Details Regarding Omnipresence
While Omnipresence is, strictly speaking, not speed, it is listed as a speed statistic due to behaving in combat similarly to how normal speed would. For example, a being that is omnipresent within 3-D space would win every race against an opponent with normal speed, due to already being at the goal by the time the race starts. In addition, an attack from an omnipresent being is unavoidable with normal speed due to the attack being in every location in the universe at once.
It is commonly assumed that characters who are omnipresent across both space and time would be able to act and react much more quickly than regular characters, by virtue of their sheer size, but this is not always backed up by the source material. Though the nature of their existence makes fighting and harming them difficult for conventional fighters, requiring the use of abilities capable of affecting their entire being, as well as the ability to dodge their potentially omnipresent attacks, it is not necessarily impossible, as an omnipresent character's reaction time may still be limited.
This should all be analyzed on a case by case basis - omnipresent characters cannot be automatically assumed to have Infinite or Immeasurable speeds, and attacks coming from them do not necessarily cover the entire universe or multiverse. Some attacks can even be temporally but not spatially omnipresent, and these attacks do not necessarily move through space at Infinite or Immeasurable speeds. Despite the difficulty, it is possible for characters with certain abilities, such as Acausality, Cosmic Awareness, and Dimensional Travel, along with sufficient area of effect or hax, to keep up with omnipresent characters with measurable reaction and attack speeds.
Omnipresence must be specified in conjunction with the scale. Because omnipresence within a single 3+1-D universe (aka a regular 4-D space-time continuum) does not mean anything to regular life forms in higher dimensions of time and space (which might be larger and more complex than this universe).
A character that is omnipresent within a certain space is not necessarily swifter than all non-omnipresent beings. In addition, if a certain character is omnipresent on a universal scale, it is not a relevant advantage during a match-up against a character that can destroy universes.
