Mister Sinister: Mutant Supremacist Global

[dmrulesteam]

Mister Sinister: Dark Experimentation has a global that reads,

Global: Pay 3. Ignore target attacking character die's text until end of turn.

Suppose my opponent attacks with a character that has Deadly and I block it. I think use Mister Sinister's global to ignore the text on the Deadly character and after combat damage is dealt my blocker was not KO'd.
Since my blocker was at least temporarily engaged with a character with Deadly, will it still be KO'd at the end of the turn? Or will Mister Sinister's global prevent my character from being KO'd by Deadly?

Deadly: At the end of the turn, character dice that were engaged with a character die that has Deadly are KO’d (even if the character with Deadly has been KO’d or leaves the Field Zone). (MDM6)

Once a Character die engages with another Character die with Deadly, that Character die will be KO’d at the end of turn.
