Shaderu is a Ghost Normal type Pokémon with the ability Levitate. It is a ball of darkness with an outstretched hand. It is genderless and defeating it will yield 2 Attack EVs and 1 Special Defense EV. It cannot breed. Shaderu is a recolored Gastly sprite with one of Haunter's hands added in.
Type: BLACK DOOM Color: Black Height: 3.0m or 9'10" Weight: 0.1 kg or 0.2 lbs.
Legend states that SHADERU is invisible. This is incorrect, of course - all it does is shroud itself in a dark cloud made of the burned souls of a thousand unborn children.
Like Turmur, Shaderu has a specific and lengthy task. You have to go around Hoenn and collect a TOTAL of 50 Broken Hearts. Once all 50 are in your possession, go to the Berry Master. He will give you a Spatial Pass. Take this pass to the second floor of the Slateport Museum and go to the top cylander exhibit to encounter Shaderu.
