A member of the League of Assassins who was transformed into a mutant elephant, tauntingly called Trunks by Batgirl. In the Batman Family and Ninja Turtles' siege on Ace Chemicals, he entered the fight by ramming the Turtle Van. Batgirl attacked him with her motorcycle, then lured him to a row of chemical tankers. Batgirl slid under the tankers as the mutant charged toward her, causing him to plow into them and detonate.
Powers and abilities
Assassination: As a human, he would have had to have been an exemplary assassin in order to have been a member of the League.
Mutant elephant physiology: After his mutation, this assassin's body gained the strength and durability of an elephant, as well as its natural defenses of tusks. However, either due to his bulky body or a likely decrease in strategic mind, he no longer performs his usual skills as an assassin in this form.
