Baby Face

Achilles Heel: Baby Face by Senator Cybus

The character stopped growing before he hit puberty; he is at most 4 feet +1D4 inches tall, and looks to be 5 +1D4 years old!
This in no way affects his powers: he can punch through bank vaults with the best of 'em. Equally, the character can be of any age, despite appearances. However, in any situation that requires adults to take him seriously, he is at a massive disadvantage: skills such as Interrogation, Seduction and the like suffer a penalty of -50%!
This assumes that anyone will even allow him to use his skills: no one wants to let a nine year old drive their car, fly a helicopter or perform emergency surgery on injured by-standers. This character had best have his I.D. on him at all times...
