Portals 2: A Thief's Curse

Thanks to Desiree's power, the world had forgotten Danny Fenton again. The worst of Danny's woes involved the typical ghost attacks that plagued Amity Park and finding a home for a certain rehabilitated future version of himself.
Until the Guys in White rip a hole in the sky.
The massive portal is leaking prisoners and prison guards alike into the city. More importantly, when the portal destroyed Walker's prison, it had set free a dangerous captive from the era of Pariah Dark. One now loose in the city, hunting a certain half-ghost.
Danny is overwhelmed, his powers useless. His only option is to contact the one hero he knows that doesn't rely on ghost powers: a certain 800 year old ninja.

Back by popular demand. I own nothing but the plot. I'm a huge fan of both series and I grew up with Danny Phantom. Vote and comment, please. If this gets enough attention the series may come back for a season 4 of DP. Butch Hartman has been fighting for it for years and I think it's beyond time for Danny to get a little love.
