(Non-glitch) You can beat Pokémon League w/solely July '98 University Magikarp (no items in battle)
Notes: This is a rare case where I upload a non-glitch, curiosity, or unused content video but as I thought it was unique I decided to do it.
Since the Japan-only University event Magikarp (of which only 20 exist see https://bulbapedia.bulbagarden.net/wiki/List_of_Japanese_event_Pok%C3%A9mon_distributions_in_Generation_I#University_Magikarp ) knows Dragon Rage, it can even beat Agatha without glitches (where normally since Struggle functions like a Normal-type move in this game, it couldn't touch the Ghost-type Pokémon otherwise).
With enough luck too, you can beat the entire Pokémon League with just that one Magikarp; using the few PP restore/raising items to aid you out of battle and several Potions/Full Restores. In this video given how rare the Magikarp is, I cheated to get it; then raised it to Level 100. Note that it could have the wrong OT/ID, because Bulbapedia didn't have it documented. The DVs of the Magikarp I used are random, but all of its stat experience points ('EVs') are maxed out.
