Who 或者 what is the most powerful 邪恶力量 creature San and Dean have encountered so far?

its gotta be the trickster, he's a demi god! prolly better than 天使 cuz he could just trick em idk thats a tough one sayin there better than 天使 but might actually be. so trickster!

Lilith 或者 Y.E.D 或者 even Meg but I'd say Liltih

I have to go with the archangel Zachariah. Castiel called them 'God's most fearsome warriors', and they'd have to pack some kind of celestial 冲床 to be called that! Since they've already established that Sam and Dean's destinies must be allowed to play out, we likely won't see just what he is capable of for a while. He will not interfere...yet.

(btw, this probably should have been a pick because it's an "opinion" question, ;) )

lillth,y.e.d 或者 the 天使 because the 天使 can send dean staight back to hell

deffo lilith

Sam and Dean thier most powerful creature they have run into is Angels. The only thing that can kill an 天使 is another 天使 probably GOD too but I'm not sure.

i would have to say the yellow eyed demom

i would say the yellow eyed demon. he killed the boys mother, and then sams girlfriend. he is the reason they started to hunt, just like their dad.

My vote is for Jamie(a boy born from a demonic bloodline). Although it is clear that Death(The Horseman i mean) is the strongest.

It has to be God!Castiel, even though we've only seen one scene of him yet. Apart from that I would say the Archangels 或者 Death.

This guy right here:

Leviathan, they are freaking powerful!!

Bloomin Castiel - Just can't get rid o the beggar!!!!! ;-)

Of course the real answer is the wonderful Death - he out lives everything! Oh Hail the Mighty Death (bowing lowly) !!!

Lilith, Yellow Eyed Demon, Dick...

Lucifer.

he's the freakin' devil!

I'm not going to give 你 just one but two most powerful beings and they are God and Death.

They met Zues who is a god and immortal, they also met Lilith created 由 god and is also immortal but both were killed a bit far fetched on the shows part lol.
