Sylph Young is one of the oldest and long-running characters in all of my fictional universes; she's ridiculously huge, impossibly strong (even taking her size into consideration), and, paradoxically, incredibly sweet. Because muscle growth comes so easily to her, she actually spends less time in the gym (okay, in her own, specially made gym, since no normal gym could accommodate her) than an average gym rat, preferring to spend her time painting or tailoring. She also has a full time job as both an architect and a construction worker, which she needs because, with her mass and strength, she inadvertently wrecks an awful lot of expensive things entirely by accident.
