If it survived the blast do you think it can be used to restore the Omega Lock and restore Cybertron.
Yes if it is in the hands of a true Prime, not in the hands of that handbook of morality catch phrases Optimus
It seems to work even in the hands of Optimus (Slag, why didn't OP just go to Cybertron and start hammering on the planet?)
The Prime hate is getting to be too much. Transformers: Prime is, before all else, an animated series geared towards children with some themes and content that adults can also enjoy. If you want hard decisions being made by leaders involving them sacrificing their own people, go watch "The Walking Dead" or "Battlestar Galactica" and stop whining. They're both on Netflix and Netflix Streaming. As for Prime, he did the right thing, defending the innocents who were caught in the crossfire of a war they didn't ask far. Even MurderDeathKillPrime of the Bay movies did the same thing in practically the same situation.
It was eluded to that the Forge of Solus could make the keys to the Omega Lock; however, Optimus stated that to do so would require skills that he did not possess. So would could assume that if the keys could be made with the Forge, so could the keys. If any of the WMD/Cybertronian artifacts survived season 2, I figure it would be the very weapons of the Primes: the Star Saber and the Forge. EDIT: The hammer cannot breath life into a dead world. The Forge cannot create life, which is the very thing Cybertron needs to be able to sustain for her People to return home.
