Now the concept is back. In grand fashion. Two teams from Marvel and two teams from Top Cow in the same book is a great way to start. Of course, Top Cow artists have been doing cover and interior work for the House of Ideas recently, so this is no big stretch. Fusion debuts spectacularly, with plenty of cool costumes and powers to please any fan of superheroes. This issue primarily focuses on the Mighty Avengers and Ripclaw, but with two more issues to come, the balance should be restored.
