Timekeeper

The Timekeeper is the main antagonist turned anti-hero in the film, Spy Kids 4: All Time in the World. He was a villain who seeks to stop time in the world because people have been wasting time and vows to take away time from the world.

Origin
Back in the 1930s, the Timekeeper's scientist father brought him to a laboratory where his father and his co-workers were conducting a experiment on time travel called Project Armageddon. His father told him not play and wander in the lab, but he did not listen and he was caught up in his father's experiment and frozen in time. His father had not yet found a way to unfreeze him in time until he died due to old age. One day, a group of scientists found a substance from a meteorite known as the Chrono Sapphire, which has special qualities, including the ability to unfreeze the Timekeeper in time. When the Timekeeper was unfrozen, he realized that all people he knew and loved already passed away. Under the name Danger D'amo (most probably not his real name), he became the head of the OSS, a spy organization.

Motives and Scheme
When the Timekeeper first appeared to the media as a villain, he stated that his goal is cause Armageddon by stopping time. He believes that people does not value time, but waste it. In order to do this, he must activate the Armageddon device. He leads a bunch of masked minions under the command of his trusted henchman Tick Tock to achieve his goal.

However, the real purpose of the Armageddon device is not to stop time, but for him go back in time. The Timekeeper longs to reunite with his father and to prevent his death. He already went back in time more than once, but failed and created multiple versions of himself, which served as his minions (including Tick Tock). He finally suceeds, probably because the Chrono Sapphire went along with him through the time portal created by his Armageddon device. He reapperaed immediately where the portal once were but reapperaed as an age-readjusted version of himself, telling Cecil and Rebecca that they are right, that he can't change the past and that his father is still dead. He told them that people should not live in the past but live a life moving forwards to the future.
