Teknall:
Engineer. What sort of engineer? All of them.
Passionate science educator. Founder of a global science education not-for-profit bringing technology to disadvantaged regions.
Every room in his house has been adapted into a workspace, and is covered in either his inventions or designs for his inventions.
Mildly paranoid with an inferiority complex, so owns home-built arsenal with enough firepower to make a Texan jealous.
Owns a mansion which he built as an investment property, although the current tenants are some kind of street vigilante group.
Teaches hobo-artists how to do 'chemistry' over 4chan.

Daughter Kinesis is a freelance mechanic and hippie on a perpetual gap year.
Goliath is a home security system Teknall pieced together from military grade technology and he tinkers with it in his spare time, although it's currently tasked with weeding the local park.
Gerrik is Teknall's apprentice and is now the director of aforementioned science education not-for-profit.
