Cortex Vortex (ビリビリトラップ すりぬけろ lit. Slipping Through the Ripping Traps in Japanese) is the twenty-fifth level and is the last level of the fifth warp room in Crash Bandicoot: The Wrath of Cortex. It takes place in Cortex's space station and it's full of lab assistants, nitro crates and electrical traps set to kill Crash. This is one of only two platforming levels in this game without a Bonus Round, the other being Knight Time.
As with the last level in every warp room, it represents the boss that will be faced in factory form, in this case Cortex himself.
This is the only main platform level in the game to not have a bonus round.
In this level, the player has to go backwards to avoid electric fences, which is a reminiscence to Crash 2's Crash Dash (level), Crash Crush, and Un-Bearable. However, this time the player is not being chased.
