proceeded to try and pull off.

Harry grimaced as he felt the hairline fractures form on his shoulder, only to instantly seal up. He wished he could do something about it, but he was being held in a firm grip and couldn't move. Just like before, his body seemed to morph according to his thought and, after a short grinding of crystal on steel, the robot's hand exploded, revealing Harry's entire arm has transformed into a mass of spikes. It finally sunk in how he was able to shift his new body, and his brain immediately tried to think up ways to use this new information as he landed hard on the ground as the robot stumbled backwards.

It wasn't as distracted by its lost arms as he thought though, because with a flash of light, heat and sound he was thrown back into a nearby cabin with another laser blast.

"Harry!?" Max cried, having just seen the hit as he helped Gwen find an appropriate hiding spot.

He didn't have to worry though as Harry was able to get out of the burning building just fine, the fire not able to find purchase on his sleek crystalline form.

With a snap of his arms he willed his arms to become blades again, prepared to cut the robot apart. Before he could even get close though the robot raised its hand and fired another blast his way.

Reacting quickly and instinctively, Harry raised his arms defensively. His eyes widened as the beam split into two boozed smaller beams, flying in every direction as it hit his arms. He winced as one of the ricocheted lasers whizzed past his Grandpa and cousin.

Getting an idea from all this, Harry raised his voice, "That all you got, ya tin can?! Gonna have to do better than that to beat me!"

Whether the taunting worked or the robot simply computed that more power was needed wasn't certain, but with a loud sizzling sound and a few seconds of charging, a beam of orange energy poured from the tripod's palm. Unlike the previous shots, this was a continuous beam whose goal was to wear Harry's crystal body down until there was nothing but the Omnitrix left.

Harry smirked as his plan worked either way, and brought his hands together, forming a sort of dish shape with them. "What comes around, goes around!" Harry called. It was just large enough to stop the last, and the energy reflected off his hands, condensing into a pencil thin beam of blinding white energy that was sent back in the tripods direction.

Seeing as the speed of light was what it was, the tripod didn't manage record the actual blast that killed it for even a full second before it exploded, a red line of molten metal splitting it in a jagged vertical line from head to pointy bottom.

Seeing the defeat of the robot both Gwen and Max jump up and down in joy. "Way to go Ha-Diamond... headed... guy?!" Max trailed off lamely, realizing that people were looking at him and Gwen. He didn't want to reveal his grandson's identity, though it was a foregone conclusion if things like this kept up.

Harry felt like joining them, but since he was currently a thousand pound crystal creature he decided against looking like an idiot. Instead he decided to beat a hasty escape. Stealing a move from a comic book superhero character Iceman, he held a hand out in front of him and slid on the sheet of crystals he shot out of them. Before the Campers knew what was going on Harry was off, the trail behind him rapidly breaking down into dust that blew away in the wind.

As the campers were wondering amongst themselves over who had saved the Gwen and Max slipped out unnoticed.

o0OoO0o

It was early the next morning and Max and Gwen were up and picking up their Camp Site to leave for their next stop of trip: Washington. The night before the three of them talked about the day and the three aliens Harry could transform into before heading off to bed. Now it was morning and Max couldn't find Harry, "Gwen do you know where Harry is?" He asked.

"I don't know, haven't seen him since breakfast." She answered.

That was when they heard something like a racing car approaching rapidly. Before they could even turned their head something appeared, followed by a trail of just that caught up several seconds later. When the dust cloud cleared and they could see it again they saw something, clearly another alien, judging by the symbol on its chest, that looked like a semi-armoured Velociraptor with a helmet and a visor. It's tail had five blue stripes down it while the rest of his was either white or black.

"Harry?" Max asked just to be sure.

"Yep!" Harry returned as the visor slid up to reveal the aliens face, which turned out to be blue with green eyes and thin black lips, "Watch this Grandpa." The visor dropped and in another burst of speed unlike anything they'd seen before their Camp Site was cleaned and packed up within seconds.

"Pretty fast, huh?" Harry asked as he timed out and transformed into his human self, and said, "I think this is going to be the best summer ever.

"Absolutely Harry, just try not to break the sound barrier near the Rust Bucket, or us." Max said with a smile.

"Definitely going to be interesting if nothing else," Gwen shrugged, "So where have you been anyway?"

"Oh I had to sort out a few things before our holiday could start rolling." Harry said with a malicious grin on his reptilian face, climbing into the Rust Bucket, leaving the other two to wonder what he had done. Knowing that they weren't going to get any answers from Harry, they too got onto Rust Bucket and left for Washington.

Elsewhere:

What Grandpa Max and Gwen didn't know was that Harry went back to Bellwood to find J.T, Cash and Justin where he found them outside of Mr. Smoothy. Using the speed of his new alien form Harry hung the three from a branch by their underwear.

With a growl and a useless flail, Justin exclaimed, "Guys, what the hell happened?"

"I don't know, it all happened so fast!" J.T. whined.

"Can you guys get down either? It's starting to hurt up here." Justin asked.

More useless flailing followed his question. The three boys eventually had to resort to pathetically calling for help from the nearby kids, who began laughing at them.
