Chuck's Reviews Transformers Cyberverse Ultra Class Rack N' Ruin
 

While I don't know much about Rack N' Ruin the character, the toy is really fun with an intuitive transformation that results in a solid vehicle mode. The Spark Armor "Gimmick" doesn't hinder the articulation of the figure and is quite fun. Rack N' Ruin is definitely worth an addition to your collection.
