You mean the time she assisted great hero Spike in his glorious rescue of Canterlot?
 
I guess you could count that as a partial.

@PonyPon  
Oh yeah, and: >>232319
 
Wouldn’t be the first time crustaceans got the better of her.

@ALIS  
What about the Cockatrices from the first arc?

Things that have defeated Princess Celestia so far.
 

It’s one thing for Celestia to be easily captured by those Lobsters.
 
But then again, Discord suffered himself when a Tatzlwurm sneezed on him. Just goes to show that almighty and powerful entities aren’t all that powerful to begin with. XP

@Trickquestion  
Meanwhile, at Canterlot:  

 
(I know these stories aren’t meant to be synchronous, but I can imagine Luna going crazy like this with Cele gone for a long period.)

Any excuse to stay away from court for a wee bit longer, eh Celestia?
 
She probably just spend a few days charming them up, get released on good terms, then come back Caesar style and crucify them all.

@Background Pony #013B  
Pretty sure that the next page of this is going to be her telling Spike to patient as she’s working on something. Which is probably a diplomatic solution.
 
Since these lobsters seem belligerent, she may just sigh and take them out in a few hits despairing that it had to come to this.

@Fortune  
not to mention she is at large a pacifist. they capreud them, but have not tried to actually hurt them yet. though that changes the moment it does.  
not to mentio nshe would have three broiled lobsters and they would go to waste in a land with a rather small population of sapient carnivores.

@Xonxt  
it was not the power of love it was a creatuer who ate just enough of the energy to overpower her.
 
believe it or not i can imagine her not resorting to violence outright. she owuld probably resort to it if they are a truer threat. not to mention her weakest attacks can puncture castle walls………..

@Background Pony #4BA6  
Is it that difficult to have Celestia kicking ass and breaking backs and skulls? I am sick and tired of this “Celestia does nothing and is useless” bullshit.

@Background Pony #A9EF  
Look at her face. She’s not worried.  
The longer she spends as a captive, the more info she gets and thus gives her better chances when she makes her move. Common ploy.

Tia how the heck did you let yourself getting captured by these guys? Or is this the case of flying is weak against rock?
 
Maybe she’s just waiting out the whole thing and gets into action when the time is right.

@Background Pony #4BA6  
The same way she gets her ass kicked by the power of love…

Aaaaand how exactly does an all-powerful demigod get captured by the likes of them?

@PonyPon  
Oh god, please let them called be that. I didn’t even make that connection!

I thought you only princess for ponies?
 
And oh god, Rock Lobsters!
