Tact Mayers♂

Tact was defined by three things: his carefree attitude, his empathic nature and his sharp mind. While on the surface he appeared to be unreliable and lazy, he was actually a highly competent strategist and tactician. As his friend Lester remarks at one point, while Tact's behavior is embarrassing at times, he is at his best when it matters the most.
