Execun

Execun is one of Exeller's servants. He is a clone of Exeller meant to represent his cunning.

Sonic.exe: The Whisper of Soul
Execun first appears in this game, on either Cream's first level (depending on if you catch Alice), or Cream's second level.

If you're unable to catch Alice in time, Cream looks for Cheese once more and finds out that the Chao is dead. Shortly after, Exeller disguised as Sonic arrives on the scene and tells her to go home while he looks for Cheese's murderer. Cream goes home to find her mother, Vanilla is acting weird. Turns out, Execun was the one to kill Cheese and has already killed Vanilla and disguised as her. He attempts to kill Cream, but he's stopped by the latter accidentally turning on a flashlight. Throughout the level, he tries to kill Cream while disguised as Vanilla.

If Cream catches up to Alice, Execun isn't seen until the ending cutscene of Exebark's level where he chases Cream despite Exebark being sent after her. Either way, Tails Doll saves her and they make a trek through the forest with Execun and Exebark hunting them.

Best Ending
If no one has died, Tails Doll remains functional decides to take Cream to Volcano Valley, but on the way there Execun ambushes them and knocks them out of the sky. They threaten Tails Doll to find the location of Cream when they land in a cave, and Cream comes out of the shadows herself. She uses the Chaos Emerald to knock away Execun from Tails Doll, who has to save Cream from getting attacked by Exebark.

Execun's next appearance happens during the attack on Freedom City. He along with Exebark and Exeller's other servants attack the various generators around Freedom City, causing Sally to have to defend them.
