Do you think that there's ever gonna be something like this in Alan's channel, TDL teaming up with everyone else to fight a really dangerous and powerful threat?

Just like how Optimus and Megatron always team up to fight Unicron in literally every Transformers show ever.

Oh heck no. Dark is the "really dangerous and powerful threat." I'd imagine he enjoys that title.

Well, if SC outclasses him, he physically can't enjoy it anymore.

Chaos:

No... not when he's dead.

And now he's alive. So...truce?

He still ended SC's friends, so SC's gonna have to end him.

Hasn't SC done that already?

Yeah but "Somehow [The Dark Lord] returned."

At this point, I'd say that they're currently even. I just want to see a greater threat like Chaos in AvA or something...

We can't make an enemy too powerful. The best part is watching their defeat at the end of it, after all, and if it's too strong, then the hero would be overmatched more than Puss in Boots during his first run-in with the Wolf, or the 1000 rhino guards against Tai Lung.
