The Doctor Is In-Doc Octopus that Is

 Otto Octavius was once an ordinary nuclear physicist until an accident created "Doctor Octopus!"

While the accident gave him great power it also twisted his mind into the evil power-hungry Doc Ock.

His mortal enemy is the Superhero Spiderman, who Doc Ock would gladly destroy-if he could.

Doctor Octopus is a plastic piece from Crisis Protocol that I painted this week.
