They battled against discord who is leagues above mumbo jumbo. Also rainbow dash, rarity,applejack and pinkie pie are country level twilight is solar system level, fluttershy is multi city block level and seeing how mumbo jumbo defeated base form raven who is star level by the way so twilight can one shot him and the element of harmony blast is a universe plus level attack the idw comics really buff up the mane 6, discord celestia and luna

Twilight’s Going Against One Of The Protagonists In Teen Titans Later This Month

well he’s master of your fate

@BronyHeresy  
so what? twilight, princess celestia and princess luna’s powers are pathetic compared to discord’s and from the looks of it mumbo jumbo has similar powers to that of discord.

mumbo jumbo wins. he’s basically discord if he was a magician but still has his godly powers.

6 on 1? really?

With just a wave of my magic wand,  
I’m master of your fate…

What kind of animals would the mane 6 end up as… One can wonder…

Considering that Death Battle intentionally overlooks the characters’ moral sensibilities, I think this would be a curb stomp by the Mane Six, and it has nothing to do with magic. Mumbo’s a reality warper? How nice for him. How is that going to affect a Pinkie Pie out for blood with no restraint?

Where is that picture of the Mane 6?

Yeah, but Raven has telekinesis, and she had just as much trouble fighting Mumbo as the rest of titans in “Bunny Raven.”
 
The Mane Six would win in the end, but he’d still give them a run for their money.

Mumbo is a reality warper like Discord, I wouldn’t put it past him to outright steal Twilight’s horn or otherwise silence her magic power.

Telekinesis + wand = broken wand. No contest. Also, countermagic, though that admittedly could cut either way.

@BronyHeresy
 
And I think you’re giving Twilight a bit too much credit. I’ve yet to see her create a pocket universe inside a hat.

@BronyHeresy
 
True, but she’s also still learning how to tap into and control her powers. Mumbo’s probably got a leg up on her in skill and execution. Still, I’d expect Twi to sooner get into a discussion with him much like Raven did.

Don’t forget that Mumbo’s pretty powerful in his own right. Watch his episode again.

Yes, sound, but powerwise, Twily’s the freakin’ God-Empress of Ponykind. Celestia herself said that Twilight was the most powerful unicorn she’d ever seen: HERSELF INCLUDED

^Wait I was thinking of Mad Mod. Still, Mumbo would just hot them right in their own home. The elements themselves are kept all the way in Canterlot.

@BronyHeresy
 
Remember how the Titans were just captured? They wouldn’t even have the elements on hand.

Pinkie would drive him nuts. In seconds.

They all end up in his hat.

Elements of Harmony versus this clown. What do you think?
