He has reappeared in-game after being freed by The Foundation in Chapter 2 Season 8.

It's unclear when or even if she'll be added to the game as a skin.3) Live event confirmediFireMonkey@iFireMonkeyEvent Gameplay Cues50454Event Gameplay Cues https://t.co/Xy4mY73iuxWhile there's no confirmation of The Paradigm being added as an NPC or skin, she's likely to appear during the upcoming live event. As predicted by theorists and leakers, the Doomsday Device will indeed be put to use by the Imagined Order.If the leaks turn out to be true, players will likely be piloting the Mecha to use it in battle against this evil device.

While the naming scheme may suggest Doom Slayer, that's unlikely to be the case.The Fortnite NPC is likely to be another original character added towards the end of the season. It's unclear who or what this character is and what their role will be as the season comes to a close.
