I was thinking & since Sam is old enough to get married,I thought of this plot for TF4. Sam is married to Carly & has a son named Spike (As a refrence to G1). The Autobots have gotten rid of just about every decepticon on earth & on Cybertron.The humans have started To travel to Cybertron & have set up buildings for people who hate to live near idiots.Sam is one of those people.Even though the Autobots saved earth twice,the president wants them to stay hidden so the new generation doesn't get to used to having robot friends since they rebuilt cybertron.The decepticons that have escaped the autobots have dedicated themselves to reviving a better leader then Megatron who failed 3 times.They unearth Megatron's teacher,Onslaught & his 7 combiner team allies. The Autobots discover this & (with Carly, Sam & Spike) Hunt them down with a new second in command named Silverbolt. Silverbolt was the first Combiner long ago,but lost them when Onslaught & his combaticons destroyed them. Any good?
