(side note: this is just normal Ryu and normal Lucario. No Evil Ryu, no power of nothingness, no Mega Evolutions, just normal, as they come Ryu and Lucario. And this Lucario is wild, just so you all know, so no rage about needing a trainer and stuff, okay?)
Ryu was walking through the forest as he normally does, when he heard noises that sounded like Blanka in the midst of a battle. "Blanka?" He asked, rushing ahead.
He went ahead and saw it was indeed Blanka, fighting against a creature he had never seen before. It walked on two legs, resembled some sort of wolf, had spikes on the back of its paws and on its chest and had a powerful aura surrounding it. Ryu was more than intrigued as he continued to watch the fight which, from the look of Blanka, he was on the losing side of. The strange creature rushed forward at great speeds and slammed into Blanka, causing him to roll backwards a good distance. "Not good enough!" The man-beast snapped, rolling through the air as an electric ball.
"Lucario!" The creature snapped, pulling its hands back, a blue energy forming in between its paws.
At this Ryu was shocked. (Could it be?! Is that creature using the Hadoken technique?!) He asked himself in his head.
"Cario!" It shouted, firing the aura sphere at Blanka as the man-beast rolled through the air in such a way that his face was greeted by the energy blast, blasting him back with a howl as he hit the ground unconscious. "Cario..." It huffed, then turned to Ryu as it sensed his aura, looking at him cautiously.
He knelt down to look it in the eye level, as it was not very tall. "That was an impressive fight. What's your name?" He asked.
"Lucario." It said with the slightest hint of a nod as it looked at him.
"That last attack of yours was very interesting. Do you mind showing it to me again?" He asked, tossing away his traveling pack (in all seriousness, does anyone know what that's for?) and backing up a few feet, getting into his fighting stance.
"Cario..." Lucario said, somewhat puzzled and intrigued by this human, but nodded and took its own fighting stance.
"Fight!" Ryu said, rushing in.

"Cario!" It agreed, starting off with Quick Attack (note: I'm using Lucario's starting moves for this fight. Go to the Bulbapedia or something to learn what its starting moves are. Go the the link that says "Learnset" then the moves will just say "start"), moving quicker than Ryu expected, slamming into him and staggering him a bit, but he quickly recovered.
"Not bad." He said, stepping back again and pulling his hands back. "Hadoken!" He shouted, firing his energy blast at the small blue Pokemon.
"Lucar!" It said, shocked, jumping back to avoid the blast, as he was previously close and wouldn't have had time to attack if he tried from that position, then fired his own blue energy blast, the two cancelling each other out.
"Interesting. You know the Hadoken technique as well." Ryu said stepping out of fighting stance for a moment.
"Lucario." It said, shaking its head, as it knew that was not the name of its attack, but obviously the human didn't know that and Lucario could tell him.
"Well then, let's see what else you can do!" Ryu said, taking his stance again briefly before executing the Tatsumaki Senpukyaku.
Lucario was shocked and caught off-guard at this, as it had never seen a human do that before and consequently was hit by the attack, getting thrown back a bit, but landed on its feet and skidded safely to a stop, not having taken too much damage. At the same time, Ryu felt some minor pain in the back of his heel/ankle area where he had landed the kick on Lucario, feeling as if he had kicked a car. (What is this creature? It felt like metal when I kicked it...) He thought to himself. Lucario clearly saw that its opponent was distracted and used this to its advantage, holding its arms out at its sides, revealing claws that began to glow and became sleek and steel-like. It then rushed in just as Ryu came out of his train of thought and was cut and hit with the powerful attack, seething in pain and jumping back, growling in pain and mentally slapping himself. (I got careless. Need to stay focused.) He said, adopting his stance again. He then rushed in again and throwing a volley of low attacks at Lucario, who managed to keep dodging them and again struck back with Metal Claw. Ryu managed to step back and dodge this, using one of his own special moves.
"Shoryuken!" He shouted, doing the mighty uppercut, catching Lucario under the jaw and launching it into the air. Ryu landed first and spun around to see where Lucario would land and pulled his hands back. "Hadoken!" He shouted, firing the energy blast at the descending Pokemon, blasting it backwards, causing it to roll across the ground before getting into a crouched position. "Can you stand up after that?" He asked.
"Cario!" It said, jumping back onto its feet and rushing in with Metal Claw again.
"You're using the same move too often! It's getting predictable!" Ryu said, executing one of his super moves. "Shinku... Hadoken!" He shouted, firing the next level of his attack at his opponet.
"Lucario!" It smirked. It had predicted this and made a plan in advance. As Ryu fired this technique, Lucario used detect to avoid the move within inches of getting hit.
"What?!" Ryu asked, shocked. Lucario then followed this up with Extreme Speed, rushing at Ryu with speeds faster than he could react to, slamming into the wandering warrior and sending him back, tumbling across he ground before her got back to his feet. Both had visibly taken damage and were wearing down, but both were capable of continuing. "I think it's time we bring this to a close!" Ryu said.
"Lu!" Lucario agreed. The two rushed in again and Ryu decided for another powerful attack.
"Shinku... Tatsumaki senpukyaku!" He shouted, executing his most powerful physical attack on the Pokemon.
"Lucario!" It said, using detect once again to avoid the attack and decided to use its ultimate physical attack, focusing on all of its physical strength and unleashing a devastating combo on its human opponent with Close Combat.
Ryu let out many grunts and shouts of pain as he was pummeled with force that matched his own and was staggered back, dropping down on one knee in exhaustion and to take in his sudden pain and injuries as Lucario panted heavily and looked as if it was also recovering from great physical exertion. "What incredible power! To think something that small could pack so much of a punch." Ryu said, struggling to get up and managed to bring himself to his feet, but that took a good amount of energy and he had to pause both from pain and to massage his knees, which were slightly buckling under pressure. Lucario finally recovered and saw this as an opening to end the fight.
"Lucario!" It shouted, rushing in with an aura sphere prepared, jumping up and blasting the attack point blank into Ryu's face, knocking the wandering warrior down once again and Lucario to do a flip in mid-air and drop onto one knee from fatigue upon landing.
Ryu groaned and got up into a sitting position, looking at his victorious former opponent. "That was a great fight. Looks like I still have a long way to go. You've got great potential and some impressive moves." Ryu said as he tried getting up again, Lucario walking over and helping him up, also offering him his traveling pack. "Thank you, my friend. Perhaps we'll see each other again someday." Ryu said as he started walking, only to find that Lucario was walking alongside him, looking at him with a smile. "So, you want to come along?" Ryu asked, returning its smile.
"Lucario." It said with a nod.
Ryu smiled and chuckled at this. "It does get lonely traveling by yourself out here. Welcome to the party, Lucario." Ryu said as they continued to walk.
Reasons for the outcome:
1: Lucario's natural aura is incredibly powerful and may even be on par with Ryu's. So its aura sphere is likely as strong as one of Ryu's Hadokens.
2: Lucario being a Steel/Fighting type plays out well for itself, as Ryu hitting it without an area with padding (not punching it) would hurt as if he just hit something made out of metal, while Lucario would take relatively little damage.
3: Contrary to the game, detect has been shown to allow the user to dodge enemy attacks as much as they want without fail, allowing it to dodge most of Ryu's attacks with ease.
4: Quick Attack would likely trip up Ryu, but Extreme Speed, which is like Quick Attack times 2, would be too much for him to handle and react to before he is hit.
5: Lucario's smaller size A: makes it faster and B: makes it a much more difficult target for Ryu to hit. For those of you who had a younger sibling, picture how hard it was to fight them when they were so much smaller and moving around a lot. You'd have to bend over or crouch down to be able to punch them and a lot of the time they were too fast for kicks as well. Basically the same thing, Ryu would have trouble hitting it without hurting himself and then level changes (attacking low, then high, them middle, etc.) would be near impossible.
6: This was more of a friendly spar than an actual fight compared to the last 2, so they weren't actually trying to hurt each other, so that's why this was relatively less all-out than the others.
7: Close Combat would be the thing that wears them both out, as Ryu would taken absolutely staggering damage while Lucario gets severely worn out by the attack, making the next attack most likely the last by either one.
