Thanks for the input.
All: I fully agree that this Template is not for all games, but in a world where Faeries, wizards, shapechangers, etc are real...well, we have folks in this world who try to play superhero. Nobody'd try this in Harry's world? Not for all games, but certainly possible.
GryMor: Emissary of Power is beholden to someone else for their power. Focused Practitioner is limited to Channeling and/or Ritual. The Scion is not so much a template as a concept with some suggestions. It also doesn't exactly fit the why and wherefore of how this type of character gets their powers. A Scion is the offspring of a human and something else. The idea behind this new Template is to allow a character that has things like Inhuman or Supernatural <ability> or a person to whom literally blending in the shadows or climbing up walls is innate to themselves. These things can be done as a Stunt or high Skill, but are also available as a Power. The Stunts are cheaper, but the Powers are less fallible.
Nick & Ghsdkgb: good points, but they have their own drawbacks.
Ghsdkgb: The upper limit on Refresh spent on initial powers is the Template's drawback. An Emissary of Power has the drawback of being reliant on a superior's good will. The Costumed Vigilante (super powered individual) Template's drawback is a restriction on the amount of initial powers. I went with -6 as an arbitrary limit that allowed a lot of interesting combinations. The -6 limit applies to Powers only, the character can still spend up to their full Refresh limit on Stunts. That being said, the -6 Refresh limit on Powers can be adjusted up or down by the GM to fit the needs of their game. A Minor Talent Template character only allows a max of -2 Refresh spent on a smaller list of Powers, so I figured I had to give the new Template some kind of restriction.
San: PS: I like your idea of no Templates.
