A new marshadow, well, kinda... Dex (short for Index) doesn't like being out in the open, but hiding in a robotic body he built works for him! And meeting Praj and Locke inspired him to make a whole line of Mechashadow suits to pilot.
Type 1 is old fashioned and rudimentary, mostly due to Dex's limits when he was first tasked with the job, you could even think of it as a prototype.
Mk II has the design sensibilities of a retro-futuristic machine still lacking engineering expertise, atleast he looks nice and shiny!
Version 3.0 leaps to that sleek and sterile design that modern technology leans on, but damn, his digital face display is adorable~
