トリタテン
A "nen beast" created when [[Knuckle Bine]]'s [[Potclean]] transforms.
It looks like a purple cat with a pair or red [[wings]] and the hiragana と ("to") on its forehead.
Its ability is to latch onto its victim and force them into the "zetsu" state, preventing them from using [[nen_(hunter_x_hunter)|]].

Called I.R.S. (Individual Ren Suppressor) in the English translation.
