Some TMNT stuff really isn't for little kids.
In the IDW Comics Simultaneous is a member of the Dimensional Council, the Governing Council of the node of all dimensions (later called the Battle Nexus). Just like his colleagues, he was an opponent of the bloodthirsty, uncompromising gladiator games, which the leader of the council, Councillor Nieli, organized to satisfy his thirst for blood. After Simultaneous' own student Renet whose lover Baltizar and the Ninja Turtles brought excitement to the games and thus their bloodthirsty tradition was put to end, therefore, Simultaneous was called by the Council to be the good will ambassador and patron of the new, more peaceful games, whose foundation the Turtles had encouraged .
As lord of time and space, Simultaneous had control over such powers. The Time Scepter helps him with his powers, such as freezing individuals. He can also transport independently across time and space, including different dimensions and realities.
Personality and traits
Although on the surface stern and grumpy, Simultaneous is basically a compassionate person and a concerned father figure. His feelings, however, are mainly characterized by his responsibility for the maintenance of the time continuum, which can quickly come out of balance by the slightest carelessness. Therefore, he attacks rarely and make things run at the time they prescribe - and perhaps also to give his intractable students now and then a proper lesson in responsibility. For intimidation purposes he often appears as a giant floating head, a method similar to the Wizard of Oz.
Simultaneous, the Time Lord is able to influence the forces required to create space and time according to his will. He can freely travel through time and space and between different realities and look into them in order to observe critical operations. He also possesses some magic or reality-altering powers, which he used primarily when he turned his power-hungry students Savanti Romero into a demonic being. In the comics he used the Digital Cosmic Quartz device - and formed the Time Scepter -; in the 2003 series, however his powers seem to be of a natural/magical origin. How far the powers of Simultaneous really reach, is not precisely known.
- In the RPG - Appendix Transdimensional Teenage Mutant Ninja Turtles, Lord Simultaneous' age is given as 57. He has been at the office of master time for the last 16 years in his first appearance.
