so i heard that a guy on Reddit calms that he found leaked data about a doom patrol DLC level pack coming to the game in 2019 he said that he couldn't post it due to many legal reasons but he knows which charathers are going to be in this DLC pack the ones he listed were
robotman, negative man, Elasti-Girl, Crazy Jane, mento, elongated man, Flex Mentallo, Shrapnel and the Animal-Vegetable-Mineral Man
so one weird that he told me that elongated man was going to be on the DLC pack which made me wonder if he was even a member of the doom patrol so later on i search about it and it was true elongated man was a member of the doom patrol in the comics believe it or not.
I do think this might be true that were are getting a doom patrol DLC in the game because after all the doom patrol is getting there on TV show in 2019 so yeah this is most likely true that this DLC pack will come in 2019
