You sure will. That symbol doesn t belong to you and you don t hold the copyright/trademark rights for it.Don t use it. They ll get their lawyers after you.
Disney Corp. now owns DC (Superman, etc).You cannot legally use any trademark, copyright or logo that is owned by another entity. If you do, they will sue you and they will win.Better to be creative and create an original company symbol.
DC Entertainment will not be pleased. Licensing the logo is NOT cheap.
MAJOR copyright violation
