Another significant chapter in Simons' career was her four-fight series against Tina Chiari between 1977 and 1979.

Their first meeting occurred in Weilheim, Germany, in May 1977. After a grueling, back-and-forth war of attrition that pushed both fighters to their absolute limits, Simons outlasted Ranke to claim a knockout victory in the 7th round. Angie Simons vs. Tina Chiari

Angie Simons' career stands as a fascinating historical footnote in the evolution of women's combat sports. Though LGIS operated outside the realm of sanctioned, mainstream sports, athletes like Simons demonstrated the grit, conditioning, and competitive spirit that would later pave the way for the professionalization of modern women's boxing and mixed martial arts.

Simons dominated their first encounter, knocking out Chiari in the second round.

Bouts often featured unlimited rounds or were scheduled to last until one fighter could no longer continue, creating an environment that demanded extreme endurance.

The rivalry between Angie Simons and Heidi Ranke is widely considered the most brutal in LGIS history.
