Darkness Uprising

Darkness Uprising is a secret mission played in Dark Bloontonium Lab- a mimic of bloontonium lab with 32 small pieces of space around it. Each one needs a single Unstable Beacon (1 dark bloontonium unit infused with 500 bloontonium units.), and upon that, the message "Death is upon you, you are on the precipice, go forth, fight the Darkness once and for all... The E.N.T.I.T.Y. is upon you, proceed and fight, or turn back and live in shame... Your Choice...

A dialog box will then ask you if you want to continue.Hitting yes will destroy the stage, and the void below will disappear, taking you to the Dark Entity Chamber which houses the most powerful boss... E.N.T.I.T.Y. has gained the power of Dark Bloontonium and has teamed up with the Dark Plasma Boss, creating the Dark E.N.T.I.T.Y., an even more powerful boss. Also, there is no Omegachi to help you here. You will have to also contend with dark blasma bursts dealing mega-damage and 7 Dark Entity Auracrysts (500,000 HP each, boss has 3,500,000 HP,). Beating it needs Dark Plasma items, monkeys, and bombs to win.
