Microsoft had an exclusivity deal on those back in the Xbox 360 days, so one could only assume - even though it's been nearly ten years - that they're included in the Xbox One version, though it's looking very unlikely considering Activision hasn't said a word. DLC characters are notably missing from PS4 and PC. In the case of Marvel Ultimate Alliance, the re-release isn't even the complete package. That is to say: very little effort has gone into making them. The PlayStation 4 ports (Xbox One come out later) are definitely on par with previous Activision-published re-releases like Prototype and Deadpool. To its credit, the studio said not to expect the pair to be enhanced or remastered, just touched up for modern consoles.
Marvel surprised many with the announcement at SDCC last weekend that both Marvel Ultimate Alliance games would be getting a digital re-release on PC, PS4, and Xbox One. A new bar for low-effort 'remasters' has definitely been set.
