Gumball woke up from his bed aching. Despite all the rest he got when he ran back home after leaving the Fitzgerald household, he felt tired and sore. He stretched and walked downstairs and into the kitchen for a bite to eat.

"Morning Mom..."

"Good morning honey, how are you feel-" She turned to Gumball and stared.

"What?"

"I never thought the injuries would go that fast..."

"My injuries are gone?"

"Faster than I would've ever imagined, it's like the cuts were never even there."

Gumball looked at his paws and forearms, looking at the scrapeless limbs with no signs of scars. "Wow! This is sweet! Now I can go outside without having a problem. I'll get ready for school!"

Gumball rushed upstairs like a blur to get clothed and to shower. "Never seen him so motivated for school, must be pumped for something." Nicole said, preparing to make breakfast.

"Sonic, I think I have a game plan for the fight against the robot from yesterday. We use the red wisp to use it's power to assist us."

"I was thinking the same thing, but where is the little guy?" Sonic asked. Gumball walked into his room to see the red wisp glued to a now active computer screen, it's tentacles on the mouse as it scrolled through website after website, and scrolling into his social media.

"Hey hey hey, can you please not go onto the computer like that?" Gumball said, "I don't want anyone invading my privacy." The red wisp came into concentration and nodded, floating away and about in the room.

"Are red wisps usually like this?" Gumball asked Sonic mentally.

"They tend to be scatterbrained like this, but they show to have a lively, fiery nature to themselves."

"Alright, let's brief the wisp and Darwin, and get to school!"

At school, Gumball, Darwin, and the red wisp were at the track field at lunch. Darwin was eating his lunch and wearing a whistle, blowing every once in a while after swallowing a bit of his food. Gumball would move halfway along the track every time Darwin blew the whistle and do all sorts of exercises, with the wisp moving along with Gumball and attempting to do the exercises as well.

"Hey Darwin." A female voice said, Darwin recognized it.

"Oh, hey Penny. What brings you here?" Darwin asked.

"I heard from Alan that Gumball was going to be out here for lunch."

"Yeah, he decided he wanted to take a ton of his free time here at school in order to get some heavy training done." Darwin blew the whistle, the cat rushing around the track halfway once more and performing different exercises.

"Even with all that pain from yesterday he's just going at it like usual, such determination."

"Gumball briefed me a plan for tonight so we can take out the robot at a quicker rate."

Darwin blew the whistle again, this time Gumball now running a lap along the track and heading to the bleachers where the two were.

"Hey Darwin, I'm going out for a lap around Elmore to get part 1 of the plan accomplished. Oh, hey Penny, never thought you'd be here to watch me train."

"I wanted to check up on you to see if you weren't hurting too bad from yesterday." Penny said.

"I'm fine, not hurting that bad, got a back ache here and there." Gumball stretched his legs. "Alright, I'm off, and don't forget to practice Darwin, it may be the only time you can!" the cat said as he sped of into Elmore.

"Gumball was speaking of a plan?"

"Yeah, it's why I'm going to be practicing." Darwin went out to the field in the middle of the track, the red wisp following. "Hey Penny!" Darwin yelled out.

"Yeah!?"

"Even from this distance, it's best for you to stand back! Gumball said these guys are extra explosive!"

After school, Gumball, and Darwin were walking down the street with the red wisp floating with the two.

"Want me to rebrief the plan Darwin?"

"Sure."

"Alright, during my run at lunch time I placed the Blue Chaos Emerald in the destination we're going to be, and the robot is going to take it as bait and you're going to use the alien's ability, Red Burst, to distract and smush his defenses with your ability to jump an infinite amount of times and explosive capabilities, while I go in for the finishing blow."

"Well, where did you take the Emerald, and how do you know that the robot didn't swipe the Emerald while we're in school?"

"I placed the Emerald not too far out in the desert, it'll be a little while for Eggman's machines to sense it and the robot will be here when we'll be there, now let's hurry! I can't wait to smash that metal coat into a ball of aluminum foil!"

Roughly 30 minutes later, Gumball and Darwin were in the desert, each hiding behind large rocks. Between the two rocks laid several meters of desert, with the Emerald laying on the sand in the middle of the vast bed of sand.

The sound similar to a jet is heard from afar as the familiar craft of metal Gumball face descended near the Emerald.

"Just as planned..." Gumball moved and raced forward, catching the robot off guard and launching it back with a powerful and swift kick to the head.

The prototype got up from the impact and drew it's energy blade, going in for it's first strike, rushing forward to slice at it's fast opponent. Gumball made a swift dodge and moved in on the offense, only to be blasted back by a wave of energy from it's arm cannon.

Gumball spinned about from the blast, hitting the desert floor several times over several meters before getting to his feet and skidding to a halt. He launched forward and at the prototype, making a powerful strike which was countered by the arm cannon, making an impact hard enough to create what seemed to be a mini-sonicboom.

A large cracking sound and a shockwave was generated from the two as they starting going at each other, creating these sonicbooms on every impact made.

Darwin hid behind the rock, terrified. He peeked at the two as they brawled, clashing over and over, sand flying with each impact.

"Alright, we just attack when Gumball gives the cue, we go in...S-Shouldn't be that bad, right?" Darwin said to the red wisp.

The wisp nodded, and peered above the rock to see Gumball get his chance to strike, slide kicking the prototype and kicking it behind his position.

"Darwin, now!"

Darwin rushed out. "Here goes nothing!" Darwin felt a quick surge of power as he transformed into a bright inferno, rushing into the prototype.

"Nice! Now let's bring him down!" Gumball said as he rushed forward and boosted, knocking the prototype into the air.

"Darwin, jump into him!"

"Got it!" Darwin started to jump up, creating small explosions as he continued, slamming into the prototype and charging up for an explosion.

Darwin erupted, going into a blinding light as he exploded, the now charred prototype getting slammed into the ground, able to be targeted by Gumball, who quickly boosted into the prototype.

"Heads up!" Gumball said as the prototype flew into Darwin, which in reflex blasted the prototype back at Gumball. The cat made a swift kick, slamming the prototype in the ground.

The prototype quickly levitated back up and began a quick, powerful assault on to Gumball, sand and energy blasts ablaze across the sandy floor.

"Darwin! Explode now!"

Darwin started to charge up for a final blast, charging for what seemed to be hours as he watched his brother fight against the metal adversary, the two clashing back and forth, causing mini-shockwaves and sonic booms similar to what happened mere moments earlier.

Gumball collided with the prototype, clashing once more, using his paws and what strength he had to hold the robot's deadly weapons away from contacting his body. He looked up at his flaming brother above the arid battlefield.

"Now!" Gumball cried out as he moved, spiinning the prototype with all of his might and launching it torwards Darwin, propelling it with a strong kick into the back.

Gumball flipped back and started running backwards as he watched Darwin explode in a bright blazing inferno, causing the ground to shake and tremble as the bright flames were soon clouded by soot and dust.

Gumball rushed in to see the bright cyan color of the prototype energized saber. It was alive, but it had to be severely weakened. If he wanted a chance, he had to do it now. He rushed in, breaking the sound barrier and boosting into the prototype, preforming powerful hit afeter powerful hit until he hit the machine with a strong, forceful homing attack to the neck, which forcefully ripped the prototype's head clean off. They had won.

Gumball's onslaught cleared up a majority of the dust in the vicinity, but due to Darwin's eruption a large but shallow crater remained where once tons of sand was.

"Gumball! W-We've won!" Darwin said as he ran to Gumball, the wisp following behind.

"Yep, we did it!" Gumball said as he gave a thumbs up to the two.

Metal parts in the prototype started to loosen as out of the prototype's neck crawled out a bright cyan wisp, somewhat similar to the prototype's design. It's head had a small pointing structure from it's head, and it had two narrowed eyes with orange pupils with auburn irises. The wisp had 3 tentacles, one shaped like a lightning bolt, with the other two looking similar to arrowheads.

The wisp quickly floated up and observed it's surroundings, it's attention quickly being interrupted by the sound of static.

"Oh ho ho ho!"

"Eggman!?" Gumball said as he looked around, only to find that it was coming from the head of the prototype. It was an audio message.

"So you ended up defeating my 3rd prototype eh? No matter! I have big plans, and a whole new Egg Fleet already in the skies here to rule the world! Oh, and to also salten you up, I even captured your little friend!"

"Sonic!" a fairly young voice said.

"Tails!" Sonic said. "That's Tails' voice!"

"I hope you'll be here soon, because he's soon going to be my robotic servent to fight against you! Oh ho ho ho!"

"You won't get away with this Eggman! Sonic will be here to stop you!"

"Quiet you! Well then Sonic, are you brave enough to take me on, or are you a scaredy cat!? Tah tah!"

"Eggman..." Gumball said, clenching his fist. "It's one thing to capture my friends and turn them into robots, but when you do that to Sonic's best friend Tails..."

"Gumball, what's going on!? What's going to happen?" Darwin asked.

"Darwin, go home and say I'll be late tonight..." Gumball said as he brushed some dust off his sweater. "I'm saving Tails."
