Thanks [MENTION=6792445]famousringo[/MENTION] It's interesting to see what other people would do with their spell selections. Honestly I wouldn't have gone with some of those spells, but that's the whole point of asking.
Anyway, I wondered about a blaster sorcerer, so I came up with this:
Cantrips: Fire Bolt, Light, Mage Hand, Minor Illusion, Prestidigitation, True Strike
Level 1 (4 slots): Burning Hands, Magic Missile
Level 2 (3 slots): Mirror Image, Scorching Ray
Level 3 (3 slots): Counterspell, Fireball, Slow
Level 4 (3 slots): Banishment, Wall of Fire
Level 5 (3 slots): Animate Objects, Hold Monster
Level 6 (2 slot): Sunbeam
Level 7 (2 slot): Fire Storm
Level 8 (1 slot): Incendiary Cloud
Level 9 (1 slot): Meteor Swarm
MetaMagic: Empowered Spell and Quickened Spell. Heightened Spell at 10th and Careful Spell at 14th.
This guy brings the heat! He is a problem solver! Just realize that he believes that no problem can't be solved by a large enough explosion. Indeed, as the size of the explosion goes up, the number of problems it can't solve goes down.
For this I assume a Gold Draconic Sorcerer (Or Brass or Red if you want to pick an inferior dragon type

).
Note that while he is essentially an Arcane Fire Hammer, he is not entirely one note. Counterspell, Slow, Banishment, Animate Objects and Hold Monster give him some flexibility, and Mirror Image gives him some defense.
