Also known as: GT-FOUR, RX-78E
A transformable Mecha from the Gundam mechaverse. It first appeared in Gundam MS Generation.
The RX-78E Gundam GT-FOUR is an experimental prototype variable geometry Mobile Suit developed from the original RX-78-2 Gundam by the Earth Federation during the final days of The One Year War.
While the project was abandoned and the mecha was never mass produced, knowledge obtained from it greatly served for the successful development of future more advanced variable MS like the Asshimar and the Gaplant several years later.
