Sentinel Prime went to reason with Megatron, seeking to reach him sermon and doctrine, he failed and tortured and destroyed by Megatron.
But, Megatron was chagrined to discover, Sentinel Prime (suspecting he may be killed) had not brough the Matrix with him into battle.
The Matrix used a vision of Sentinel Prime to strengthen Optimus Prime's resolve during a battle with Megatron by confronting him with the claim that Megatron had chosen Optimus to be Prime, knowing that he was weak.
Though the validity of the Matrix's claim was never directly resolved, in The War Within, Megatron Template:Tooltip that he 'rigged the game' in order to get the Matrix, possibly influencing the Ancients to choose Optimus from among a field of candidates.
The Keepers subsequently drew on Optimus's memories of Sentinel Prime to construct a robotic duplicate to confuse Prime and undermine his confidence. Though he posessed all of Sentinel Prime's considerable abilities which Optimus remembered, he eventually realised that this duplicate, created from his memories, was incapable of doing anything new. Optimus destroyed Sentinel Prime's duplicate, having largely overcome his own doubts about his fitness to be Autobot leader.
