The Wizard (TV series)
Simon McKay is a genius and inventor with dwarfism who chooses to spend his life as a philanthropist and innovative toymaker dedicated to preserving and protecting innocence. CIC agent Alex Jagger is assigned to protect Simon from the evil forces who wish to use Simon's genius for their own nefarious purposes. They are soon joined by Simon's long time friend, Tillie Russell. Simon, Alex, and Tillie become a family unit working together through adventure and adversity, especially when it comes to defeating Simon's self-proclaimed arch-enemy, Troyan, who would rather seek revenge upon the world for his suffering from the radiation poisoning he brought upon himself than take responsibility for his own actions.
