I will omit Battles Against Legendaries and only aginst people.
The question is not what battle was the hardest or easy, but with Six Generation of Pokemon Games, what is the greatest Pokemon Battle in the Games?
The battle that has stuck in your mind for years or decades and millions of fans? The battle you remember fighting with sweaty fingers and a sweat down your forehead, mesmirzed by the background music score.
To me even though it is not a hard battle but the answer is simple, the Battle of Mt. Silver.
Playing the old games I heard about this famous battle from my older cousins. After fighting 16 Gym Leaders, the Elite Four and Team Rocket you are brought to a place with high level pokemon. Then as you reach the top of the Mountain you see this solitary figure standing on top of ledge and you wonder who it is. Then he says nothing apart from '..." and the epic music plays and you see...
Its your character from Pokemon Red and Blue!! and in the first time in the games series you see a pokemon trainer with such high level pokemon.
If you are caught unaware it is hard battle as his pokemon are pretty strong but if you are aware it is an decent battle but it is still a challenege. It is a battle that even after so many years has stuck in my mind.
What do you think is the greatest Pokemon Battle in the Video Games?
