Tenma #58732 - "Dog Walker"

We will never know what caused Tenma to break his genetic conditioning. Some Tenmas were drivers, and others delivery men. Perhaps "Express" was too embarrassed to admit that he was a former dog walker, and pretends to be a delivery man instead.

In homage to his shame, Tenma emulates his old profession in a war against the corporations he loathes, all the time trying to hide his dark secret.
