How to get a level 100 nidoking in pokemon red & blue for the gameboy.
To do the glitch you are going to need to get charmander as your starter. Then you are going to go to Virginian forest. Then get poised by a weedle and be four spots away from the last trainer in the forest. Make your charmander at around 3 hp from poison damage. Save at the 4 spots away from the trainer. You’re going to need some rng here. You’re going to encounter the trainer and get poisoned but encounter a Pokémon that is not from the trainer at the same time. When you encounter the non trainer pokemon, loose the battle. Then when you’re back find a pidgie and use growl at it 6 times(you can use four but there then is no garentie (how ever you spell it) that the glitch will work) after you use growl six times you are going to make the pokemon faint. Make sure you have pokeball's. Then go back to the forest. You will encounter a level 1 nidoking. Capture the nidoking. Then find a level two pidgie or something like that. Almost make it faint with charmander then send out you’re nidoking. Then make the pokemon faint with nidoking. Since the nidoking doesn’t have enough xp to level up, the game will freak out and give you a level 100 nidoking.
