He was my first Motu figure (might even have been my very first action figure). I loved him because of his reptilian traits and even thought of him as some kind of sauropod - the long neck... What a great action feature it was. I used to have battles on top of the Ghostbusters firehouse and he knocked all other combatants (Turtles figures for example) down.
The 200X cartoon brought him back with a much bigger position - Commander of the Snakemen army and second in command to Hiss! Now he wasn't a mere lackey anymore. The new Rattlor is cunning, intelligent, agile AND powerful! Loved every bit of it!
Now when I started collecting MOTUC I couldn't wait for the 4HM to do their magic on him. And boy, MOTUC Rattlor is amazing! Such a detailed sculpt, plus neck extension. He even rattles (a bit).
Of course I had to give him his 200X armor. Now if Mattel would give us a 200X Rattlor head to go with it... I'd buy another to display both versions - I usually don't.
Rattlor's followed by Modulok, Leech and DB Skeletor (with different Skeletor body...).
