Generic Roxas Clones is the unofficial name for the many people that claim they are Roxas and/or have Roxas-like traits such as summoning a keyblade.
Kizaru remains the only confirmed and known person to have killed a Roxas clone. Though there are probably others, they have not been recorded.
They still qualify as Generic Roxas Clones, just they stand out among the rest
The one that was killed by Kizaru and had the Chaos Keyblade (See here)
The one that killed a Sora clone because crap like this happens in rp.
The one that thinks he is friends with Kizaru and everyone else.
