I can see him being as strong as a knightmare in that world (as his powers will be limited in that world). I guess the police have knightmares and tanks of there own, so he could take the apperance of one of thoses.

what I won't allow lowering is:
- dulling down of the riot cannon (it's capable of reducing his opponents to dust in a single shot)
- weakening of his physical strength
You can remove:
- Dark energon (Maybe he can't use it, however it literally is fused inside his spark, so it's always with him)
- Leach ability (Since I don't think many worlds have Energon deposits)
- possibly over shield. (although that's a part of his biology, so it's iffy)

What makes it hard to remove his strength is that the powers he has are not necessarily powers, but integral parts of his biology. Kinda like if a character had an arm removed.

Also, he's probably too vain to scan an earth vehicle.

Oh, and the standard Knightmare is 1/2 his height. (At around 15 feet, even Bumblebee is taller than them))
