	120/80/80 is fragile?A very slow and kind of fragile cannon of power.

120/80/80 is fragile?![]()
EDIT : Heck I didn't see that it's very similar to Shoopz_Whisper 's Throh (yet I've read your post ;) ), I'll change it to make it more original if you want me to.
Nah, you good. Plus, yours isn't similar. Go look at Atk and Weight again. Pretty sure they're different.
