What did Happosai look like when he was young?

Most likely somewhere in between his own version of himself (extremely
handsome) and Cologne's version of him (short, ugly, just younger).  I'd
put him as a plain looking guy, not exceptional in any way except his MA
training...

In think so also... I bet he looked like a blond Ataru (from UY).
