In really weird circumstances, you can get level 2 to fatal. This was found out early in CS2. There's no practicality for it since in the instance where you can do it you can also do level 3. But it 's just there.
The glitch is you super jump 8D, throw a cannon, and then hit j.2CD before Rachel finishes recovering from the cannon. If you did it right, you'll get "FATAL" but you'll have the damage + bounce of a level 2 j.2C, not a level 3. If you did it too late, you'll get level 3.
