User blog comment:Kitty 76/Shadow VS. Tails/@comment-2022427-20100426003703/@comment-101.160.130.66-20120604001551

Your wrong the real Tails stood toe-to-toe with Shadow and humiliated him, however Rouge broke the two of them up when Shadow started to get pissed. This happend in Sonic Battle

In Sonic X Tails can't even fight and he STILL mangaged to take every punch to the face Shadow gave him, although it looked like Shadow was about to kill him if the Materax did'nt show up.

So it is undecided, and don't forget without those rings around his wrists Shadow is the thrid weakess (notewrothy) character SOOOOOOOO HAhaha!
