Anakin is combatively infinitely superior to the DMs, but his mind is so unstable it'd be honestly a piece of cake for the DMs to take advantage of it.
Mid-fight Anakin is losing to Dooku, you think he can handle a single Dread Master, let alone 6? These are the guys who solo fleets and resurrect the dead.
Even going by the novels degenerate version of events, all it took was a simple taunt to push Anakin into feeb territory. The DM's would incinerate his brain.
He definitey wasn't losing then, or when Dooku was able to force pwn Kenobi out of the fight at will, or when Dooku pushed Anakin and Obi-Wan's sabers back simultaneously with such force that Anakin nearly fell over and Dooku was able to kick him to the curb without even looking at him while taking Obi-Wan out of the fight with TK or when Dooku is clearly winning the saber lock.
Yep, his victory was never in doubt. Even in the novel when Dooku Dun Moch'd him and gained the upper hand.
Anakin isn't a skilled enough force user to defend against 6 highly powerful force users attacking him at once via lightning, drain, telepathy, tk and sorcery. Dooku alone is a tough opponent for him, in terms of the Force.
For some reason I thought you meant he couldn't defeat any of them, individually. With that, I agree. I meant Anakin is infinitely superior to each of them.
Perhaps, but the Masters can apparently channel the power of all the others even when it's just one of them. Anakin is still outmatched and against a vastly more advanced force user even taking one of them on imo. It took a strike team to defeat even a single Dread Master.
