I have always loved killer croc but the version i grew up with was the 90's animated series of batman where he was a grey giant with lumpy skin so i tried going for that version while also trying to make him more realistic to go with Christopher Nolan’s universe.

After the events of Gotham city's siege, Bane still survives and has found refuge down in the sewers of Gotham City where he came across this man...a monster he stood 7 foot tall and was immensely powerful Perhaps stronger than Bane himself. He was a former inmate of 'Arkham Asylum' who once escaped through the sewer ducts where he has been living for the past 10 plus years, living of rats and other vermin plus the occasional dead body that washed through the sewers.
over years Bane had taught him, trained him and showed him the way of the 'League of Shadows'.
He has been given the code name 'THE CROC' for his remarkable skills and patience that it takes to ambushed his victims not just for his looks and his appetite for human flesh
He a terrifying soldier waiting for Banes command on the 'DAY OF THE KNIGHT' where they will ripp the bat limb from limb and eat the heart from each and everyone one of those Gotham Knight saviours
