Dr. Ratio is a highly-anticipated upcoming 5-Star character in Honkai Star Rail. This guide will cover everything you need to know about Dr. Ratio, including his release date, abilities, leaks, and more.

Dr. Ratio belongs to the Intelligentsia Guild, a counterpart to the Genius Society that Herta and Screwllum are a part of. He seeks to disperse knowledge throughout the universe to combat ignorance rather than limiting intellect and creativity to a select few.

Dr. Ratio Release Date

Dr. Ratio will debut alongside Honkai Star Rail Version 1.6, which is currently slated to release in early 2024. Before then, the Version 1.5 update will introduce new characters like Huohuo and Argenti.

It’s still unknown whether Dr. Ratio will be featured on the first or second limited banner of Version 1.6, however. Ruan Mei is the other new 5-Star character debuting in Version 1.6 alongside Dr. Ratio, so she may be the better choice for your Stellar Jades if you need an Ice Harmony character instead of an Imaginary character on the Hunt Path.
