Alpha-Gel is a substance used by Statesman that can protect the brain from a headshot wound. After the Alpha-Gel is applied, the agent is brought back to the laboratory, where nanites are used to repair tissue damage in the brain.
Ginger Ale said that upon applying the Alpha-Gel to an individual, they would suffer from severe amnesia and short-term memory loss. They were able to recover their memory if they were to remember a traumatic event in their life; in the case of Harry Heart, he was placed in a situation that reminded him of his shooting of his Cairn Terrier Mr. Pickle. In the case of Agent Whiskey, he was shown a photograph of deceased wife, causing him to remember her death.
