MG is the greatest speed fighter of all time. He's the most well rounded speed fighter ever. He's fast, technical, and most importantly, adaptable. His only real competition during his career was Kael and Hiro and he beat them both 20-0. The criteria being used to rank fighters are resume's, longevity, and accomplishments. So let's take a look at MG's resume.

5-4 victory vs. Kyros : At the time, Kyros was the pound for pound king and nobody could touch him. MG ended his reign and started his own with this win. This is significant because he surpassed the #1 fighter and he never redeemed this loss. Although a 5-4 loss might not seem that bad, it was the way that MG won. Kyros was winning 3-2 and MG landed 3 hits straight to seal the victory. Flik is the only other person to do this (when he beat Dragon Master Alex). This win also shows how MG beat not only the greats of his era but the greats of the era that preceded his. Lastly, this win shows his abiity to adapt. At the time, Kyros was faster than MG and MG had to outsmart him to win.

20-0 vs. Kael & 20-0 vs. Hiro: I don't think people understand the magnitude of these two victories. It's hard enough to beat someone 5-0 but 20-0? It's possible that's never been done in the first place, not to mention the caliber of the two fighters it was done to, the #2 and #3 ranked fighters of the time. Both fighters were on top of their games at the time too. This is what sets MG apart from everyone else -- Flik couldn't even 5-0 the #2 guy during his era, let alone 20-0. These two wins are MGs greatest accomplishments.

2-1 in Bo3 vs. Ukyo Hikuraga: This win cements MG's legacy as the best ever. At the time, he was out of practice. Ukyo had established himself as the #1 guy. He won the first fight, but in the second two MG adapted to his style and came out on top. This victory cemented his legacy because he'd beaten the #1 fighter before him, he crushed all competition during his reign at #1, and he beat the #1 fighter after him. No other fighter in history has done this. As for longevity, MG dominated for 6-7 years until he retired. Nobody retired him (like he did Kyros).  He went out on top. This is why MG is the greatest of all time.
