# Annihilators (Marvel Comics)

The Annihilators are a fictional team appearing in American comic books published by Marvel Comics. They are a group of powerful space-based characters from various alien races. They act as a deterrent to galactic war.

## Publication history

The team first assembled in The Thanos Imperative: Devastation one-shot (Jan 2011). They starred in a four-issue eponymous limited series, with a backup featuring Groot and Rocket Raccoon, which was previously announced as a separate limited series.
A second four-issue limited series, Annihilators: Earthfall, ran from September to December 2011.
In August 2014, the team appeared in the original graphic novel Thanos: The Infinity Revelation by Jim Starlin.

## Fictional team history

After a string of galactic-level threats (the Annihilation Wave, the Phalanx's conquest of the Kree, the War of Kings, and the Cancerverse invasion), Cosmo tries to fulfill the dream of his deceased friend and former Guardian of the Galaxy Star-Lord by assembling a proactive team to stop threats before the universe is in danger. He recruits the most powerful individuals he knows: the human Quasar, the Kree Ronan the Accuser, the Shi'ar Gladiator, the Korbinite Beta Ray Bill, and Herald of Galactus Silver Surfer. Each of them is initially resistant to the idea, but agree to join after they work together to defend Kree territory from Blastaar.
They are joined by the Galadorian Spaceknight Ikon, who needs their assistance protecting her planet from Doctor Dredd. After fending off Dire Wraiths and Immortus, they ultimately reveal Doctor Dredd to be a Skrull imposter.
Later, while trying to end a conflict between two factions of the Universal Church of Truth, the Annihilators learn of a plot to revive the Magus. They travel to Earth where the resurrection is happening but are unable to prevent it due to a conflict with the Avengers, who mistake the Annihilators for an invasion force. Quasar, Ikon, and Spider-Man discover the Magus has emerged from his cocoon in the form of a young boy. The Magus attempts to possess other humans on Earth, but Gladiator, Quasar, Ronan, and Iron Man are able to trick him back into his cocoon. The Annihilators take custody of the cocoon.

It has a double plinth, offset corner buttresses, dividing strings, battlemented parapet with pairs of corner pinnacles extended from buttresses, and central paired pinnacles corbelled off gargoyles.

# 48 Librae

48 Librae is a single shell star in the constellation Libra. It is a variable star with the designation FX Lib, ranging in magnitude from 4.74 to 4.96. Based upon an annual parallax shift of 6.97±0.24 mas as seen from Earth's orbit, it is located approximately 470 light years from the Sun. It is a candidate member of the Upper Scorpius group of the Scorpius–Centaurus association, with the former having an age of about 11 million years.
This is a main sequence Be star with a stellar classification of B3 Vsh, although it has been variously classed as B3V, B5IIIp shell He-n, B6p shell, B4III, B3IV:e-shell, and B3 shell by different sources. As is the norm for a shell star, it is spinning very rapidly with a projected rotational velocity of 400 km/s − matching or exceeding 80% of the critical velocity. This is giving the star a pronounced oblate shape with an equatorial bulge that is estimated to be 43% larger than the polar radius. It has six times the mass of the Sun and four times the Sun's radius. The star is radiating 1,100 times the Sun's luminosity from its photosphere at an effective temperature of 7,612 K.
The surrounding gaseous disk stretches out to at least 15 times the star's radius and is nearly aligned with the line of sight from the Earth, having an estimated inclination of 85°±3°. Some time between 1931 and 1935, the disk became active and has remained so since that time, becoming the subject of multiple studies. The unusual asymmetry in its emission lines have led to it being misclassified as a supergiant of type B8 Ia/Ib by SIMBAD and others. This asymmetry displays quasi-periodic behavior of the type found in about a third of all Be stars, with a period of about 10 to 17 years. This variation may arise from the precession of a one-armed density wave in the disk.
