it would be cool if they got leige Maximo as the main villain. and his first plans are to corrupt optimus's mind to betray the autobots and maybe kill BB or someone else to bring in a new character like hot shot or cliffjumper and after he is done messing with optimus's he reveals himself to the world and wrecks havoc on the world. then he realizes megatron was a failure and sees that he would rather bring shockwave back to life and make him more stronger. as optimus starts to feel normal again after leige Maximo corrupts his mind, he and the fellow autobots are ambushed and imprisoned. leige Maximo then steels optimus's matrix to then gain more knowledge on the autobot plans so that he has full control. he also uses the matrix to find where the key of vector sigma is.
