Feck it, I'll try! I'm just gonna have fun with it, rather than worry about having a hard challenge.

Partner Pokemon: Magmortar (start with Magby)
Challenge: Single
Game: Pokemon Red++ Hard Version (Mateo's Red hack)
NOTE: To get the Pokemon I wanted, I used the Wonder Trade feature (traded away my starter) until I received a Magby.
=========================
So I started with Squirtle because its the bulkiest, therefore the easiest to win the rival match... also, the Rival would have Bulbasaur which would make things easier. I fetched the package from the Mart, got the Pokedex, then caught a Rattata so I can trade my starter away - as the Wonder Trade works by giving you a Pokemon of level equal to the one you traded away, and I wanted to get a level 8 Pokemon and not a level 3. Then I repeatedly traded the received Pokemon until I received Magby.
Phew! Now that that's out of the way... I went to Route 1 and caught a Pidgey, which will be my Fly slave, then went to pick up a Meowth from Route 22, which can learn both Cut and Flash. After grinding to level 11, the Rival appeared!
RIVAL BATTLE (ROUTE 22):
Eevee (Lvl 10) was first out. After a smokescreen, I pounded on it with Ember until it fainted; Eevee never landed a hit. A level 9 Rattata was sent out, which fell much faster. A level 11 Pidgey's Sand Attack made defeating it a struggle, and a couple of Gusts forced me to use a Potion, but I landed 2 Embers and it was down; Magby then leveled up to Lvl 12 and learned Faint Attack. Finally, a level 12 Bulbasaur came out; Magby's low Defense meant even Vine Whipe was hurting a bit, and I only hit one Ember out of 4 uses before I was forced to use my last Potion. I gave up on landing another Ember and used 2 Faint Attacks to finish it off; thankfully, Magby's Attack is about as good as his Special, so it was a clean 2 hits from ~50% HP... so Magby won, with 3 HP left.
After scurrying to the Pokecentre and stocking up on Potions and Antidotes, I blitzed through Viridian Forest and BURNED THE WHOLE PLACE TO THE GROUND-- Okay, I just killed a hundred bugs; I also learned Fire Spin, which could come in handy. I made sure I was level 20 before entering Brock's Gym though... this was not gonna be easy.
I rested at the Pokecentre, walked to the Gym with my held held high, and faced down the Gym trainer, who's level 14 Diglett and Sandshrew were quickly burned to cinders. I walked up to the back wall where Brock was standing, and prepared to fight. "Fine then... Show me your best," he said, and the battle began.
BROCK (PEWTER GYM)
As I sent out Magby, Brock sent out a level 12 Aerodactyl. Smokescreen meant his own attempt to make me miss, Sand Attack, failed, and I proceeded to wail on it with Faint Attack; 3 Faint Attacks was all it took, as Aerodactyl gave up attempting to hit me with the already-inaccurate Rock Tomb and spammed Agility. Omastar (lvl 13) was Brock's next 'mon. After Smokescreening for extra safety, I used Fire Spin which, thansk to its Gen 1 mechanics, stopped him attacking me at all! After getting him down to ~40% HP, I slammed it with a couple of Faint Attacks (while he, of coursed, missed); Magby reached level 21.
Omastar down, Brock seemed dismayed - how could he lose to a baby Fire type?! He sent out his best - a level 15 Kabutops. After hitting Kabutops with a Smokescreen (of course), he responded with a Rock Tomb which blew Magby apart... almost. Down to 3 HP, I panicked and made Magby use another Smokescreen. Brock, seeing victory within his grasp, grinned, commanding Kabutops to use Absorb to finish Magby off... but it only did 1 HP damage. As Magby was still faster than Kabutops, and Magby could not take another Rock Tomb even if I potioned him up, I decided to run with Fire Spin and try and whittle him down. After 9 or 10 turns of keeping KAbutops in fire, unable to move, he finally collapsed. Brock was defeated.
He offered a Boulderbadge and a TM36 (Rock Tomb) from his extended hands. I took it, slightly shaken from Magby's near-defeat. Restoring him at the Pokecentre, I ensured I had the Potions and Repels necessary to get through the approaching hellhole... Mt Moon.
