Protoform Optimus Prime

In the 2007 live-action film Transformers, Autobots en route to Earth change their alternate modes into structures called space travel pods and enter the planet's atmosphere in the same way as a meteor. Thereafter, the Cybertronians change to a humanoid shaped endoskeleton structure known as Protoform.

Once they arrive, Cybertronians in protoform state will transform into an equally detailed yet generic & undefined robot mode to allow them more stable ground mobility in order to search for an adaptable disguised form (aka vehicle mode); upon which scanning and replication are initiated and completed within seconds, giving them their now-unique physical characteristics. These near-identical transformable skeleton-like forms are referred as protoforms. A protoform retains the same mass as the final appearance of a Cybertronian with a chosen vehicle mode after scanning & replication are complete, so one protoform can be larger and/or smaller than another.

Robots in Disguise - Fire Convoy

Transformers: Robots in Disguise is an anime series which has an associated toy line released in 2001 by Hasbro. The anime and toy line were originally released in Japan in 2000 by Takara as Transformers: Car Robots (トランスフォーマー・カーロボット^?).

The Robots in Disguise version of Optimus Prime transforms into a modern fire truck. The fire truck divides into two halves, of which the front half transforms into Optimus Prime's robot mode, and the rear half transforms into a battle station with facilities for field repairs. In robot mode Optimus Prime can combine with the trailer module to increase his size and strength. In this mode he is loaded with weapons, of which one is the giant water cannon within his ladder. The jet from the water cannon has an enormous force, so strong that it can send its targets into orbit.
