Krislok


 * Krislok used the alias of Oscar. For other individuals named Oscar, see Oscar.

Krislok was a Graske who enountered Sarah Jane Smith and her friends. He was forced to act as an accomplice of the Trickster.

Profile
The Trickster rescued Krislok from his spacecraft, which had begun to burn up, in return for which, Krislok worked for Trickster as a slave. (SJA: The Temptation of Sarah Jane Smith) Under the Trickster's orders, he first attempted to erase Maria Jackson (who had been protected from the Trickster by the Verron soothsayer's puzzle box) from time by kidnapping her and stopping her from ever existing, although the process went slightly wrong and she briefly ended up in 1964 before being recaptured. It is later sent after her father, Alan Jackson, although he managed to tie it up and forced he to reveal how to put Maria 'back in time' and rescue her from limbo. It later manages to free itself and teleports away. (SJA: Whatever Happened to Sarah Jane?)

While still working for the Trickster, Krislok posed as "Oscar" in order to lure Sarah Jane to 1951 - to go into a time fissure just prior to her parents' death in order that she would try to change it. After the Trickster was successful in creating an alternate timeline where he manifested corporeally on Earth in 1951, the present day was a desolate wasteland where the Graske enslaved the few surviving Humans to mine for resources so he can extend his reach to other planets. The Graske re-opened the time fissure to allow Rani to tell Sarah Jane where the Trickster was set to manifest. (Clyde remained behind guarded by the Graske.) After the timeline was restored and the Trickster defeated, Clyde gave the Graske the box to protect him should the Trickster ever return and seek to punish him. (SJA: The Temptation of Sarah Jane Smith)
