In Destroy All Monsters, the SoshingekiAngira's name comes from the film's Japanese title, specifically sōshingeki (総進撃?), meaning attack of the marching [monsters], and Angira, which comes from Anguirus's Japanese name, Angirasu (アンギラス?).
The differences that are seen in the SoshingekiAngira suit is that the neck is wider, and more muscular. The eyes are little larger, giving Anguirus a more heroic appearance, just like the Godzilla it appeared with. The teeth are shorter, now with fangs, and the carapace no longer flops up and down. The spikes on the carapace are now more scatter than in a straight line. This suit was also used for Anguirus' brief appearance in the opening of Godzilla vs. Megalon, and in Godzilla vs. MechaGodzilla, the fangs were removed. This suit is also known as the GiganAngira (ガイガンアンギラ?) in Godzilla vs. Gigan and MekaAngira (メカアンギラ?) in Godzilla vs. MechaGodzilla.
