Now, this is a separate 'Death Battle' to my other series. This is just me giving the reasons as to why GAARA would win. Unlike screwattack, who again ignored the facts about Gaara's true feats, I will present the facts on Gaara and why he would win.

Strength:

Gaara lifted Madara's meteor. Now this meteor was MULTIPLE mountain size. But I'm going to lowball this feet and say that the meteor is the size of Mt. Everest. Now, how much does Everest weigh? The answer is 159 billion tons. Now Gaara didn't lift this by himself, he had help from the Sugchikage, who reduced the weight by at least half, so if we divide 159 billion by 2 we get: 79 billion tons. This is FAR greater than any strength feat possessed by Toph Beifong.

Speed:

Gaara takes this gategory for one main reason, Toph's seismic sense would not be able to keep up with Gaara's sand. Why? Well let's take a look.

Seismic movement is about 8km/s. This is approx. how fast Toph's seismic sense is, now Toph's combat speed is that of a normal person. So the question is, is Gaara's sand faster than 8km/s? The answer is yes, why? Because we see Gaara stop an attack from the Raikage who is faster than lightning. So even if Toph could sense the attacks coming... She is PHYSICALLY not fast enough to dodge the attacks.

Durability:

Gaara and his sand surviving a blast similar to a nuclear explosion from Deidara's C3 bombs. That's all I have to say here. Gaara wins in Durability, also lets not forget the punishment he took from Rock Lee where he was basically made into a human pinball and still won the fight...

Stamina:

Gaara fought for days with no sleep or rest against Madara in the 4th Great Shinobi war and guess what? No signs of fatigue or tiredness of any kind. Toph has not shown anything comparable to this in the comics or cartoon.

Now the big question is, can Toph bend Gaara's gold dust and sand? The answer is surprisingly, no! The reason for this is because the sand contains Chakra and Gaara's mothers will. So if Toph attempted to bend it, it would actually fight against her since this sand is directly linked to Gaara.

The winner of this fight should be Gaara.
