Krato

Krato was a leader of the Originals, whose only appearance to date was calling a truce with Tanas- both men knew eachother to be members and indeed leaders of The Originals.

Quite Litterally the Only Post Krato Appears in:
"Tanas looked up at the building behind him, there was a beorc standing on the roof. " I got this!" Using rubble, he quickly went up the building, and found the man. "Tanas." "I'm afraid I have not met you before." Tanas replied, their conversation was too quiet for any to hear. "Please, I know you set it up." "What?" "You played them all like pawns...except me. But I suppose Caspio was a bit much for you." He pointed to the cut on Tanas' head. "..." Tanas droped the act. "Fine, Krato. You found me out. Too bad you can't do a thing about it." "I don't plan it....I admit I was a bit surprised to see you kill Caspio." "If your not here to do something, why are you here?" "I'll let you know that your done...I'm done. I dare not challenge you." "But what do you want. I know it was hard to find the identity of everyone...surely you want something from the effort." "Freedom. Touch me and you die. Swear upon it." "Fine...I'll hold no dagger to your throat if you leave your dagger sheathed." "Very well....Well, I suppose I should disappear, making you look mad would count I suppose." "Wha?" Tanas asked, as Krato disappeared. He shook his head, and went down. "What was that about?" Fetelo asked. "Its done." "Yea, but why'd you scramble up there? There was nothing there..." Elliot asked. "Nevermind...." Tanas replied."

-Krato's appearance in the War of Heroes

A Speculative View

 * It is clear that Krato's only appearance is in Tanas' head
 * Since Tanas was chosen by Logan (and Red did not choose a successor), Dale was chosen by Caspio, that leaves Tibald and Krato to have been chosen by either Helena or Adam. Since Adam was a noblemen, it makes more sense that he chose a Crimean Prince. That would mean Helena introduced Krato into the Oringals.
 * It is most likely Krato not Tibald who spoke with Caspio via a sending stone.
