Teen Titans, Vol. 3 #10 (2004)

Raven Rising, Part 1
Birds all over San Francisco are disturbed. A horrific skeletal Trigon rises from a bay of blood. Beast Boy keeps repeating "Raven belongs to Brother Blood". All of this is Raven reaching out of help. The birds lead the Titans to a large cave, and in that cave they discover the reformed Church of Blood. Unknown to them, Deathstroke and Ravager have also discovered this lair. Inside it, they find a huge ceremony and a new Brother Blood - a child of fourteen! But this Brother Blood may be more dangerous than his predecessors, for he takes an active role in the battle. And he takes a bite out of Superboy, drinking his blood and gaining his powers! With these, he opens a crack in the Earth, and the Titans fall in...
