1) Havoc because her power is soooo sinister Power: vaccum creation; Price: Drinking children's blood
2) Harvest: He's in the 3rd book. Power: Matter disintegration; Price: Swallowing round things
3) Jean: 1st season ep. 1 and 2. Power: Substitute matter, or the guy who could rip out someone's heart and place it somewhere else Price: Arranging things methodically and ruining it
4) Wei Zhijun: The blood guy. Power: Blood induced matter transportation; Price: Spilling his own blood
5) Hei of course! Power: Molecular manipulation; Price: None
