Here's a theoretical suggestion... how about the Tempered? With Special Charge stacked, and with the co-operation of your team, you can get a Wail in three flicks (given that your teammates don't cover much ground at the start).
Backing this up: on linear stages (mostly Triggerfish, Mackerel and, if you're very precise, Arowana), the Tri Nouveau (and other Seeker users) have a delightful manoeuvre whereby, perhaps with some Sub Saver and Ink Recovery, they can whale on the shield as a match starts by sending two Seekers simultaneously at it - one for your transport and one the moment you arrive. Then it can use its own attacks to try to finish the deal.
Thoroughly unrelated: does your username come from Hydreigon's Japanese name?
