1) Laserbeak, Buzzsaw, Sundor (from Sun and Condor) and the retool Ratbat
2) Rumble, Frenzy and the retools Eject and Rewind
3) Ravage and possibly Steeljaw
While spelling it Sundor for the reason you stated above makes sense- that's what the original toy was called/spelled- I thought I'd seen in all the official announcements and listings that his toy was spelled Sunder. I could be wrong, though.
