Does the character Sentinel Prime appear in any Transformers films?
Sentinel Prime
Sentinel Prime is the name of several fictional characters in the various "Transformers" series in the Transformers robot superhero franchise. First mention of Sentinel Prime was in issue #65 of the US Marvel Comics "Transformers" series, where he was mentioned to hold the Autobot Matrix of Leadership before Optimus Prime. Sentinel Prime is One of the members of the Dynasty of Primes and dedicated as the leader of the Autobots and has since appeared in a variety of forms as either Optimus Prime's mentor or friend. Fun Publications has also had a character in their comic called Sentinel Major, who is based on the "Transformers Animated" version of Sentinel Prime. He is also the main antagonist in the film "," where he betrays the Autobots and later Megatron for his own personal interests. His original "Generation 1" incarnation was later reimagined by IDW Publishing as a similar fallen figure, perhaps in lieu of his movie counterpart.
Smokescreen (Transformers)
Smokescreen first appears in "New Recruit", where he came from a downed Decepticon escape pod and arrived to help the Autobots fend off the Vehicons and an Insecticon. He then introduces himself to Optimus Prime and ended up recapping his history to the rest of Team Prime. Ratchet and Arcee had some trust issues with Smokescreen. When Optimus Prime asked about Alpha Trion, Smokescreen said that he didn't know what happened to him. Optimus then suggested to Smokescreen that he needed to become accustomed with his surroundings. Jack then gives him full run of the base, where Smokescreen discovered the Polarity gauntlet, the repaired Immobilizer, Phase Shifter, and the Spark Extractor, as well as Airachnid's stasis pod. Later, when Red Energon (which can make any Cybertronian faster) was first reported, Optimus Prime had Smokescreen obtain an Earth-based vehicle form and go through training. After picking the right vehicle, Smokescreen heard about Starscream attacking Optimus Prime and asks to be sent in, only to be denied. Smokescreen simply ignored him and joined the battle, using the Phase Shifter to get Starscream out of the Apex Armor. Optimus Prime tells Smokescreen standard procedure is required on the team.
