Earth-50/Timeline 1

Timeline 1 is the Prime Timeline of Earth-50 and the primary setting of Ben 10: Protector of the Omniverse.

Differences From Canon Timeline

 * Although some key events occurred prior to the events of the original series, the timeline follows the canon timeline more or less until Season 3 of Alien Force, where Vilgax did not return.
 * Due to Vilgax not returning:
 * Ben and Kevin did not hack the Omnitrix.
 * Kevin did not mutate into an amalgam of different materials.
 * Chromastone did not die and was not replaced by Diamondhead. However, Ben did still re-unlock Diamondhead.
 * The Omnitrix did not self-destruct and Ben chose to keep it instead of taking the Ultimatrix.
 * A significant number of episodes and key events from Season 3 of Alien Force and beyond did not happen. The exceptions are stated in the next section.
 * The events of Alien Swarm occur considerably later in this timeline than they do in the canon one.
 * Chimera Sui Generi retain their lore from pop-up trivia revealed in the original series:
 * All female Chimera Sui Generi have a dark "beauty mark" somewhere on their center face tentacle.
 * Most Chimera Sui Generi were trained from birth for combat and crave any chance for it.
 * Primus exists, but the Omnitrixes do not depend on it.
 * Petropia remains destroyed and Sugilite is still deceased.
 * Instead of working on the Omniverse Omnitrix, Azmuth worked on the Infinimatrix.
 * Mr. Baumann does not hold a grudge against Ben for the damages he caused to his shop in the past.
 * Two out of Alien X's three personalities have to agree in order to perform an action, unlike in Omniverse, where all three have to agree.
 * Echo Echo is not made of living sound waves. His containment suit in the canon timeline is his real body in Timeline 1.
 * Jetray cannot travel into hyperspace.
 * Rath is not afraid of water.
 * Encephalonus IV and Anur Phaetos retain their Vilgax Attacks lore. However, unlike in the aforementioned game, Anur Phaetos is a planet instead of an alternate dimension.
 * The rest of the Anur System retains its lore from pop-up trivia revealed in the original series:
 * The Anur System has an anti-matter sun.
 * All Loboan cubs have green eyes, whereas adults have red and pale orange eyes. Ben is exempt from this due to the Infinimatrix matching the aliens' eye colors with Ben's.
 * Devin existed.
 * Osmosians are aliens, not a human subspecies.
 * The sun Osmos and the planets revolving it exist.
 * Dr. Animo did not go insane before the time frame of Omniverse.
