For Ultraman....ironic, yes, but also quite tragic in my opinion, since if you think about him logically he would win the whole thing, even against Godzilla since he's taken down several monsters of Godzilla's caliber in his time.

And as for the "serious secret weapon," Optimus actually has one: The Matrix of Leadership, which uses the Wisdom of the Ages to give Optimus the power of every dead Autobot (the number of which is larger than you might think).
