New Avengers #5 2010

New Avengers #5 (2005) continues the 'Breakout!' storyline with the team stranded in the Savage Land. Iron Man battles a Tyrannosaurus Rex from the inside, while Wolverine tracks Karl Lykos. Lykos transforms into Sauron after absorbing Wolverine's mutant energy, then hypnotizes the Avengers before being shot by SHIELD agents led by Yelena Belova. This issue is notable for Sauron's apparent death and the significant involvement of Yelena Belova, as well as Wolverine's integration into the New Avengers roster.
