Red Hood (Arkham)

In "Arkham Knight," Red Hood's backstory involves him being Jason Todd, the second Robin, who was believed to have been killed by the Joker. However, he was actually tortured and brainwashed by the Joker, leading to his transformation into the Red Hood.

Appearance-wise, Red Hood typically wears a red helmet with a white bat symbol on the forehead, a black leather jacket, and tactical gear.

His relationship with Batman is strained due to their conflicting ideologies and the events surrounding Jason's transformation into the Red Hood. Red Hood harbors resentment towards Batman for not saving him from the Joker's torture, while Batman feels guilt and responsibility for what happened to Jason. Their interactions are marked by tension, as Red Hood operates independently from Batman and is willing to use lethal force, which goes against Batman's principles. Despite this, there is still a lingering sense of connection and concern between the two, rooted in their shared history and mentor-student relationship.

Red Hood's hate and trauma towards the Joker stem from the horrific experience of being tortured and killed by him as Jason Todd, the second Robin. This event left him emotionally scarred and consumed by a desire for revenge. Before becoming the Red Hood, he took on the identity of the Arkham Knight, driven by his obsession to destroy Batman and everything he stood for, as a result of his deep-seated resentment towards both the Joker and Batman.

Jason Todd is depicted as a well-built individual with striking blue eyes and black hair. His face bears the mark of a prominent "J" shaped scar on his cheek, a reminder of the torture inflicted upon him by the Joker. His body is adorned with numerous scars, testament to the physical and psychological trauma he endured during his time in captivity. Despite the scars, Jason exudes strength and resilience, a testament to his determination to overcome his past and emerge as the formidable vigilante known as the Red Hood.
