Just because I fell the need to flesh out the mechs from after OG 1 a little bit.
Alteisen, literally translated from German as 'Old Iron', was given a major upgrade in the war against the Shadow Mirrors, Inspectors and the Einst after being nearly totally destroyed in a battle. Given increased armour, a five barreled autocannon, a MUCH larger Claymore capacity and having it's Revolver Stake replaced with the larger Revolving Bunker which had been intended for the original, it was renamed Alteisen Reise, or 'Old Iron Giant'. This new incarnation was equiped with a telsa drive system, but is unable to fly, as it is to heavy to even walk otherwise.
Weisritter, meaning 'White Knight', also recieved a major upgrade during this time. After being captured by the Einst a large percentage of the mech was converted to almost purely organic material. Renamed the Rein WeissRitter (lit 'Pure White Knight'), it was only usable by Excellen. After the events of the war, the original story was that it downgraded to the original Weis, while the new OGs game states that it kept the upgrade.

Giganscudo, lit Giant Shield, was also given a small upgrade (at least the one Tasuku pilots). It's shield arms were replaced by 'Stealth Anchors', the mech itself was given even MORE
Armour, and it's barrier was upgraded to a G-territory, over twice the power of the G-wall system. In honour of the upgrades it was given the new name Giganscudo Duro (short, Gan-Duro), meaning 'Hard Giant Shield' (seriously, who's idea was that?).
On the Grungust series, the type 0 went missing for a time, then was piloted by old master Rishu, who taught both Zengar (I won't call him his translated name, Okay) and Brooklyn Luckfield. It's current status is unknown.
The type one continued to serve as a trusty ride for Irm (though in OG2 it gets picked to death by Grunts piloting the original, now outdated, Lions).
The Type two was created, and several models were produced. All were equiped with a T-Link system for it's barrier system, though it isn't essential for any other part of the mech. Originally intended to surpass the Type one in every way, time and budget constraints led to the removal of the Gust-Lander (tank) mode, and decreased it's potential power. It still boasts a MUCH
longer range with it's chest cannon, an open palmed boost knuckle and a rather awesome looking calamity sword. Two of these mechs made their way into the possesion of ATX team members Brooklyn and Kusuha.
There was also a type three model produced. At least three such models were produced. The first, which had a blade based on the type zero's, was deployed from TLI during the inspector/einst war to an Major Zonbolt. Later it showed up during the battle to liberate TLI, when one of it's arms was completely destroyed and it's blade lost. The second unit boasted no special abilities except for two cocpits and a T-Link system. It was piloted by both Brooklyn Luckfield (primary pilot) and Kusuha Mizuha (secondary pilot), and dissapeared during the battle at Cheu hill, China. The third was outfitted with a Tronium power source and given a Shishino blade of appropriate size for a super type. Once again piloted by Brooklyn and Kusuha, this mech has not been destroyed. All models boast eye lasers, drill equiped boost knuckles, and a short range chest cannon.
As for the Space Noahs, the Shirogane was repaired during the six months following the DC and Aerogator war, and was later destroyed when the captain turned traitor. The Kurogane continued to evade the EFA's sights, but is now commanded by a man named Elzam who calls everything else he pilots Trombe. Other than that, there was mention of MP (mass produced) Noah's being built on the moon. Most likely they would be more on line with the Shirogane than the other two, with no major bow weapon to speak of.
Information, including height,weight and weaponry of a mech in the OG verse can be found here. Just ignore plot details if you don't want to know about something.
Current MP units include; Gespenst Mk II-M, Huckebein Mk II-M, Lion series mechs, and Shadow Mirror mechs (most likely mao still has the plans) which are Laz Aggrif, R-Eins, Ashsaber M, and Randgrith.
There are times for magic, there are time for martial arts, and there are times for giant Tiger-Dragon Robots that have both.
Beware the Otaku. He commands a mech that can unleash 123632 gigatons. Thats the equivalent of shooting Chicago, and knocking down ever building from Colorado to Maine.
