Is the Designer supposed to be...

... Moriarty?

... Moriarty?

Definitely gave off that kind of vibe, could also be Ra's Al Ghul especially with the whole resurrection plot.

Is resurrection confirmed?

I was wondering if the defeated/disgraced detective-foe could have assumed the Designer identity.

[nonsense man]

I can agree with the Dr Moriarty theory though joker did kill him and I think the joker stole the plans the others made and is using them or one of the original designers underlings well that is my theory on that

[the illustrious mr. kenway]

I saw him as a pastiche or homage to Moriarty than the man himself.

My headcanon is the detective he(?) mentions was the Crimson Avenger or Slam Bradley etc.

Given that they were fighting with swords, I thought the detective was Headmaster Hammer from Gotham Academy, and that the "death of the detective" Designer was talking about was metaphorical.
