Captain Cabbage
In his secret identity he is innocuous, mild mannered and slightly mildewed night porter Yowwa, known within the organisation were he works as a clumsy and hard of hearing cretin.
His retiring personality and complete absence of friends mark him as a complete and utter waste of space - but, do not be fooled by his slight build, his dim witted outlook and slightly yellowed teeth, for when danger lurks and innocents are in peril he heads to his shabby office and with a shout of 'Evil is Afoot', he is changed with a mighty crash of thunder and a blinding flash of light into Captain Cabbage!
Except that he isn't!
Because he was thrown out of his office as he kept setting off the fire alarms whenever he transformed. Still, the coal shed is equally as secretive a place to change.
He was granted his amazing power one day when he was having his dinner of sausage and cabbage. What he didn't know was that his microwave had a fault which, as he was heating his meal the cabbage became irradiated with 'Z' Rays, a deadly mutated radiation which, once consumed, enabled his super powers.
Able to leap coffee tables with a single bound; fly through the air at almost three mph (for extremely short bursts), and with amazing strength (almost) he is more than a match for any three year old!
He laughs in the face of danger!
He scoffs mortal peril!
He IS CAPTAIN CABBAGE!
