Answer:
Unstoppable
Step-by-step explanation:
Secure: Safe, protected, and free from danger or threat.
Supreme: Highest in rank, authority, or power; utmost or ultimate.
Unstoppable: Impossible to stop or prevent, continuously advancing or progressing.
Vulnerable: Susceptible to harm, injury, or attack, lacking protection or defense.
Invincible means incapable of being defeated, unbeatable, or impossible to overcome. It denotes a sense of ultimate strength and resilience, suggesting that nothing can stand in its way or bring it down.
Therefore, "Unstoppable" best captures the meaning of "Invincible."
