Kay Hansen

Hansen returned to Invicta at Invicta FC 31 in September 2018 with an impressive third-round TKO victory over Helen Peralta. After the bout, Hansen called out undefeated flyweight prospect Erin Blanchfield. Hansen would get that fight at the very next event, Invicta FC 32, serving as a late replacement for Luanna Alzuguir and moving up to flyweight. Hansen lost to Erin Blanchfield via majority decision.

Hansen bounced right back at Invicta FC 33 in December 2018, returning to strawweight and defeating Sharon Jacobson with an incredible third round submission, countering Jacobson's attempted belly to belly suplex into an armbar with only 17 seconds left in a fight she was losing on the scorecards. Hansen had taken the fight against Jacobson on one week's notice, replacing Kanako Murata. In May 2019, Hansen lost a split decision to Magdaléna Šormová. In October, Hansen defeated Nicole Caliari via third round submission.

Hansen made her amateur debut in September 2017, less than a month and a half after her 18th birthday. The fight took place under Fight Club OC at their Gladiator MMA Championship Series 3. She fought Cecilia Padilla in the flyweight division and won via technical knockout in the first round.
