It seems that Warbot-002 is not a repaint of Springer/Defender.

It was pointed out that FP add a letter to the end of their product names for repaints. e.g. Shadow Scyther is TFX-04B. So a Defender repaint would be named WB-001B.

Venksta also pretty much confirmed that WB-002 is either Broadside or Wreck-Gar.
