There is a Deus Ex: Mankind Divided announcer pack that could potentially be added to Dota 2. I say "could" because the community still needs to vote it in on the Steam Community, but I'd say it's a pretty safe bet that it will be added.

Yes, the announce pack if of none other than Adam Jensen, voiced by Elias Toufexis and was officially created by Eidos Montreal.


And if that doesn't tickle your fancy, maybe the Rick and Morty pack is more to your liking?
