LONGARM just wants to help, whether it's hauling a stuck are out of a ditch or providing covering fire for a flanking action. As long as he's providing assistance to others you'll see a big grin on his face, that is, after all, what being an AUTOBOT is all about - helping, saving, protecting. He just doesn't get the DECEPTICONS. They all seem so selfish. It doesn't make sence to him why anyone would want to live like that. It would be so tiring to be so mean all the time.
