The Generation V timeline is proven to be in a completely separate universe from the Gens III and IV timeline(s) because of Volbeat and Illumise. In Gen III and IV, Volbeat eggs can only produce Volbeat when bred with Ditto. In Gen V and ever since, Volbeat and Ditto can produce either Volbeat or Illumise. A subtle retcon did away at the basic "standard timeline" theory. There are multiple timelines, and every Gen V timeline is in a separate plane of existence from every Gen III and IV timeline solely by this fact.
Volbeat and Illumise have design motifs around greasers and flappers, respectively, hinting at these Pokemon having been discovered relatively recently in the Pokemon universe.
Their leveling rates are completely different; Volbeat is in the Erratic group, and Illumise is in the Fluctuating group. Given their personality traits, it makes sense for Volbeat to be scattering about trying to court an Illumise
Volbeat are simp Pokemon. A single Illumise can swarm countless Volbeat, and all of them are trying to impress her. An Illumise has no loyalty to any one Volbeat, and she fluctuates from one Volbeat to the next.
Their Pokedex colors come from different places of their body. Volbeat's color is gray, referencing its gray skin. Illumise's should be blue on this logic, but it is instead purple to reference her hair and cuffs.
Volbeat and Illumise appear on separate days of the Bug-Catching Contest in Gen IV. Volbeat on Thursday. Illumise on Saturday. Saturday is the only day of the week that keeps its original Roman name. Illumise is the only one of the two to keep its original Japanese name.
Volbeat and Illumise have a strong association with the number 7, based on numerous factors.
