There was no doubt in Mako's mind what had to be done. Raising himself up back to his full height, smirking as he felt multiple sonic booms burst out from his leviathan form, he raised his foot over a random section of Tokyo. For seven long seconds, he let it linger over several hundred stores and residential areas, giving everyone the chance to fall into the lowest pit of despair as they realized that their fate had been abruptly sealed. Then, using the increased pull of gravity on his grossly magnified body to his advantage, he let himself fall through the heavy girth of the atmosphere and stomped down with all his might.
There was no resistance; thousands of towering spires of steel and glass were instantly annihilated, as everything, cars, people, streetlights, roads, parks, and all, was compressed into one indistinguishable mesh of twisted viscera. Their demise was punctuated all the more by the titanic explosion of dirt that followed, a tidal wave of compressed air and kinetic force rocketing outward like a bullet train as everything within a 30-mile radius was reduced to smears. From the most formidable stone pillars to the meekest flowers, all were equal in their pulverization. When the towering pillar of smoke and debris had cleared a little bit, all that could be seen was an indistinguishable pile of nauseous greys and browns, the Earth now forever scarred.
As he lifted up his foot, Mako could feel bits of debris and trickle down from his soles, which felt sticky from the tangled mess of oil and blood that was now fused into his skin. Without delay, Mako immediately took another step, and a few more square miles of city disappeared beneath his soles, as thousands of more people were reduced to a fine red mist. A casual wiggle of his toes was enough to finish off any stragglers that happened to be left behind and bring down the remaining buildings that were somehow left standing between his toes. By now, the capital was awash with a tsunami of pure terror, as countless people for miles around fled from their homes. Military forces from all over the world had already been called in to dispatch the miles-tall kid that had appeared seeming from the ether. They knew deep in their hearts, however, that they would do nothing against the monster that now had free reign their city, who looked prime to rampage around the country to his heart's content until there was nothing left.
He continued on like this for a while, bringing hell down on every bit of the sprawling metropolis that he could, as though he were a child gleefully stomping down on an anthill. And in a very literal sense, he was. But for some reason, Mako suddenly realized that a part of him... didn't feel entirely into this.
That couldn't be right, though. He should be having the time of his life right now, as he brought down his feet on yet about district, sending hundreds of once-towering skyscrapers down to the Earth they once sprouted from.
Instead, however, he felt... nothing. He didn't want to admit this, but... he was starting to get bored. Not just bored as in "I'm kind of exhausted from doing so much of this all at once", but bored as in "God, none of this is actually fun!"
Something definitely seemed off about all this compared to the kaiju monsters he was familiar with. In all the movies he watched, the whole city was sprawled out in front of those tyrannical beasts like a vast urban playground. They were tearing through entire concrete buildings like nothing with everything that they had, using the claws to pry open dams, or their tails to topple down hospitals. There was no end to the amount of things that they could do to bring down their wrath upon an entire metropolis.
Meanwhile here he was, still stomping down on the same indistinguishable little boxes as always, still feeling nothing as they came down so easily like they weren't even there, still standing around looking like an idiot stomping down on these pathetic dust mites!
With a frustrated shriek, he kicked away at the ground in one long, wide arc, sending the entire district of Shinjuku flying across the stratosphere before raining down miles away on the outskirts, glaring down at the ground as though it were somehow Tokyo's fault that he was enjoying annihilating it from existence. He didn't get it! He thought that this would the chance to finally get to experience what being a kaiju was like, and this was what he got!? Was it supposed to be this boring!? Why wasn't he having fun!?!
Then it abruptly hit him. He couldn't believe that he would ever feel this way, but in hindsight, there was the only thing that made sense:
He was way too big!
In every single kaiju movie he'd seen, most every single monster was at most tall enough to have their heads peeking out over the tallest skyscrapers. Whether it was Biollante and her wicked rose vines, or Dogora and its terrifying cellular tendrils, there was one thing that they all shared in common, and that was their intimacy. Every tower that they toppled, every missile that they tanked, that required their full might to achieve. Everything that they did was a demonstration of pure, raw power, a tour de force of the true beauty and terror of both Earth and the cosmos itself!
But Mako? He was way bigger than any of them! There was absolutely nothing for him to show his full might towards, that required him to showcase even a little bit of his destructive potential. Everything that could have possibly been a threat, that could've showed the full extent of his might, was so laughably insignificant compared to him, so pitifully puny, that he was causing ten times the destruction that those monsters ever did put together just by standing here! How could possibly be intimate with the city he when all there was for him to be "intimate" with was what were effectively grains of sand!?
In a way, Mako guessed he should have felt proud of this. A lot of those kaiju, for all that they were living hurricanes, forces of nature that couldn't be stopped or reasoned, still occasionally faced significant opposition from the puny human armies, still occasionally were humbled by the man-made towers that served as symbols of man's triumph over nature. Meanwhile for him, those same towers couldn't even reach past his toes! If he wanted, he could completely destroy all of Tokyo in the time it took him to make a sandwich. It wouldn't even be in the ballpark of hard; it'd just be him walking around for a bit!
But the thing was, that wasn’t fun at all!
...he supposed it was probably too late at this point to back down from his little rampage and make peace with humanity. He'd already annihilated most of downtown Tokyo without any regret. Millions of people were probably dead because of him, which was... it somehow didn't feel real, but he knew that it had to be true.
That...also probably included his parents too. And all of his friends. But at the same time, they were probably already pulverized by the instant growth he experienced the moment that he touched that crystal, so he couldn't entirely be blamed...
Well, either way, trying to act as though the past few minutes never happened wasn't going to get him anywhere. Not to mention, people were essentially microbes to him now, so it wasn't like there was even any point to trying to communicate with them. No matter what he did now, he was inevitable going to cause them pain and destruction just by existing.
In other words, he was effectively cut off from humanity altogether, completely and utterly alone as the largest living thing in all of existence.
...he guessed the only option he really had at this point was to try to have some fun with the city, even if it was proving to be really disappointing. Then... well, maybe he could walk off towards the mountains and rest there for a while as the military attempted to attack him. They were welcome to try and give him what he deserved, of course, but somehow, he had a feeling that their efforts were destined for failure. Since he knew there was no chance of them posing even the illusion of a threat, maybe he could try saving them from themselves instead - given his size, he was bound to accidentally down a platoon or two without even trying, so that might be interesting enough as a challenge.
After that, well... he didn't know, really. Hopefully he found a way to shrink down eventually so that he could really do some rampaging. Otherwise, he had nothing left to his name other than the blue briefs that somehow grew with him, so maybe he could claim all of Japan as his own personal island? That would be nice - he didn't exactly have many options when it came to shelter, so he needed all the space he could get.
Now that Mako had come down from the initial high of being miles tall, he was starting to realize just how screwed he was. He wasn't sure how he was going to live life without a bed, or loving parents, or a tv, or any of the things that he had taken for granted, but if this was going to be the rest of his life, then he needed to be prepared to be committed to his new calling as a living natural disaster.
Now then, Mako figured that he might as well...
