These three assassins take on Batman, Nightwing, Damien Wayne, BAtgirl, Batwoman, Catwoman, Red Robin, Red Hood and Oracle.
They get standard gear and standard weapons. Yes, Deadpool gets the teleporting belt. Sabretooth has his adamantium skeleton. Taksmaster gets standard gear.
This is a random encounter. They clash on the rooftops of Gotham. They have little information about each other.
