In Angel's version, he was handcuffed, and put into the box with assistant standing on top of it. Illusionist Criss Angel assisted by Klayton and his other assistants has also performed the Metamorphosis trick as part of his 'Amystika' show. This evolution of the illusion was invented by Australian Illusionist John Taylor. Called the modern day metamorphosis, the trunk is suspended on a platform above the stage creating an aerial exchange. Pictured to the right is 'Suspended Animation'.

During the performance the assistant is trapped underwater with no source of air, and if something were to go wrong she would possibly drown. These variations add a significant element of peril.

Penn and Teller performed the illusion in an underwater theatre with a female assistant (a Weeki Wachee 'mermaid') handcuffed and locked in a steel cage on the sea bottom. In this version an acrylic tank filled with water is used and a beautiful swimsuit-clad woman assistant is locked inside underwater. Variations include the Aquarian Illusion created in the 1970s by Alan Wakeling for Mark Wilson, who performed it in The Magic Circus series and a HBO special Mumbo Jumbo! It's Magic, and in closing his Las Vegas shows. Modern version of Metamorphosis called Suspended Animation performed by grand illusionist Christian Farla
