It is uncommon for a squad of cybertronians that can assemble and combine their bodies to be at peace in life. These bot's combine into a single robot that is larger and more powerful than the average transformer. Thus it is understandable for their to be warring personalities and a constant wariness to bots that want to exploiate them.

Historically speaking, the art of combination originated when the first combiner, the 7th prime, came into existence alongside the enigma of combination. That prime was Nexus Prime, The father of the combiners.

combiners consist often of 4-7 bots who link together. Combiners can be tall, small, smart, or dumb. But this sub faction is quite diverse and spans millennia while other sub-factions may exist for a few centuries or more.

Defensor. Oh galant and empathetic defensor He was the perfect conjunx in cybertronian standards and a saint via human standards. His combination consisting of Hot Spot, First Aid, Streetwise, Blades, and Groove. The protectobots were a kind unit, and always made sure others were okay before themselves.

Defensor was ever a gentle giant. And you knew it.

"we missed you, sunshine" he smiled and it felt like everything bad just disappeared.
