Avengers West Coast Issue 61

Wanda Maximoff (Scarlet Witch) revealed to be a Nexus Being.

"The Immortus Imperative"

The character of Oort the Living Comet, an enemy of Quicksilver's from the future, is an original creation for this issue, as Quicksilver had no real rogues' gallery for the creative team to draw upon. So far, this has been Oort's only appearance.

NOTE: Nexus Beings are rare individual entities with the ability to affect probability and thus the future, thereby altering the flow of the Universal Time Stream. These beings, each referred to as a nexus, act as the keystones of the Multiverse and are crucial to its ultimate coherence and stability. Nexus Beings are vigilantly watched over by cosmic forces such as the Time Variance Authority and the Time-Keepers to be aware of any temporal changes that the nexi may cause to the Time Stream and act accordingly.
