Yeah, wiki kind'a blows ...however... there's another source I personally have bookmarked: The Atomic Think Tank Archive that has this pretty epic thread where a guy made these 'character builds'...it's about 3-4 years old, but is incredibly comprehensive and is almost 700 pages long.
Anyway, here's what he has to say about Annihilus:
"...with Annihilation, Annihilus became a big bad in his own right, and during the course of the event, the following died: Quasar (Wendell Vaughn), all of Xandar, the ENTIRE Nova Corps save Richard Rider, 90% of all the Skrull homeworlds, and billions of lives caught in the way. That's a tally that even Thanos wouldn't scoff at, and most of HIS deaths have been reversed!
-Annihilus is a high-powered bad-ass, capable of beating Ben Grimm or Blastaar in simple hand-to-hand, when he's using the Cosmic Control Rod to wipe the floor with entire groups of people. This is sorta him before the Annihilation Wave, when he's just a guy who can fly down to Earth and smack around Thor for a while, but maybe still lose. During Annihilation, he swiped Wendell Vaughn's Quantum Bands and amped his power to the point where a full-on Universe-Destroying Blast by GALACTUS just manages to leave him weakened enough that Nova Prime can use Extra Effort and kill him. Yeah, a planetary system and 9 million Negative Zone Bug Ships wiped off the map, and Annihilus was still kicking ass."
Hope that helps
