Thaddeus Thawne is a clone of Bart Allen, and was created in the 30th century by Bart's maternal grandfather, President Thawne. Thawne, being the descendant of the Flash's enemy Professor Zoom, got tired of his grandson's crime fighting activities in the 20th century and decided to create a clone of Bart using more Thawne blood so that he would be more ruthless. In addition to this modification, Thaddeus's growth and development was slowed. This is in contrast to Bart's accelerated development, (becoming physically 15 at chronological age 2). This was done to give Thad more training and knowledge than Bart ever would. His mission as the "Reverse-Impulse" was to go back in time and replace Bart
