Crossovers that shoould be: beginings of Sub Genius

[Necratoid]

Basically seen it in a Cluster Cross, only it was more complex and not Harry specifically with the powers.  Simplifying down to a simple single cross doesn't change all that much of the effects of the powers themselves, given slow build up due to age.  The real issue with Harry Potter and that as a single crossover is the steep power curve between the series.  Tossing power curve from first year wizard vs planet/ continent/ city crusher is a bit much... Harry being raised at that shrine won't change Washu's interactions all that much from Wld Magic... You only really have three options for a straight crossover type story... 1) Harry (and/or his family) curb stomping things, 2) power levels get out of hand quickly to the point of Masu!Harry's magic is an after though, 3) Harry goes for his own personal veil of silence on his powers and goes all special ops agent H on things.
