OotP’s final duel between Dumbledore and Tom sets the standard for what two powerhouse characters are capable of when set against one another. We are not only treated to a spectacle of high-powered magic but also the awe of knowing anything and everything is possible between the two of them.

In seeing these two duel, we’re able to take note of their style and preferences. Dumbledore is more of a defensive fighter, preferring not to try to kill Tom but, presumably, to nullify him in some way. His attacks center more on natural elements (e.g., the fire whip or encasing Tom in water). This shows how Dumbledore is more grounded and connected with the natural world than Tom is. We also see him being more resourceful in his use of the statues as his helpers and protectors than Tom, who chooses to fight alone.

Tom takes the offensive, preferring to stay on the attack whenever possible. He manages to cast a handful of Killing Curses at Dumbledore and Harry (each blocked by statues or Fawkes), but continues to try to wear down his opponents’ defenses, hoping to catch a slip in their armor. He’s also incredibly resourceful: When Dumbledore tries to wrap him in a fiery, whiplike attack, Tom transforms the whip into a snake to strike Dumbledore at the most opportune moment. He makes a few defensive maneuvers, switching his position around the battlefield to gain advantage and also summoning forth a silver shield that produces a chilling gonglike note when hit. This shows Tom is entirely aware of the threat of Dumbledore and that he must make sure to guard himself as much as possible while still attempting to dispatch him.
