X-Men Pocket Book #15

In "Enter, the Avengers!", Professor X leads the X-Men to Bavaria, tracking down the villain Lucifer—whose deadly scheme threatens to destroy the world. There, they encounter the Avengers, who’ve arrived on the same mission, forcing a tense alliance as the X-Men must prevent the Avengers from defeating Lucifer, whose heartbeat is tied to a massive thermal bomb. With Xavier incapacitating Lucifer through a psychic blast, the team must now work together to disarm the bomb before it’s too late.

When the X-Men journey to the Savage Land on a mission to investigate the legendary Ka-Zar, they find themselves deep in the jungle, far from any known civilization. With Jean and Warren in danger at the hands of the savage Swamp Men, the team must rely on Ka-Zar and his loyal companion Zabu to survive the perilous wilderness.
