The Best Offense...

     .....Is a good Defense. And the best defense is Defensor, clearly.

     Another in that category titled toys I never had as a kid, Defensor was a combiner formed out of the Protectobots. They were five(now six) emergency and police vehicles, as follows

• Hot Spot (fire truck)
• Streetwise (police car)
• Blades (rescue helicopter)
• Groove (police motorcycle)
• First Aid (ambulance)
• Rook (S.W.A.T. vehicle)

     Here is what the TF Wiki says about Defensor:

The combined form of the five Protectobots Defensor exists specifically to safeguard human life. In many ways he feels about the human race the way a parent would their children and he would give his life away in an instant rather than let one human come to harm. Defensor is emotionally attached to humans on a level that sometimes worries his fellow Autobots. He identifies with them the same way a sheep dog would with its flock or a puppy with its human owners. As far as Defensor is concerned the humans are his "kind." Sadly the titanic robot giant's attempts at personal interaction and friendly exchanges with humans tend to fail. We humans tend to be more wary and frightened of his alien nature and great size than Defensor can understand. Despite this, Defensor is fairly well adjusted mentally compared to almost every other contemporary gestalt

Hot Spot

Streetwise, Shafted on TFWiki

Blades

Groove

First Aid

Rook, So named due to his tendency to stand in corners and move only in straight lines
(I think it's short for "Rookie")
that makes more sense...

And All together now...
