The pokemon series never revealed this dark secret, there was a deadly cartridge. Pokemon creepy black was the hacked version of fire red and the story of the main character having an unknown ghost pokemon along with the starter. The ghost was invincible….and could kill anything with deadly power. You make it through the whole game actually “killing” these pokemon.
“Defending Pokémon were unable to attack Ghost — it would only say they were too scared to move. When the move “Curse” was used in battle, the screen would cut to black. The cry of the defending Pokémon would be heard, but it was distorted, played at a much lower pitch than normal. The battle screen would then reappear, and the defending Pokémon would be gone. If used in a battle against a trainer, when the Pokéballs representing their Pokemon would appear in the corner, they would have one fewer Pokéball.
This is the reason why the song “Deadly Cartridge” has the creepy vibe to it. The pokemon players anthem and the reason why i enjoy playing it so much
