Why is the Belial considered a 4th-generation Arm Slave?


Why is the _Plan-1055 Belial_ considered a 4th generation Arm Slave while the
_Plan-1056 Codarl_ and _Plan-1058 Codarl-i_ Arm Slaves, which were developed
from it, considered 3rd generation Arm Slaves?

According to [this entry](http://www.jindai-

> The suit is considered a fourth generation suit, making it more powerful

The Plan 1056 had an overheating problem that was fixed in the Arm Slave Plan
1058, when they installed an improved heat sink on it.

What makes the Plan 1055 a 4th Gen suit is that the Lambda Driver that it uses
and the capacity to fly, this means that the Lambda Driver and the features
added to this model are far beyond updated than the versions Plan 1056 and
Plan 1058.
