The Chemist was a walking encyclopedia on acids, explosives and poisons.
After the Jade Cat Statue was stolen from the Gotham University Museum with an acid, Catwoman and Batgirl looked up the Chemist at the Stacked Deck. They rounded him up, chased everyone else away and showed him residue of the chemicals. He knew it; it was made in Gotham, probably by Axis, Phoenix or Daggett Industries. Though he didn't say the last one out loud, Catwoman guessed it. In the confusion, the Chemist made a run for it.
- Dan Riba, director of "Batgirl Returns", modeled The Chemist after the notorious DC Comics villain Doctor Sivana, a classic foe of Captain Marvel.
