Darkseid vs The Defenders

The deplorable lack of villains specific to the Defenders forced me to come up with this scenario.

Dr. Strange has something Darkseid wants. He'll stop at nothing to get it. The reason Darkseid knows about this is Korvac gave him the info. He forges an alliance with Korvac to take what he wants.
Darkseid gathers his troops and moves in. Due to an appalling lack of clixed Lieutenants, Darkseid must improvise.

Darkseid brings in those who are available to him:
Granny Goodness
Kalibak
Desaad
Lashina
Assorted Parademons
He also retrieves Knockout and forces her back into service.
Next he gathers up Doomsday, having solved the problem of how to control him long ago.
Then he recruits Deathstroke the Terminator, having found him effective.
Last, he commissions Lobo, offering him a bounty for each Defender he brings to him.
Korvac provides some Badoon warriors having subjugated them in revenge for his past as a slave of the Badoon empire.

Metron, in his thirst for knowledge discovers the plot of Korvac and Darkseid and after gathering Orion, Mister Miracle and Big Barda, warns Dr. Strange. Strange calls in the Defenders:
Namor
The Hulk
The Silver Surfer
Valkyrie
Nighthawk
Clea
Gargoyle
Hellcat
Angel
Beast
Iceman
Black Knight
Powerman
Moon Dragon
Howard The Duck (if you're feeling froggy)

If points aren't enough for the Defenders you may add Daredevil and/or the original members of the Guardians of the Galaxy
