Technical Overview
Sounderous is a flying battleship with green, black, white, and yellow color scheme in its standard Fortress Mode (フォートレスモード, Fōtoresu Mōdo) which serves as means of transportation for Gridknight Alliance as well as providing firepower against kaiju threats. It is also designed to travel between universes.
In its Battle Mode (バトルモード, Batoru Mōdo), it appears as powered armor themed after original Anosillus and its wearer's possible true form. As The 2nd dons Sounderous' Battle Mode in conjunction of a specialized suit after enlarging herself, it effectively serves the role of Assist Weapon just like Dynazenon.
