Hange appears to be an energetic, freethinking researcher with a very unique way of conducting themselves and their work through their rather observant and objective character. Hange explains that when they first joined the Survey Corps, their heart was filled with hatred; until they kicked the head of a 3 meter Titan and were shocked at how abnormally light it was. This drove Hange to forget most of the resentment and insecurity they held onto, and take on a new approach to Titan research.
