The Sons of Trigon can each wield the power of a Deadly Sin. Jared unleashes anger and wrath in his opponents and possesses super strength. Jesse sees into the head of his victim, and transforms himself into the thing they envy most[having their powers if that said thing is super-powered] . And Jacob invokes lust into the hearts of his prey. [caused flash and Donna troy to fight one another to the death over him]
thats all i could find. Sloth, Gluttony and Greed arnt mentioned.
from what iv seen in the recent 'titans' comic gluttony sucked dry both starfire and Donna until they were skeletal in appearance and weak. Sloth seemed to age nightwing and red arrow. he slowed them down and red arrow grew a beard. greed i think is still unknown but most likely like lust.
