FBI Agent Tucker was a character on Beauty & the Beast. He was portrayed by Mark Taylor.
Tucker was the middleman between Vincent Keller and Robert Reynolds, who was trying to get rid of Muirfield by using Vincent to go after all its members and the beasts that were created. He gathered information to relay to Reynolds, and also kept an eye on Vincent. It is assumed he was part of the group that brainwashed Vincent and wiped his memory to program him into a soldier.
Tucker was killed when gathering information on Sebastian Clifton, another beast. He realized Sebastian had noticed him, and tried sending the information to Vincent before Sebastian got to him. Sebastian ambushed him in his car, and tried to get Tucker to give up who he was working with. Tucker refused, and Sebastian punched a hole through his chest, killing Tucker.
