Robin is the Batman's sidekick. There have been a few different Robins over the years including Dick Grayson and Jason Todd. But during the events of Arkham Knight, the Robin costume is worn by Tim Drake.
Tim was in the audience the night the Flying Graysons were murdered and it was there he saw Batman for the first time. Inspired by his heroic actions, Tim closely followed the exploits of Batman and Robin.
After some time, Tim managed to deduce the identities of Batman and Nightwing using his own self taught detective skills. Batman decided to put Tim through some very rigorous training where he eared the right to become the next Robin.
Robin has been through a lot during the Arkham Incidents but has always been there for Batman, as well as developing a very close relationship with Barbara Gordon. The once Batgirl, now Oracle.
Now, during the Scarecrows plans and Arkham Knight attacks, Robin has been using his detective skills to help Batman find out more about the patients that were transfused with the Joker's blood.
In the Batman Miniatures Game, Robin (Arkham Knight) is a Sidekick for the Batman crew.
Robin comes in at 78 Reputation. While he does take up a large portion of your crews reputation he does bring some very impressive skills to the table.
When closing in on the enemy, Robin has his Batlings handy and for close quarters he has his trusty Shielded Bo which he can use in a Combo. The Bo even comes in handy for covering him from incoming fire, adding an extra Ping roll for his safety.
Robin can be where needed very quickly with his Batclaw and Undercover deployment out of your set deployment zone. He also has a very handy Special Trait in Teamwork where he can call for help from nearby Allies that also have Teamwork and use two of their Action Counters as his own.
This is topped off with his Detective skills and his True Love for Barbara Gordon which will increase his effectiveness if she is taken out while on the same crew as Robin.
All in all, Robin (Arkham Knight) is a great choice as a Sidekick for a Batman crew. If it's along side Batman himself or with allies like Nightwing or Batgirl, Robin is a skilled fighter that can hold his own and support the rest of the Bat-Family.
Tim Drake has graduated the Robin program in Arkham Knight, becoming a Sidekick to aid Batman at re-taking Gotham. Armed with his Shielded Bo, Robin quickly closes the distance by being Undercover. Drake uses a new mechanic of Teamwork from the Arkham Knight video games to take down foes. Robin's mobility isn't hampered with his Batclaw and Batlings to help close the distance in his aid to clean up the streets of Gotham.
