Talk about a shift in tone! After the darker edges of Ed Brubaker which started the Secret Avengers book, Warren Ellis has taken over with #16, and while he's no stranger to darkness, he does have a wonderfully strange sensibility.
Nextwave is a case in point. It took a strange amalgamation of heroes from all walks of the Marvel Universe and put them on a team to fight threats so ridiculously awesome that what was not supposed to be canon had to be blended in due to positive fan response. Now, Ellis seems to be bringing that crazy adventure style to Steve Rogers' covert ops squad – although how covert you can be when one of your team members is a viking woman riding a pegasus remains to be seen.
