"Titans Fit the Battle of Jericho" continues in Hawk and the Dove (1969) #5. First appearance of the Fat Man.
*A mysterious costumed crimefighter called Joshua invades Titan Lair and enlists the Teen Titans' aid in stopping a confrontation between police and teenage protesters. All involved are unaware that the protesters are being backed by organized crime figures, who in turn are pawns of the alien invaders from "Dimension X". The Titans, together with Joshua and his brother, the leader of the protesters, halt the aliens' scheme to release the Meroul Being, a monstrous giant creature, on Earth, but both the aliens and their criminal underlings continue to plot the team's downfall. *Source: Official Teen Titans Index #1 - Published by ICG
