While fighting on Sherman Dam, Optimus Prime and Megatron reveal their unique weapons: Optimus retracts his right hand and replaces it with a glowing energon axe, and Megatron turns his right hand into energon flail. Though this is the only episode these weapons are in use, they were very memorable abilities, since the original toys came with them as well. Later releases Optimus and Megatron's toys included them as accessories.
When the nearly human-sized Ravage transforms and shrinks into his cassette-mode, you can see flashes of light surrounding the rocket launchers on his hips as they disappear. Fans have speculated that this effect was supposed to show them being "teleported" into a pocket-dimension while he is in his alternate mode. Unfortunately, in later episodes the uses of these effects gradually diminished and pieces of equipment such as the rocket launchers in question simply "popped" out of nothing when the characters transformed.
