Anything You Can Do... is a science fiction novel by Randal Garrett published in 1963, under the pen-name Darrel T. Langart.
One shipwrecked alien against the power of an entire planet means a losing battle... until Earth builds superman!
An alien crash lands on Earth, and for ten years terrorizes the planet, hiding, periodically killing and eating people and stealing materials for some unknown purpose.
The only hope is Bart Stanton, a medically-engineered superman, designed for the sole purpose of confronting the “Nipe”.
Anything You Can Do… was first serialized in Analog in May and June 1962.
