Falling in love
Z'Reg is a Skrull operative who was sent to spy on the Avengers after his training. However, he arrives on Earth shortly after the Avengers disbanded. Falling in love with the planet's customs and superheroes under the civilian identity of Aubrey Thompson, Z'Reg decides to become a superhero and calls himself the Crusader (a name he chose specifically because it gives no clue as to his abilities).
