(Shiganshina Arc AU)

Erwin is a main protagonist from the series Attack on Titan. This variation is from the events of the decisive battle for Shiganshina leading to the choice given to captain Levi to save either Armin or Erwin using a titan serum, resulting in the latter gaining the power of the Colossal titan. His role is the commander of the Survey Corps which he aspired to become initially after being inspired by his father at a young age to learn what existed on the outside world beyond the looming threat of the titans. Now as commander he led many expeditions in dealing with the titan threats alongside Levi and other strong soldiers, however it also resulted in casualties. Now his latest expedition sees his regiment successfully reclaiming wall Maria from the titans..but at a high cost however.

Erwin is a rather tall man with a fit body build, short blonde hair which is brown above the ears and also has blue eyes. While he once lost a right arm during a prior expedition in saving Eren, he regenerated it upon gaining the Colossal's power.

As an Eldian who is capable of becoming a titan, he originally didn't possess one but in this AU he now has the Colossal which is a 60 meter tall titan with exposed muscle tissue. He also has natural skills in combat due to his training in becoming the Survey Corps commander.
