Who are the earliest unlockable characters that will give me all the exploration powers in LEGO Harry Potter 2?

Question

Which unlockable characters in LEGO Harry Potter Years 5-7 are the earliest unlocks for all the exploration powers (such as Dark Wizard)?

Answer

• Strength - Dudley: Year 1 level 1. Alternatively, use the super-strength red brick found in Hogwarts.
• Dark Magic - Bellatrix (Azkaban): Year 7 part 2, in the air over the field near Hagrid's house. Use the pink platform with Hermione to get the pumpkincopter, then use it to fly around and get Bellatrix.
• Key - Mrs. Cole: Year 7 part 2. Use dark magic in the diner kitchen to unlock her.
