Katrina "Dyna" Armstrong

Katrina Armstrong, better known by her persona Dyna, is a Turf War player and an elite Ranked player in the Ink Sports League. She is the younger sister of Nathan and Bryce Armstrong.

Katrina was born in the Cephalo County, but her family moved to Inkopolis only a year later. While she uses the Sloshing Machine, she primarily uses the Dynamo Roller family of weapons, especially under her Dyna persona. Excessive training with the weapon has given her incredible strength that makes her capable of swinging the roller at the speed of normal rollers. She is the record holder of the Most Splats in a Single ISL Season, a record that Petra Yeager is attempting to break. Despite being offered several times, Katrina is not part of any team.
