>>57011068yes it is, it's terrible in both BW1 and BW2. It has 0 move coverage, is terrible against Burgh, Elesa, Skyla, Brycen, and the dragon gym. It also gets destroyed by N.
It has terrible offenses, which makes its speed useless in a campaign run. It is only slightly bulky, if you can call it that. It has terrible HP. You're stuck using weak grass stab, slam and aerial ace.
I like Serperior, but gamefreak made it terrible just because contrary is good, which you can't even use in BW1.
