Being honest here: for a moment I thought they were riding on Fortress Maximus in his mobile fortress mode. I think I can be forgiven for mistaking the likeness.
That said, I think siccing the girls from GuP on Fort Max (and I do mean ALL OF THE GIRLS - he's got room for them) would be made of all kinds of win. As he is a pacifist, he might find Tankery to be an interesting means of settling who's best in a manner where no one gets hurt (well, beyond some bumps and bruises, but that's just the hazards that being a squishy organic comes with).
