Almost all information about Hansel is unknown.
Almost nothing is known about who Hansel is/was. Hansel is not even his name, merely a legal alias adopted for ease of reference.
Hansel used to run a highly respected team of heroes in Germany. He was convicted of fraud and money laundering, and perhaps something else...
Whatever the case, he lost in court, and everything was taken from him. His own powers were used to mask his identity, to the extent that he cannot even say his name.
But now Hansel has reappeared and he is determined to reclaim his honor, his identity, and his team.
Whether they want to join him or not.
