Radius Lad is mute, but he is also a living antenna that can tap into a signal anywhere in the galaxy. He projects these signals as his voice , which he can weaponize depending on the signal. He also is an armored roly-poly that is nearly indestructible when rolled up.
Equipment
In the 31st Century as a member of the Legion of Super-Heroes, Radius Lad possesses a Legion Flight Ring. The ring gives its wearer the ability to fly, the speed and range of which is determined by the wearer’s willpower. It also acts as a long-range communicator (enabling constant vocal contact with other Legionnaires, even across vast distances of space), a signal device, and a navigational compass, all powered by a micro-computer built inside the ring.
