[@The 42nd Gecko] It's been stated that Grafdakka has little issue with mobility when space is available and we've yet to see Miyu's mech in action, so I would say that he's slower than Grafdakka, but able to go head-to-head with a fair number of the Machina's creations and walk out in one piece. Injured, certainly, but that's what medics are for.
