Earth Federation Mobile Suit
RX-78GP04G Gundam Gerbera

This is how Gundam 0083's Gerbera Tetra would have looked, had it been completed as part of the Earth Federation's Gundam Development Project. Like the Gerbera Tetra, it's armed with a large beam rifle and can be outfitted with stürm booster units for increased range. The design was originally created by mechanical designer Mika Akitaka for Hobby Japan's Gundam Weapons 3.
