One of the minor roles in the Suicide Squad movie is a character called Slipknot. Without spoiling it he has only a little screen time..... I know very little outside of the movie about this character. I though that he must be some sort of climbing expert/thief. However a look at the wiki has him as some sort of assassin who uses chemicals on his ropes to make them nearly indestructible.
In game terms he is extremely useful he is very fast, comes with a grapple gun armed with a knife and a bullet proof vest. Makes him ideal to grab loot. But where he truly shines for me in my Bane crew is one ability 'Arrest' allowing him to remove Knocked out Characters by spending a movement and special counter. Now this is something I struggle with in my Bane crew both Bane and his Bodyguard Venom Soldier are cracking fighters dealing lots of stun (which people can recover eventually) But the arrest ability allows me to get rid of them so that they come onto other targets.
So far I have managed to arrest Arsenal, Animated Black Canary and Strix. As well as moving a bomb to my opponents deployment zone in the final turn of a recent game. So pretty useful and all for only 42 rep and $100 funding.
