Vision

Shifts from intangible to diamond-hard density as one continuous control, not two separate powers

Controls his density to pass through solid matter

Increases density instead, becoming nearly immovable

Phases a hand into a body and solidifies — the ability's lethal use, stated explicitly

Solar beam emitted from the forehead gem

Flies by reducing his own mass rather than by thrust

Interfaces with and overrides computer systems directly

Density control doubles as a barrier against energy attack
