He arranged for two of his parolees, Brian Cooney and Dimitri Skontos, to be abducted so that they could be forced to participate in the Löwen Games since they both possessed excellent fighting skills. When he had the two Wesen abducted, he did it in violation of his instructions from Sean Renard. Renard consulted with a mysterious priest, telling the priest that Leo had strayed from the path. After the priest was assured that Leo Taymor could not be reformed and had lost all respect, the priest sadly agreed that he must be dealt with. After Leo escaped the police, Renard found him. Leo threatened him, and Renard walked away, but an unknown, vicious Wesen attacked by surprise. Leo was violently killed in the background. Seemingly, Leo Taymor and Renard had known each other for a very long time, as Renard referred to Leo as a fellow parishioner when discussing him with the mysterious priest.
- His name is a pun on lion tamer, "Leo" meaning lion in Latin and "Taymor" sounding phonetically similar to tamer.
