Some of this sounds like BS to me.

the deal with Sam having an older brother seems kinda weird and outta nowhere.

Spike



buster

Spike is older then buster.

Marvel Comics continuity
Generation 1

Spike Witwicky was away at college for the first few years of the Autobot/Decepticon war on Earth until he returned home to find his younger brother Buster kidnapped by the Decepticons. Spike soon became the binary-bond partner to the Headmaster Fortress Maximus, after Fortress Maximus' first partner, Galen, was killed in a battle with the Deception Scorponok.

Thereafter he struggled with balancing his responsibillities to his family with those to the Autobots. Once Buster was rescued, and with Optimus Prime returned to life to take his place as Autobot leader, Spike went into retirement, mothballing poor Max. This retirement wouldn't last however as it was interupted, first by a pair of Decepticon Pretenders, then by the crash of the Ark and a raving Galvatron. Through the course of these conflicts Spike learned that the binary bonding he had undergone with Maximus was far deeper and more permanent than he'd believed. Fortress Maximus was always there with him in his head, always a part of him. After his battle with Galvatron he seemed to have made peace with his connection to Fortress Maximus and his role as (perhaps) the last Autobot protector of Earth.

Spike and Buster were both derived from the same "young male human friend" character in early backstory material.
