Heavy laser-class BETA Magnus Luxcius: Unioculus "Magnus Lux" With the capability to track targets from 38 kilometres away, 12 seconds in-between each shot and a perfect record of never hitting allied BETA strains in a crossfire, the Laser-class played an instrumental role in shutting down mankind's air superiority on the field of battle, and continues to be a deadly anti-air force to this day.

Their giant eyes fire lasers that are effective against targets of up to 10 kilometres high and 30 kilometres from the where the Laser-class stands. Laser-class BETA Luxcius: Duo oculus "Lux"Īt 3 metres tall, the Laser-class BETA are some of the smaller anti-TSF units the BETA field, and are lightly armored to the extent where they can be easily taken down with 36mm cannons. Ultimately, these are only what have been identified and/or spotted on Earth, and there are probably many more strains not present. Several more exist, possible in support functions of varying importance.

Mankind has identified several strains of BETA, of which seven have been identified to serve on the field. They have been likened to the space monsters of Top wo Nerae! (and to a lesser extent, the Buff Clan of Ideon)- Their biggest strength is in their numbers and capability for a battle of attrition, and they are notable for being incredibly ugly in apperance. From what the Superior says, it sounds like this refers to the number of BETA, but Takeru takes it to refer to the number of Superiors if it is indeed the latter, and each Superior has a number of BETA under it equal to that of Earth's, that would mean there are probably around 10^37+10^37x7^10 to 10^37+10^37x9^10 BETA in existence. Also, there are apparently at least 10^37 BETA scattered throughout the universe. They consider humans to be resources to be recycled. They do not consider humans to be life-forms because we are carbon-based- They do not consider themselves to be life-forms, as they are actually biological weapons created by a being known only as the "Creator", a silicon-based life-form, and so only consider silicon-based entities to be life-forms (the superior states that it is impossible for carbon-based life-forms to occur naturally). We find out more about the BETA from Takeru's conversation with the Superior at the end of Alternative. All that mankind knows of them during Unlimited and at the start of Alternative is that they are (obviously) hostile, are carbon-based lifeforms (this was discovered when specimens were examined in Alternative 2), and don't consider humans to be living beings (this was found out through Soviet psychics' readings in Alternative 3). Their very existence is shrouded in mystery. They cannot fly, and so shoot down anything that does, rendering aircraft useless and making evacuation a lot more difficult. They vary greatly in size, the smallest identified strains (soldier-class) being around three metres tall, and the largest identified strains (fort-class) at over sixty metres tall.

When they first arrived in Japan in 1998, 36 million people were dead within a week. By 2001, the world population is down to 1 billion people. Muv-Luv Unlimited and Alternative take place in alternate worlds where the BETA invaded Earth in 1973 after arriving on the Moon in 1967 and being spotted on Mars in 1958. They features most heavily in Muv-Luv Unlimited and Muv-Luv Alternative, where they are the primary antagonistic faction against humanity's forces. The' ' Beings of the Extra Terrestrial origin which is Adversary of human race, more commonly known by the acronym "BETA" are a fictional extraterrestrial lifeform in the Muv-Luv computer games.
