We already knew Menasor was shipping with Offroad replacing Wildrider so speculation turned to which Stunticon mould would provide the new version of Wildrider in the Japanese Menasor: Dead End or Breakdown? I could see the argument for Breakdown being used: Wildrider is more angular than Dead End but Breakdown's vehicle mode is easily identifiable as a Lamborghini so thought Dead End was probably going to be the one repainted.
On the 22nd of January 2015 a Toys R Us listing for Slingshot & Wildrider was found, leading to speculation that there would be a western release of the limb recolours as an exclusive. The long suspected Japanese version of Wildrider using Dead End was revealed in a magazine on the 20th March. On 23rd March a Diamond listing for theses toys was found with Hasbro teasing them on Facebook the next day under the names Quickslinger and Break-Neck. The full versions were revealed the day after on 25th March by which time pre orders were opening up everywhere.
Although I get that for various reasons the name Wildrider and his persona might be wanted to be avoided the name Brake Neck seems a little odd given there's already a similarly named Breakdown on the Stunticon team.
Dead End becomes the first Combiner Wars mould to be used three times with Brake-Neck. Generally the car mode for Brake-Neck looks pretty good swapping Dead End's burgundy for grey/silver but the mid arm panels, coloured red, form part of the side of the vehicle and break up the grey body work. A little bit of paint to make the line of the top of the door the same colour wouldn't have gone amiss.
Transforming to robot mode reveals more colours. The Burgundy of Dead End's chest and chest panel are the only parts of that colour not to become silver/grey, they're more of a pale grey. The pale grey of the knees, waist and combiner wars connector become black. The darker grey of the upper legs, hands, mid arm pieces, neck and combiner connector become red. A new head, featuring Wildrider's signature spikes sticking out the side is cast in a similar colour to the car body with a painted red face.
Given that an exact car match for Wildrider was unavailable this is a pretty good attempt. The red breaking up the top of the door and not quite matching the rest of the red stripe does annoy me though!
