Renet Tilly is a Timestress, apprenticed to Lord Simultaneous and an ally of the TMNT.

Mirage Comics


The Life of Renet in the 79th Dimension of Null-Time before her time as a student of Lord Simultaneous, the guardian of time, is not known.

The youthful apprentice of the time lord, Lord Simultaneous. A rather reluctant, spoiled, and impulsive teenager, Renet’s parents, also denizens of the 79th Level, hoped that apprenticing her to Lord Simultaneous would help her develop some kind of common sense. Curious and impatient as she was, she did not care very much for studying. Renet first met the Turtles fooling around, when one day out of boredom she snatched her master's Time Scepter and was caught by him. She replied immediately and time-traveled off with Lord Simultaneous’ Sceptre of the Sands of Time to Earth - more specifically to 1986 New York City. Renet and the Turtles became friends, but Simultaneous appeared and sent Renet into a panic. Fleeing Simultaneous further, she and the Turtles went to 1406 A.D., straight into a castle siege.

The castle belonged to the dark mage Savanti Romero, a former, but exiled student of Simultaneous, and the besiegers were the soldiers of Cerebus, who was after some scrolls, that Romero had stolen. Romero also managed to grab the Time Scepter, and the Turtles and Renet had to contend with Cerebus' help to attack the castle and get the Sceptre back from Savanti Romero. The force was, however, no match for Romero's magic, but before it came to the worst, Simultaneous appeared. Romero attacked Lord Simultaneous who took the Time Scepter again, and cast Savanti into prehistoric times. He handed the scrolls to Cerebus, sent the Turtles back again to their time, and sent Renet to wipe dust in his huge library to. (TMNT Vol. 1, #8).

Later, however, managed Renet to concentrate on her exam, and she gained over time - often with bitter experience - more responsibility for her role and more importance tasks to achieve.

Renet later sent the Turtles a time cube borrowed from Lord Simultaneous. The Turtles, out of curiosity and boredom, used the cube to go on a trip to various eras, including the creation of the universe itself before returning to the present (TMNT Vol. 1, #33).

When the Turtles accepted Savanti’s challenge in the present, Renet appeared and accompanied them to do battle with Savanti Romero in prehistoric times. After defeating him, they were forced to spend several weeks there until they were able to retrieve the Sceptre of Time (Tales of the TMNT #7, Turtle Soup #3 & Shell Shock).

Thousands of years later - according to her personal calendar - a much older Renet, returned as a full-time champion, now the Mistress of Time in Lord Simultaneous’ place after his retirement, came back to give her friends the Turtles’ assistance against Savanti Juliet, who was attempting to exact revenge on the Turtles and their friends, for the apparent death of her husband by their hand. Renet used Juliet’s powers against her, killing her (TMNT Vol. 1, #42).

Renet, somewhat younger than the version of herself that helped them defeat Savanti Juliet but older than the version that accompanied the Turtles to prehistoric times, returned to send and accompany the Turtles to Feudal Japan to stop Savanti Romero’s latest plot of revenge. As Lord Simultaneous had once done, she exiled Savanti back to prehistoric times (TMNT Vol. 1, #46 & 47). In Dark Shadows.

Renet explains that if Raphael proceeds to teach Shadow Jones martial arts, this is the likeliest outcome. If he chooses not to, then the likeliest outcome is that she will be murdered by a Foot Mystic at age 23. Raph doesn’t like either option, and Renet explains that this is the very reason why looking in on your own future is never a good idea. Raph thanks her for the favor anyway, and Renet tells him that she owed him for saving her from a t-rex.

Returning to the present day, Raph finds a goth, teenage Shadow Jones beginning her martial arts training with Casey Jones. Raph knows he can’t talk her out of it, but asks that she call him “Sensei” from now on.

Elsewhere, back at Renet’s place, she’s approached by Lord Simultaneous, who tries to tell her why she should never show other people their futures. Depressed, Renet says she’s figured the lesson out the hard way and will never let herself forget. Renet can be seen watching an blind, elderly Donatello in the Tales of the Teenage Mutant Ninja Turtles TPB frontispieces and epilogue. Don solemnly climbs into bed, completely unaware of Renet’s presence, the Timestress begins to weep. Renet then activates her time scepter and vanishes.

Wiping the tear from her cheek, she reappears in a “better time”, joining all four Turtles, Splinter, Casey and April O'Neil for a picnic.

She was also a guest at Splinter a funeral and later cleared up - though with obvious reluctance - April's true origins.

Tales of TMNT Vol.2 # 71

In the alternative history comic The Paradox of Chudnovsky Renet and Savanti Romero were actually a couple, but their personal differences about the objectives of their studies under Lord Simultaneous ultimately led to their separation. Savanti was not cursed by simultaneous, but physically corrupted by his investigation of the death-time. At the end of their struggle against Savanti, Renet is struck by his charm and her intelligence and mental maturity are restored to the state in which they had been entering the space-time university.

IDW Comics

In the IDW comic series Renet has her debut in a special story, where she "invites" the Turtles to the interdimensional Battle Nexus tournament. In this version she is also Lord Simultaneous' pupil in magic, dimension travel, and apparently his successor in the Dimensional Council.

At the time in which she appears for the first time, the cruel Councilor Nieli hosted a series of merciless gladiator fights, which only he really liked. Renet was also against the games for personal motives, because one of the champions, the warrior Baltizar, had won her heart. For this reason, they brought the Turtles to the hub of the dimensions and helped the culmination of these events to instigate an uprising against Nieli, which meant that Nieli was banished and the games were transformed into a far more peaceful affair.

2003 Series

Renet also appears in the 2003 TV series, along with some minor changes in her backstory. Here Renet is shown to be quite a scatterbrained person who came to her friends with good intentions, but with little practical skill she caused some problems across space and time.

Already in her first appearance Renet was sentenced to dusting in Lord Simultaneous library because she had accidentally reversed the evolution on a planet of giant worms, and got a six-week penalty quickly, she tried to use the Time Scepter to get though her sentence quickly. However, this played into the hands of Savanti Romero, who in where he was sitting, caused the arrival of the scepter with black magic. Again Renet befriends the Turtles, who need to help her with her ​​adventure again and get her out of trouble.

In the 2003 cartoon, the Time Scepter was then stolen by Savanti Romero's pet, which turned out to really be Ultimate Drako- a fusion of the Ultimate Ninja and Drako, both former foes of the Turtles.

Simultaneous later entrusted Renet with the Time Sceptre again, once more dispatching her to defeat Savanti, who now threatened the human race itself. Traveling to the Cretaceous Maastrichtian period with the Turtles, Renet was captured by Romero, who planned to sacrifice her to increase his power. He was defeated by Donatello, and Renet was rescued. However, the Time Sceptre fell into a nearby lake and was lost for three months, until Michelangelo found it in the belly of a massive fish he'd caught for the Turtles' dinner. They were then able to escape the imminent asteroid collision. During the adventure she mentions an adventure she went on with April that hasn't happened to April yet.

Back to the Sewer

Eventually, however Renet came into the final phase of their training. She made a cameo at the end of the seventh season finale, she used the time scepter - apparently with simultaneous' permission to observe Casey and April's wedding and noting how it made her cry no matter how many times she been to it, implying she had visited the scene before.


During the run of the 2003-2009 series, Renet has appeared in 4 episodes.
