Backtrack: Pull out the legs at the front and pull his feet out. Arms pull out the side and then slide upwards. If you can do this without using a tool or loosing an arm or forearm you have my admiration ! Back folds down to create the chest and swing round at the waist.
Spiral: Nearly the same except here the door panels form stabilizers down the back of the legs, and the arms fold down off the roof.
Oval: A Gobot with a jointed legs, and a small clever as the front folds down.
All 3 have joints at the hips, knees and shoulder, Spiral and Backtrack have ball joints there and waists too. There are elbows but they only bend about 10 degrees and the fore arms fall off at will ! But they all look OK as cars and seem quite stable as robots so..... All 3 have a powering socket somewhere underneath them in car mode.
They are the first set of Minicons I've got that don't do anything apart from be small robots !"
Oval - like the rest of the Street Speed Team - is a car. In his initial release he was orange with a grey underside. His headlights are oval shaped and he has a small spoiler at the rear behind some cooling vents.
If you turn the car over there's a Minicon socket at the back and to one side. This can be used to mount the car on a larger robot and (with some imagination) you can pretend it's body armour or a power pack.
TF: Pull back on the back of the car to form the legs. Fold the front of the car over onto the robot's body. Swing the sides down as arms, fold the roof down as the robot's back, Fold the head up.
Robot maintains the orange from the car exposing some grey on the body and upper legs, and having a silver visor on the face. He's got ball jointed hips, arms that move at the shoulders and bend in the middle. The mid arm joint is weak like the rest of the SST. Generally he holds together better than the other though, but the point where car front locks to robot body is weak.
OK but small car (especially for a Minicon). Flimsy robot.
Oval was available with the rest of the Street Speed Team as the Micron team numbered MM-06 where he was known as Nitro This team was also packed in giftset MS-05 with Silverstreak (Blurr). The Street Speed Team are the only Minicon team not to have a Dimension-X release in Japan (The Dimension-X Street Action team is packed with Final Battle Prime & Overload)
Nightscream is a car - a purple repaint of Oval from the Street Speed Team - and comes packed with Armada Airazor The other 2 repainted members of the team - Spiral (Skid-Z) and Backtrack(Sideburn) are released with Armada Predacon. Looks much better than the original. Robot maintains the purple from the car exposing some grey on the body and upper legs, and having a green visor.
The colour on the car is a good match for the bird and the two work well together.
Nice repaint.
Nitro has red car bodywork & white robot body (common to the whole team)
The original intention was that Energon Ultra Magnus would be released with a set of Street Speed team repaints. According the Transformers Wiki this version of Oval would be Brakedown. Pictures show a burgundy car body with dark blue windows. I've not been able to find any pictures of his robot mode so I'm unable to say what colour the body parts would be.
All three Minicons in this set have major molding changes in the surface detail of their car bodies but maintain the same basic shape, TF and robot mode. In particular Oval looses his back window gaining some extra detail that starts on the roof and continues over the back of the car. His doors gain several moulded horizontal lines in them.
The car body in this case is moulded in bright light blue - hence the Japanese name - while the robot body and upper legs continue to be grey.
All 3 of these together make up probably the best set of these so far ! All 3 are very realisticly painted, you can quite easily believe you could see all 3 as real vehicles"
