Dr Quease is a world renouned scientist on mutation theories in Ninja Turtles: The Next Mutation. No one else in the scientific community will take Quease seriously, except for Donatello who thinks Quease is a genius. He has been recruited to work for the Dragon Lord in hopes that he can figure out what made the Turtles so big. Once he finds out, Quease will feed the 'evidence' to the Dragon Lord in hopes that the king of dragons can also gain the mutant powers. Quease is incredibly arrogant and rude, and does not take lightly to those who point out flaws in his theories.
