Another round of action poses from "Transformers: Prime" Robots In Disguise Decepticon Rumble after the previous posting. ^^
The "hidden" combined cannon mode for the pile drivers was introduced in Part 2, but wasn't shown in the previous posting. ^^
Supported using Soul Stage Act 5 Action Support Type for Mechanics Clear Ver.
The peg slot to attach the weapons in vehicle mode can be accessed in robot mode as well. ^^
Using the ports shown above, the pile drivers can become Rumble's waist mounted cannons, ...
... or extra boosters in robot mode. ^^
These two functions for the pile drivers are exactly how the ports were used in vehicle mode. ^^
Even more action poses from Rumble coming up in the next posting, which is going to be the last one for this review series. ^^
