Wonder Man #8 (1991 1st Series)

Having gained an audience with Empress Lilandra, the Shi'ar Avengers away team witnesses Lilandra christen the Nega-Portal for launch. The Starjammers, minus Binary, are sent to tow the "portal" to the Kree Empire, but Corsair protests against sending such a tool through his home space. Lilandra responds like Gladiator did in Thor 445: the concerns of one planet are subordinate to the needs of an entire galactic empire, especially one engaged in "total war." The remaining Starjammers accept the commission, leaving Corsair behind. Wonder Man, however, knows the Nega-Portal is actually a weapon, not just a tool. Grabbing Vision, he leaps aboard the Nega-Bomb and abandons the rest of the Avengers.
