Alteisen

* Original model
* Riese model

Alteisen, later known as Alteisen Riese, is a real-life robot from the OG dimension piloted by Kyousuke.

## Origin

Previously, it had an alternative name - Gespent MK-III.

Designed by Dr. Marion Rad, the PTX-003C Alteisen uses a redesigned PTX-003 Gespent Type-T as its base and was not fitted with any additional technology as Marion was opposed to it. PT - Marion's application for a next generation personal soldier for mass production of the Earth Federation Army, such as the Gespenst Mk-III along with the Weissritter, replacing the production Gespenst Mk-II and developed in accordance with the ATX plan, the goal of which was to create high performance personal soldiers. However, the concept of the vehicle was considered erroneous: due to the heavy weight of the armor and weapons, no pilot could effectively use it. In addition, the Alteisen was designed primarily for close combat and lacked long-range weapons. Combined with the high cost of production, the Alteisen was considered too impractical for mass production. The only device created was given to ATX team member Keska Nanbu when Marion realized that he was the only person capable of unlocking the robot's full potential.

Aside from the initial settings, the OG Alteisen Riese shoulder fenders are said to be Tesla Drive balancers modified from Weissritter Tesla Drive parts, however they are designed to keep the PT on his feet without breaking due to the heavy weight and imbalance caused by the new hardware. This resulted in the Riese having limited low-altitude hovering capabilities compared to other Tesla-powered mechanical machines.

## Abilities

Each version is very different, but has almost the same set of weapons.

### **Split Missile**

On the Alteisen Riese's back are multiple missile containers which are launched at the enemy, followed by the missiles themselves deploying from the container.

### **Quintuple Chain Gun**

A five-barreled machine gun mounted on the Alteisen Riese's left arm, enhanced from Alteisen's Triple Machine Cannon. The barrel width had been decreased, however the ammunition count, effective firing range and rapid-firing capabilities had all been improved.

### **Plasma Horn**

Upgraded from the Heat Horn, the longer Plasma Horn now packs more slashing power when charged with electricity. It can now also be used to get rid of small obstacles instead of just being an emergency weapon.

### **Revolving Bunker**

The prototype of Alteisen's Revolving Stake, the mechanics behind the Revolving Bunker are exactly the same as with the Stake, except that the cylinder is much larger, yielding greater damage per charge. The weapon was initially shelved away due to severely unbalancing the Alteisen when equipped, however now with the Riese upgrade, the Bunker can finally see the light of day. It is equipped with a break-action revolving cylinder chamber and is reloaded using a speedloader stored on the Riese's back when out of ammo.

### **Avalanche Claymore**

The upgraded version of the Heavy Claymore, the Avalanche Claymore packs a significantly greater number of titanium pellets.

### **Boost Hammer**

A giant ball-and-chain flail for mid-to-close range combat. The ball section is equipped with thrusters for increased damaging power.
