First interaction with a HP's clone
Honestly I like so much the interaction with this clone, because of the trailer and previews I thought of the Clones only were cold and silent machines of war, that follow blindly the orders of Horde Prime, OK they do follow the orders of HP blindly but I got surprised when this clone began to speak in this way, I waited a robotic voice without expressiveness, but his tone was proud and arrogant. OK he sounds like a crazy fanatic xD ... Well now analyzing this, it made me remember when Hordak told Entrapta that he was a clone, a clone of the Emperor of the Known Universe: Horde Prime!
He looked so happy and proud talking about his master
Well maybe all the HP's clones understand his origen very well, therefore although Hordak hadn't been with Horde Prime for many years (maybe decades), he wanted to return with his master always.
Because Swift Wing said: Did Hordak talk this much?
Unlike Hordak, this clone (and the other clones) talk so much and look very "happy" (talking about his master).... maybe part of Hordak's mood changed living in Etheria, becoming cold and bitter, and until he met Entrapta, maybe, his only happy moment was the memory of his origen.
