his fight with lee was nothing more that plot jutsu he couldn't keep up with lee without weights and would have been killed by primary lotus but magically he made a clone without a handseal and in a blink of an eye.... amazing huh. Then lee went gates and played ping pong with him 5x the speed. So enlighten me on how gaara can beat lee let alone gai without a plot (by the way lee lost by dq)
gaara makes sand clones without handseals all the time you moron,he controls sand without handseals dosen't he?,and he outsmarted and outlasted lee in their fight. He has very good reaction to attacks as seen when he blocked point blank explosions the moment they explode. And 5 gated lee cudnt break his sand armour,he got up unfazed after that didnt he?. He can officially kill lee in seconds now so don't worry abt that.
He crushes guy low difficulty in the dessert,mid diff on a neutral terrain,gai's 7th gate attack can't breach through his air sand protective wall which easily blocked c3,his sand armour is wayy ahead of kisame's skin which tanked daytime trigger and still continued to fight. Morning peacock is obviously weaker than daytime trigger,and it's just a furry of punches,they arent breaching gaara's sand armour at all.
Guy and lee said it themselves that taijutsu alone is meaningless to gaara,he can't beat gaara,definately not in a dessert.
