History

What happened before the Beowulves?

Excellen Browning was killed the shuttle crash during her cadet training. Her parents remade her into Lemon Browning.
Kyosuke Nanbu's Alt Eisen is called the Gespenst MK III, which is very similar to the former, only painted in blue. He also goes under the codename Beowulf (though his callsign remains "Assault-1" as in the OG universe), and unlike his Original Generation universe counterpart, Beowulf is said to possess a form of strength and skill that makes him demonic in nature. In Original Generations, it is heavily implied that his appearance and nature are a result of Einst influence.
The Elpis Incident killed the entire Branstein family, save its youngest son.
The Aerogaters never came to Earth; the Inspectors arrived, first.
Meteor-3 never crashed on Earth, but was sent by someone, thus effectively bringing the Tronium material to create the SRX.
Sanger Zonvolt was killed in combat, and Lemon Browning used his information to create Wodan Ymir, the 15th unit of the W-Numbers.
The Vanishing Trooper Incident provoked a heavy fear into Earth Federation mech designers by not creating any machine that resembles the Huckebein. In addition, the accident took the life of the remaining Branstein member, who survived the Elpis Incident.
