These are one of my favourite gundam action sequences.Will add more of them here as soon as i get hold of them.
The first one is from GundamX TV series.The weapon used is called satellite cannon or something and it is awesome.It vapourises everything.Phew
The second one is from Gundam Seed Destiny . This one has one amazing fighting sequence . Total mayhem.
The next one is from victory Gundam.You can see the famous wings of light here.The Gundam propulsion doubles up as a weapon.
