sorry it took so long here it is though!
Ghostly Wail

The ghostly wail is beyond my knowledge. The only people ive known to master it are Danny Phantom and Dan Phantom (their differences are age wise and good and evil). Ghostly wail can breakdown buildings and destroy peoples voices. When using ghostly wail it is known that your powers can short out and you will turn back into human form. Obviously it is very hard to master so it may take a few years.

Please send in more Phantom bios to my email
