Well, this is it, the final fight against Cyrus in Platinum, and he's gotten quite a bit more challenging since the days of Diamond and Pearl. Not only that, but a lot more dramatic, too! His Pokemon are between levels 45 and 48 and they pack a mighty punch. Be extra careful when fighting him! Then be sure to prepare yourself to take on Giratina itself after the fight! (Not immediately after and your Pokemon will be healed afterwards, don't worry.)
