Percolation Wave

The Percolation Energy Wave Event (Percolator or Percolation for short) is a barely-explicable space phenomenon in Dozerfleet Comics, resulting in crossover events similar in nature (though usually far less destructive) than what the Marvel Multiverse would dub an "incursion."

Percolation: MAA
Due to the instability in the greater Omniverse that had developed, the Marlquaan of Earth-G7.2.1 developed some hiccups that led to a self-aware offspring meta-energy source of similar nature to its parent. Becoming aware of other realities, the Percolator soon became a virus, setting out on a campaign of infecting itself into as many other universes as it could. In the fanfic crossover event Percolation (Gerosha Chronicles), the Extirpon of its native universe was thrust into a variant of Earth-12131, the Marvel world of Avengers Alliance on Facebook. Extirpon was sent along with Anarteq III (Isitoq Sundue) to work for SHIELD, while Danny Ketch and Jubilee got trapped in Earth-G7.2.1 and had to help Darius Philippine, SCALLOP, Navyrope, Seth Lambrelli, and the Gray Champion win an arms race against the Society of the Icy Finger for Marlquaanite rubies. Microwave Mouth (Janet Phillips) further complicated matters.

Eventually, Extirpon was sent home - but not before he was cloned. His clone stayed behind in Earth-12131 with a weakened version of his powers that channeled the Power Cosmic instead of the Marlquaan. That clone was named "Agent Opendi." The clone was initially crushed on by Sif, but later formed a relationship with Omega Sentinel.
