So if your character is taking all the mass of the whole planet, then I assume that his powers can absorb the mass of things touching the things he's touching, so part of this depends on what still has mass once he's absorbed the mass of the planet.

As a human is much smaller than the Earth, the distance between Gary's surface and his center of mass will mean a much higher gravitational force.

Anything left with it's own mass (including atmosphere if it still has mass) will start falling towards Gary. Things with mass near Gary will be crushed and anything with mass on the other side of the planet will effectively be launched into orbit around Gary, as he's effectively just doubled their distance to the center of gravity they were falling towards previously.

I'm assuming that the things without mass can't be crushed in this state as the gold cube didn't implode previously, but anything not fixed down, while not affected by Gary's gravitational field, will now be free to drift off into space unless trapped by other forces heading towards Gary.
