Kon-Shisho is a member of the Ninja Tribunal. He appeared in the 2003 animated series. He contains the power of the spirits and was the first to reveal his true form to the Turtles and their Acolyte friends.
He prominently appears during the fifth season of the 2003 series he also appeared in the Fast Forward episode The Journal and the season finale of Back to the Sewer with the rest of the Tribunal as a guest at the wedding of Casey Jones and April O'Neil.
Like most other members of the Tribunal, Kon's belief in the greater good along with his immortality has resulted in him seeing mortal beings as merely pawns in a greater game. Because of this Master Splinter considers him heartless and no better than the Shredder or his heralds. Kon also shows considerable arrogance, never considering that his judgement could be wrong and this arrogance also causes him to underestimate the Shredder's powerful heralds. However he does show shock upon discovering that Leonardo's spirit avatar is a Dragon saying it is "inconceivable for one so young."
