What does prower mean?

Answer 1

The name Prower comes with Miles. Miles Prower.

Miles Prower actually means "Miles per hour" because with the help of his tails, Miles can run very fast, almost as fast as Sonic (Fast enough to catch up)

But Miles had been given a nickname "Tails" for his well known twin tails.

The reason why his tails are so memorable-

He can use it to fly, it works like a helicopter except the tails cannot twist.

If you look carefully, Tails' tails are actually rotating (Watch in Japanese Sonic anime Episode 10 or click on direct link below)you'll see it very clearly. It just happens that it is easier to edit Tails' tails to rotate in games, so ignore it.

His tails are probably the strongest among his features. It can break metal.

He uses his tails to attack (Watch in Japanese sonic anime Episode 45 or click on direct link below) and defend himself.

His tails are super fluffy <3

It just looks very cute when he raps it around himself :3
