Gravattack doesn't become the black hole, he creates a black hole. If he became a black hole he would be dead anyway.

Alien X could just teleport of fly away. Bear in mind that we don't know EXACTLY how decisive the Gladiator was at that moment, or whether or not Alien X's black hole was a regular black hole.

Also Jetray cannot open portals. I have no idea where you got that from. But flying at faster-than-light speed (which he is shown to be able to do in the vacuum of space) may allow him to escape the pull of the black hole. may.
