Doraemon, realizing he was the main target, activated a Time-Lock Bubble, freezing time for 60 seconds.
"I have to go, Nobita," he said calmly. "They're trying to erase me — and if they do, everything I've done for you disappears."
"No!" Nobita cried, grabbing his best friend. "We'll fight them together!"
But Doraemon smiled. "You've grown stronger than you think. Maybe this is the moment you prove it."
He handed Nobita a final gadget — the Gadget Core — a sphere holding all remaining gadgets in case of emergencies.
Then, the Time-Lock ended.
In a flash of light, Doraemon vanished.
