Solar Beam (ソーラービーム, Sōrā Bīmu) is Overgrowth's signature technique which he later taught to his younger brother, Undergrowth.

Overgrowth draws in sunlight using the green patches on his body which glow yellow with energy. He then concentrates the energy into the palm of his hands, forming a yellow sphere of energy. Overgrowth finally pushes the sphere forward and fires a yellow energy wave at the opponent.
