Yes he was their leader beofre Optimus Prime was.
In transformers 3 an autobot dies. That autobot is ironhide. He gets shot right in the spark by a long lost autobot who turned bad named sentinal PRIME!
Sentinal Prime
the autobot that turns into a bad guy in transformers 3
His arm gets cut off by Sentinal in the battle if Chicago
Yes he gets killed by sentinal prime. Hoped this helped
Yes sentinal prime killed him because he made a deal with megatron
Sentinal prime comes to life because, optimus prime uses the matrix of leadership to bring him to life.
Depends on if you ae talking about a series, a specific episode or movie. My son says that in Transformers 3 there is 2 primes active : Optimus Prime and Sentinal Prime.
Optimus prime, Ironhide, Sideswipe, Mirage, Ratchet, Bumblebee, Wheeljack, Leadfoot, Topspin, Roadbuster, Brains, Wheelie, and Sentinal prime (but turns decipticon)
sentinel prime was the auto-bots first leader before optimus prime. sentinel was was slain by optimus prime because sentinel prime believed they could not win so he teamed up with the decepticons in transformers 3
sentinal prime kills ironhide using cosmic rust and a group of unnamed decepticons, soundwave, and baricade kill que/Wheeljack
the only autobot thats dies is ironhide. :(
