WAIT JUST A MINUTEEE
"Miles and Miles G are literally Sonic and Shadow!" SHUT UP. THEY ARE TAILS AND NINE.
In Nine's universe, the Eggmen took over the world. Just like the sinister six took over Earth 42.
At least in my mind, the phrase "he's just like Tails, he's just a little.. angsty!" fits Miles G perfectly
"Tails" and "Nine" are just nicknames. Their real name is "MILES PROWER"
