I was wondering why some of the BW figs I got have working rubsigns (like G1 figs), and others don't... all are Takara originals, and were bought MISB... The ones that had them were Dirgegun (destron) and BigMos (cybertron), and the ones that didn't were Depth Charge ("Metals" version, if there were others), Tigatron, (both cybertrons,) and HardHead, a destron. Why were only some released with rubsigns, and did the Hasbro versions have rubsigns too?

hasbro had them, they werent in the first waves, but they evetually got them a little before the transmetals

Some of the first wave mold were later repainted with the rubsigns. Like Terrorsaur to Lazerbeak.

later beast wars toys like tm2 had spark crystals instead of rubsigns, dunno why though.

All of the Fuzors had them. I don't think any of the Transmetals or Transmetals 2 had them.

Transmetals had the rubsigns.

most of the tms had them and the fuzors

the predacon gestalt team also had the rub signs

original wave ones (megs and taranchulas did not)

I must not have any of the Transmetal that do have them... I can't think of any of mine that do.

I think TM2 Waspinator does.But I'm not sure.

TM2 Waspinator, dont you mean TM? TM Waspinator does has a rubsign.
