Banky Blaine

Banky Blaine, often going by simply Blaine, is the self-elected god of the dimension BTBBRBBQ. Born a human in an unknown dimension, he has become nearly unrecognisable as one, and seemingly immortal, due to the several technological augmentations of his being, supposedly gained while inside the pocket dimension. Incredibly megalomaniacal, extremely self-absorbed and just in general an all-round prick, he created and took control of a highly oppressive government in The BBQ.

Background
No-one knows where or when he came from, not even his home-dimension can be pinpointed, purely due to him telling the story a different way each time someone asks, and if anyone points out any discrepancies, they receive a bullet inside their head as compensation for their effort.

It is known that he was not the first inside The BBQ, but that's about as precise as it gets. Since his henchmen die around him from various diseases, old age or asking too many questions during storytime, he is the oldest living thing in pocket dimension, some rumors claim he might even be older than The Old Ones.
