I don't think you can find them. Never seen stats on any event toons. It's announced as "very hard" and way above the difficulty of other legendary events except the very recent C3po event.
Also the npcs start with preloaded tm in this event. The main hurdle is for the essentials to survive until you even you get a turn.
