She beat Heidi Christenson in an MMA match. Sent Heidi from 4-0 (4 finished, 3 submissions 1 KO) to a 4-1 record. There was a thing where it wasn't entirely clear if Heidi was really that good or if she was beating tin cans. Regardless, Astrid took her deadly seriously and beat her in the second round via guillotine choke submission.

Heidi kicked her brains out from behind while her hand was being raised.

Astrid's feelings on the incident were that she was going to make use of it. And because the incident got Heidi kicked out of combat sports as a competitor, Heidi consented to train Astrid as a pro wrestler.

Now Astrid is in ICW.
