- For the original Pterodactyl Ghost in The Scooby-Doo Show, see Johnny.
Jonathan Jacobo is a former scientist who dressed up like the Pterodactyl Ghost to pull off bank robberies. After being defeated by Scooby-Doo and the gang, he was taken to jail, and his subsequent escape resulted in a near-death experience. Years later, he enacted an more complex plan involving the recreation of Scooby's previous monster enemies. Taking on the guise of both Heather Jasper Howe and the mysterious masked figure, his goal was to discredit Mystery Inc. and eventually destroy them (with the help of Ned). His plan was foiled when Scooby outwitted his monsters and used the control panel to destroy them. Jonathan and Ned were later taken back to jail.

Continuity issues
The original Pterodactyl Ghost in The Scooby-Doo Show was Johnny, who operated a delivery truck, and his criminal activity was about stolen CD's, not bank robbery. This is such a significant continuity difference that Jonathan Jacobo should probably be regarded as a different character than Johnny, either an AU version or a second criminal who used a Pterodactyl disguise.
