[b]RX-78-5 Gundam Unit 5 "G05"[/b]
The fifth Gundam unit produced during the One Year War. Rebuilt for space combat and given a different finish with red accents, Unit 5 possessed a massive Giant Gatling gun that was extremely powerful - so powerful indeed it had a 5-second maximum firing time limit to avoid damaging the weapon.
