Name: Agatha Heterodyne
Age: Approx 22
Species: Human
Gender: Female
Personality: 
On the whole Agatha is kind, persistent and brave. Eager to jump into new situations and often impulsive. However she's also quite jaded to the strange things in the world. She also has a spark side, almost a seperate personality that activates when she's exposed to any thinking problem, or advanced science. This personality is ruthlessly curious and obsessed with the creation of new scientific wonders, for no other purpose than to bring them into existence. This obsession bleeds into her normal character, and leads to a general 'science is fun because EXPLOSIONS' attitude, one shared by most of her family. However, despite this rather explosive quirk, she's amiable enough, and tends to work to improve the lives of those around her (even through some fairly bizarre means).
Bio: 
Agatha Heterodyne is the unrecognized heir of the Heterodyne family, the most feared family of sparks in the world. Her family burned the world to the ground, only to build it back up again, and carry the most powerful 'gift' ever found. However, her gifts were suppressed at a young age by her adoptive parents in order to hide her from the eyes of the world. To this purpose she was granted an amulet that suppressed her 'spark' side, and allowed her to live a relatively normal side. Unfortunately she was eventually discovered, which set into motion a political motion that ended in a cataclysmic war for Mechanicsburg, home of the Heterodyne Family, and the revival of the Other, the greatest evil the world has ever faced. Now Mechanicsburg has been frozen in a spacetime bubble, the other has possessed a host of mechanical bodies across the world, and the current leader of the Empire has been possessed by his own father. And amidst all of this, Agatha Heterodyne is attempting to put everything back the way it belongs, with minimal casualties.
Abilities:
Agatha is a Spark, the very textbook definition of a mad scientist. Her intelligence is practically limitless, and she's able to invent entire new branches of science on the spot. She can create an army of robots from scraps, build a death ray from spare parts, and is able to instantly recognize and understand almost any technology she comes into contact with. The machines she has created are amongst the most dangerous on the planet, and are capable of intercontinental destruction. She has created unstoppable death machines in her sleep, and has done so much worse while awake.

She's also an incredibly skilled hand to hand fighter, having been trained by the warrior princess Zeetha. She is physically highly capable, both in strength and speed, although still easily within human limits.
