So lets start with my number one character and, typical of the titles and period i'm on about, the best and most interesting ones are always the bad guys.
He's not interesting character-wise (apart from the bampot notion of aiding Germany in WW1 by using a squadron of giant killer bats. As you do) and really is just there to be thwarted whilst muttering "curses" and suchlike.
No, the reason he gets the vote is the barminess of the idea, along with the most stunning black and white artwork by (mainly) Alfonso Font. A master of the use of black, he created some brilliantly moody art on this strip, along with some excellent military rendidions - but mostly the stunningly eerie character designs for the bats and the Black Max himself, Maximillian Von Kloor.
Alfonso, i salute you.
