So I took an 100 theme challenge, or at least started it, and the first word was Blood. Blood being Blood Tech, the Shade powers that belong to Tech Mankato. When Tech sees his own blood he goes mentally insane, craving fights and seeing more blood. His regenerative abilities are to the point he can instantly regenerate just about anyone and his blood production is so fast if he does not rapidly use or loose his blood abilities he could potentially drown in blood when he goes back to normal.
