Ben 10 Season 3 Episode 11

Alien Mistransformations:

Four Arms-Stinkfly.
Heat Blast-Benmummy.
Four Arms-Cannon Bolt.

This episode aired as the season finale for Australia.

Despite Vilgax being the "main" villain of this series, Ghostfreak, with just one episode, was given enough status for the first two-part Ben 10 episode.

Main Villain Bio: Dr. Vicktor - An alien resembling Frankenstein's monster, Dr. Vicktor works at NASA, disguised as a human scientist as a means to hijack a space shuttle. He is incredibly intelligent, and working for Ghostfreak. His immediate plan was to resurrect his master, whose ultimate plan was to prevent the sun's light from reaching the earth using various satellites (therefore meaning that Ghostfreak would be at full power all of the time). He serves as the unofficial leader of the three horror-themed aliens. The purple lightning that the previous two horror aliens appeared in was generated by a teleportation machine that he uses.

The building where Ghostfreak was destroyed in "Ghostfreaked Out" is seen in this episode, as its presence is necessary to gather the ashes that would restore him to life.

XLR8's original transformation sequence is seen for the first time since "Kevin 11."

Aunt Vera (from "Permanent Retirement") is mentioned yet again in this episode.

Cartoon Network (UK) airdate: April 7th, 2007.

It is confirmed that the purple lightning is a form of teleportation, created by Vicktor to transport the mummy and wolf aliens.

Main Transformation(s): XLR8.

Gwen uses 2 new magic spells in this episode. The first spell was a water spell to catch the men in the water from escaping by making a fountain-type attack. The second spell was when she used the defense spell to protect herself, Ben, and Grandpa Max from the 3 aliens by summoning the giant energy snake to block the attack of Dr. Vicktor.

Running Gags:
1) The Omnitrix kept on preventing Ben from transforming into Four Arms by changing him into another alien.
2) Grandpa Max using a high-tech device and saying "Plumber's standard issue."
3) Gwen trying out a spell from Charmcaster's spellbook and it results in something unexpected.

Alien Form(s) Used:
1) Stinkfly.
2) Benmummy.
3) Cannon Bolt.
4) XLR8.

Ben uses his mummy alien form for the first time. Its name is Benmummy, according to the credits.

This is the first time that Gwen or Max has identified an alien as Ben based on the presence of the Omnitrix logo.

This is the first time an episode ends with a "To Be Continued," making it the first two-part episode.

It is revealed that Grandpa Max used to work for NASA. He also used to work along with Apollo 11's Neil Armstrong.

This episode marks the return of Ghostfreak since his last appearance in "Ghostfreaked Out."

We find out the Yenaldooshi werewolf alien survived the cave-in in "Benwolf" and it releases the mummy alien that got frozen by Ben in "Under Wraps."

Ghostfreak has three monster-themed alien minions: the werewolf alien, the mummy alien, and a Frankenstein's monster alien disguised as a scientist named Dr. Vicktor.
