The Infimatrix is the first episode of Fred 40.
The episode starts with a space battle. A smaller ship is being blasted by a large,orange one, piloted by Vilgax. The smaller ship ejects a pod towards Earth, and causes an explosion. This causes Vilgax horrible injuries.
On Earth, a 10 year old boy named, Fred finishes school for the summer holidays.Fred wanders off into the forest in anger after an argument with Jen,his cousin (she hopes he gets eaten by a bear) and he notices a shooting star. The star is actually the pod jettisoned at the start. It hones in on Fred (In later episodes, it shows that since the pod and the object inside are able to hone on all Plumbers, the pod actually sensed grandpa's DNA, but gets the wrong parson. It does the same to Jen and grandpa in another episode) and he just barely jumps out of the way before it hits. He slips into the crater it created. The pod opens to reveal a watch like object; the Infimatrix. It latches itself onto Fred's wrist (again, because of the DNA), scaring him. After several failed attempts to get it off, the faceplate pops up and shows the silhouette of an alien. Thinking this is cool, he pushes the faceplate back down, and transforms into Boulder. He screams and runs around in a panic, terrified because he's covered with rocks, but realizes that he isn't getting hurt, and decides to test his power out, creating several landslides at the ground and causing an earthquake.
Grandpa and Jen notice the earthquake Jen is naturally terrified at his appearance and, just as he is trying to reason with her, whacks him and tells him to stay down. Jen asks what happened, and Fred tells the whole story in a matter of seconds, finishing just as grandpa appears. They reveal what happened to Fred, and is just about to tell the whole story to grandpa again, but Jen interrupts and reminds them of the earthquake. Grandpa tells Fred to cover the cracks stones.
Back on Vilgax's ship, he is fairly torn up, on life support in a large tank with his legs and left arm missing. He sends two of his drones down to Earth in order to retrieve the Infimatrix.
Meanwhile, back on Earth, Fred, Jen, and grandpa are at a campfire, talking about the watch.
