4th Time's a Charm

4th Time's a Charm is the fourth boss fight and the final story level of The 11th Dimension, as well as the twentieth main level of Crash Bandicoot 4: It's About Time.

Overview
Crash and Coco confront Doctor Neo Cortex who uses missiles, discs of light, and purple energy trombies, with the player using Kupuna-Wa to avoid them safely. Cortex also sends Punchbots and Kupuna-Wa needs to be used in order to spin them back towards Cortex.

After Cortex is defeated again, he laments the cycle of endless fighting between him and asks Crash if it would last forever, to which the bandicoot does not have an answer to. Doctor N. Tropy interrupts by mocking how Cortex couldn't handle this “simplest of tasks”. Cortex decides to quit, but discovers that N. Tropy doesn't need him anymore, because he found a new partner and a new plan. N. Tropy says that he has greater plans than conquering the multiverse and explains that he is going to use his generator to rewrite the history of the multiverse completely, ensuring that Cortex, the masks and especially the Bandicoots will never exist. Realizing they now have a common enemy, Cortex makes an alliance with Crash and Coco to defeat N. Tropy with Crash happily giving the doctor a hug.

Trivia

 * During this battle, Cortex says "Feel the wrath of Cortex!", a reference to the game Crash Bandicoot: The Wrath of Cortex.
