Eriana-3/ ulan-tan Osiris Toland And just to make sure I succeed [spoiler]Randal the vandal. Sorry chief. But if it comes to it, guardians can't die unless you drain them of light (which Spartans cannot do), wait until the ghost runs out of light itself, which could take centuries, or destroy the ghost; which the Spartans wouldn't know about in the first place. Put that on top of the fact that we technically can't die when killed, can live through unfathomable torment and torture, and have capabilities that allow us to bend reality, disegrate enemies with arc energy, or sear off their skin (through their armor) and it's a clear win. Don't get me wrong I love chief. Bit he has one life, we have billions Also eriana-3 or ulan-tan can make quick work of any residual spartan, whilst osiris can lead his cult into war, and toland in his new "taken king form" can send a gargantuan nova bomb that could wipe out all of unsc and chief at the front[/spoiler]
