That's so interesting... [It's said with a bit of wonder, and a little hesitation as he seems to ponder.]

I wonder if the ancients, maybe even the Knights of Cybertron, had similar abilities.

They are ancient relics though, such feats are not common among us and certainly no individual has that capability.
