Joseph Chadwick

Dr. Joseph Chadwick is the director of alien technology for the Forever Knights.

Ben 10: Alien Force
In his debut episode, Pet Project, Dr. Joseph was assigned to oversee the mass-production of a spacecraft that would have enabled the Forever Knights to travel to the alien dragon's planet after Ben Tennyson helped it escape in a previous episode. But because the device was too complex for human operation, Joseph sent Sir Morton to capture Ship to help perfect it. During the confrontation at his hideout, Dr. Chadwick used a control device on Ship that enabled him to control Ship's actions. That plan proved to be a complete failure later during the episode when Julie Yamamoto helped him (Ship) gain control of himself again. When Swampfire threw a fireball at a gas tank inside of the hideout, it exploded and caused a collapse in the hideout. While Sir Morton and his gang escaped, Joseph Chadwick was caught in the cave-in.

Trivia

 * His sinister and psychotic tendencies towards Ship and experimenting aliens for combat use are similar to the real-life Dr. Joseph Mengele (he and Chadwick even share the same first name), a WWII criminal also known as the "Angel of Death", while his status as weapons technician for a paramilitary group was inspired by Wernher von Braun, creator of the deadly V-2 combat rocket technology during WWII.
