In my au RockTale, Bond Man is Gaster

After Wily's robots were banished underground along with Light's robots that rebelled, Bond Man was not only building homes and gluing them together (yes he glues stuff together), he was also the royal scientist for King. He had built a core-like area that is giving power to the underground. Then, something tragic happened. A mysterious robot was fighting off Bond Man while Bond Man was still studying what this "core" can do and he was violently shoved into his own creation, however one thing kept him alive, and it is unknown what it was. He is stuck in a void, hoping someone will find him.
