Kenner R2-D2 action figure variations
The original R2-D2 was only produced mid-way through the Empire Strikes Back line. After that they produced the R2-D2 (with Sensor-scope) and later R2-D2 (with Pop-up Lightsaber) during the Power of the Force line.
Kenner produced an cartoon version of R2-D2 for the Droids line.
