His real name IS Thomas trumper Kaulitz. EDIT: He said in multiple interviews that neither he nor Bill had extended names, and had never had. Their names are NOT Thomas or Wilhem, they are Bill and Tom, end of discussion. As for the Trümper, that is only their stepfather's middle name, and the twins decided to get it removed, they didn't want to have the Trümper name. Tom Kaulitz, is Tom Kaulitz's real name, nothing further, nothing less.
