The clip The Evil Masked Figure's identity from Scooby Doo 2: Monsters Unleashed (2004) with Peter Boyle, Tim Blake Nelson
Do you know the identity of the Evil Masked Figure behind it all?
If our hunch is correct, the Evil Masked Figure is...
But she was at the museum when the Masked Figure was on the roof.
You almost had me there, didn't you?
Lucky for her, she had an assistant helping her with her evil plans.
When I realized she was the Evil Masked Figure...
...he quickly changed into her costume.
But why did she do it?
Because Heather Jasper-Howe is actually...
...Doctor Jonathan Jacobo.
The original Pterodactyl Ghost.
But how do you know this?
A photo, taken of Jacobo in front of the Coolsonian.
Jacobo supposedly died a year before construction even began.
So Jacobo survived that fall off the prison wall.
He adapted the false Heather Jasper-Howe persona to turn the press against us.
Then he framed Old Man Wickles...
...by putting that book and The Black Knight Ghost in his mansion.
As if you getting the lead in My Fair Lady wasn't enough!
I was an excellent Eliza! You were too act-y.
And stealing my Tater Tots!
You kept saying you felt puffy!
