So far the Autobots have been able to obtain all cybertronian artifacts. From the imobolizaer, to the energon extractor, the magnetic pulser thing, and now the spark extinguisher. So far Knock out will seem to escape with a new artifact though. I wonder if these artifacts will eventualy play a larger role. I'm also surprized that ratchet hasn't tried to weaponize them and upgraded them to fit the autobots. I think the imobolizer would be a great weapon to compact into an arm cannon similar to the EMP weapon Racthet had in TFA. These are some pretty powerful weapons and i'm surprised the autobots haven't taken more advantage of them to better deal with the decepticon threat and even the menace that was unicron. what are your thoughts?
