Oh gosh, ages old superhero.
Breadman.
In crap, rushed drawing form.
When a lorry taking radioactive waste to an out-of-the-way location exploded - it sent a shard of metal into the back of a super market home delivery van.
This in turn sent the contents, now poisoned with radiation flying - there we fortunatly no casualties - even the drivers of the vans got away safely.
There were, however, after affects of the accident. [name never decided] was hit in the head with a stray loaf. Although causing no serious damage, it did mold onto his head (there are still debates whether this is serious or not.) and he gained somewhat laughable super powers.
From this day forward he was known as breadman.
The power to fight evil, with all his bread like properties.
Growing in size while in heat.
A hard-as-toast shield.
And finds medicinal properties in flour and other bread ingredients.
However, he doesn't do well near water.
