Logan Gratha

Logan Gratha is a Human male bounty hunter, also going by the name of Diabullet and a Metahuman.

He has a prior connection to both Mari McCabe and Oliver Queen.

Village of the Vixen
He was in the employment of a warlord of the Bannerless Legion. He joined the legion in slaughtering an entire village, getting rid of the elder people and taking the children with them. Coinicdently he was the one who killed the parents of Mari McCabe in that village.

Arrival of the Vixen
When Mari McCabe arrives on the second mark of her map, Logan Gratha ambushes her. Originally oblivious to the fact that he killed her parents, Diabullet attacks her, using his diamond hardened abilities to turn his skin into unbreakable diamond. Before able to deal the finishing blow against Mari, Barry Allen as the Flash intervenes, knocking him out. He is chased by both Flash and Mari, but manages to escape.

The following night when he returns to his hideout, one of the three safehouses he created in Central City, he finds Mari again and a friend from her past. He fights both of them, but both ultimately get away when the CCPD arrive on scene and contain and detain him.

Gratha was captured by the CCPD and put in a cell in their precinct. However Captain Cold had other plans, as he and Heat Wave freed him from captivity, only to demand that he would lead them to a hidden gold chest he had hidden in Gemcore City. He agreed to take them there.

Hunt the Gold
He along with Captain Cold and Heat Wave meet with Captain Bennett outside the GCCPD precinct where they learned where Lisa Snart was. He assisted Snart and Rory in freeing Snart's sister by using his ability to turn his arms into diamond and deflect the bullets. He informs them the gold chest is in the Gemcore Mining Center.

He, along with Snart, Rory and Lisa Snart entered the sewers below Gemcore City and headed towards the Gemcore Mining Center. There they briefly fought The Flash and Mari McCabe as they followed them. Logan and Captain Cold went on to the archives, but there it was revealed Logan had lied about the chest, it being a chest of Brotone instead of gold and enraged Captain Cold and Logan faced off along with Mari. When Firestorm intervened, an explosion came as a result of a crash, destroying much of the archives.

He managed to get away from Mari before she woke up and he was chased down eventually by Mari to Quattro Gemma Park. Finally Diabullet faces off against Mari and later Payton Bennett, but proved to be more then supreme against them. He regenerates most of his skin but when The Flash and Firestorm join in, Diabullet finally is beaten and caged up and brought to the plane on Central City Airfield. Payton and Mari reveal he is to stand trial to the Council of Elders.
