Thanks for the invitation! I'm in the Marvel universe, specifically Doomsday.

Su Yi has been in the Marvel world for three years. She thought she was just cannon fodder and that it would be good enough if she could just survive!
Who knew that in his most desperate moment, he would awaken the power of the Supreme Destruction Sun!
During those three years, he left behind countless terrifying legends.
When he got bored, a cross-dimensional chat group invited him to join.
Without any hesitation, Su Yi pressed the "Agree" button.
Whitebeard: "Gurararara, welcome to the dimensional chat group! I am the Emperor of the Sea, Whitebeard!"
Asuna Yuuki: "Welcome newbie! I'm Asuna, the poorest member of the group~"
CC: "Welcome, little brother! I'm forever eighteen!"
……
Looking at the familiar name before him, Su Yi said, "Thanks for the invitation! I'm in Marvel, specifically Doomsday!"
