There are so many variations on this. I figured the very basic character type is someone organized around a theme, so that often gets called an elemental controller or an energy controller. On the other hand, you could easily say that T'A'Shrin, the humanoid fox stranded on earth (character of a friend of mine) was a basic blaster whenever she had her pistol.
|Blaster (40 point template)|
|Power (whatever that blast is) Expert (+2)|
AddendumReally, this is a versatile character type. I probably haven't narrowed down enough. This one could have lots of different changes rung on it, but as is, it's a good middle-of-the-road character. The character is good with the blaster and dextrous--not smart, but I haven't been concentrating on Intellect for any of these.
You could move that Specialty into Coordination directly.
A trick shooter: The Blast is actually a gun of some kind; swap out Flight for Super-Speed (some kind of vehicle), and change the Force Field to Damage Resistance.
An energy controller might look like this:
|Blaster (Energy Controller Variant) (40 point template)|
|Energy Control (Blast)||5|
|Extra: Reflection (your kind of energy)||5|
|Regeneration (Limit: Source)||5|
(Remember that a Limit gives you the option of raising the level of the power, essentially getting two ranks. That's what I've used here.)
