Medusa

Medusa is an alien in the Transformers in 3D portion of the Generation 1 continuity family.

Is she Golobulus' long-lost sister?

Medusa is the female member of the Destructons. Armed with huge forearm-mounted spikes, the tail of her snake-like body, and devastating "Medusa Beams," she is every bit as much the force of destruction as her comrades.
