Generation IV takes place in the Sinnoh Region and that means it has its set of 8 Gym Leaders. However, there are the Diamond and Pearl games and the Platinum game. While the Sinnoh Gym Leaders are the same for these games, the order that they appear in is jumbled.
In Platinum, Fantina appears third while in Diamond and Pearl, she appears as the fifth Gym Leader.

The order is minor because the Leaders will also have different Pokemon in these games. They are the same for Diamond and Pearl but Platinum has its own set of Pokemon. The other thing is that the Gym Leaders in Platinum can be fought in a rematch.
They also have a larger and stronger Pokemon team during the rematch. Don’t worry, we’ll include all the data you need for all these games with rematch included.

In Closing
These are the Sinnoh Gym Leaders that you will encounter when you play the Gen 4 games. Remember that their Pokemon teams will vary per Diamond and Pearl or Platinum. Plus, in Platinum, they have another team when you choose to have a rematch with them.
The Leaders will maintain their specialty regardless but some of them will have an odd Pokemon on their team. Regardless, now that you have an idea of their team and capabilities, you can plan ahead and compose a team and teach the right Moves to your Pokemon to easily beat them.
