4th Time's a Charm

4th Time's a Charm is the boss fight and the final story level of The 11th Dimension and 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 how the cycle of endless fighting between him and the Bandicoots seems to last forever. N. Tropy interrupts by saying how Cortex couldn't handle this samplest of tasks. Cortex decides to quit, while N. Tropy admits he doesn't need Cortex anymore, because he found a new partner and a new plan. N. Tropy says that the Rift Generator is too powerful for simply conquering the multiverse and decides to use his generator to rewrite the history of the multiverse completely, ensuring that even Cortex will never be born. Cortex makes an alliance with Crash and Coco to defeat N. Tropy.

Trivia

 * During this battle, Cortex mentions Nina and he says "the wrath of Cortex". The latter is a reference to another Crash Bandicoot game known as Crash Bandicoot 4 in Japan.
