At Evo 2016, Two characters were announced for Tekken 7. We were shown Bob, and new character Master Raven. To quote the trailer
The original Raven made his debut in TEKKEN 5 with origins that are still murky today. Now Master Raven enters the fight in TEKKEN 7, executing her ninjutsu fighting skills with exceptional power and precision. Master Raven has no problem tearing her opponents apart in The King of Iron Fist Tournament.
This sounds like a cool character and you can check out her trailer below.
