Not a joke :D
There are the Karmans and they try to probe that they are also a force to take into account in the AT-43 universe.
They just arrived last week from their home world and joined the UNA first and then the Red Block in a "King of the Hill" scenario.
First impression, they are hard, really hard, but not indestructible. In both fights, the faction which with the Karmans were allied lost.
However, the last report from the front states that the UNA just got beaten up by those blue hairy guys :D
We will keep you posted...
