The first villian the JLA fought in their own series. Desparo wouldn't have a lot of appearances but they tended to matter when he did so up. In a mostly "holy crap we're all going to die!" kind of way.
When we first see him, Desparo is fairly skinny (later showings would have him bulked up considerably) but his main focus is on his mind.
The main character of the first story is a scientist, Jasonar, and his fleeing his world from Desparo. Jasonar needs time to finish a secret weapon capable of defeating the tyrant. Desparo knows about this and heads him off at the pass, easily taking the JLA out in the process.
How? Mostly by beating the Flash in a rigged chess game and teleporting each member or so to a different planet. They manage to get back to Earth, but it turns out JLA mascot Snapper Carr already took care of it. Yeah, remember that secret weapon? Carr found it and used it. Super easy, barely an inconvenience really.
So not the best introduction but things would get better, although nowadays he tends to be more Doomsday like than Dr. Doom.
