Mecha- A synthetic or artificial creature or machine which is of generally humanoid or other form. An intelligent program of piece of code inhabiting or controlling a body is also known as a mecha, which is short for mechanical.
In the poorly produced A.I., which made a mockery of us AI programmers, the mecha known as David was abondoned by his mother, only to ressurect a copy of her in the distant future and watch her die after she falls asleep the first day of her new life.

MEChA stands for Movimiento Estudiantil Chican@ de Aztlan. Or Student Movement Chican@ of Aztlan. The official moto of MEChA is "La Union Hace La Fuerza" or 'Together we are stronger'.

The purpose of MEChA is encourage Chican@s to go finish college, a safe place for Chican@s to discuss political issues, and to organize protests and/or boycotts.

MEChA was founded in the 1960's during the protests of the war in Vietnam. During this time they published some documents that some took as militant. But since then MEChA has yet to organize any kind of violent protest.

Many have used MEChA documents from the 1960's to smear MEChA but have yet to point out any current events that would be considered violent or militant.

All MEChA chapters are independent from one another. Meaning that one MEChA chapter does not take orders from another chapter.
