A powerful Exoshell that is able to "transform" into a fighter mode. All this does is give the Siren the ability to travel faster, to be equipped with a hyper drive and gain the ability to use its two Hi-Mega Particle Cannons. The Siren is a custom build ExoShell by Archer who's design and performance completely out matches Exoshells of the past, much like the ExoSX-000 "Alex", it would change the design ethics of the next generation of ExoShells. Because its his own design the ExoShell best fits his needs, wants and combat style. Which allows him to be even more effective in combat.
