Smack Studio / The Molten Express
The Molten Express (abbreviated here as T.M.E.) is a unique combination of a both a rushdown character and a heavyweight fighter. Its movement and attack speed are top notch, featuring the fastest movement and attacks in the game. In addition, it has the best defence in the game and has many of the strongest attacks in the game. However, T.M.E. is not without fault. Its recovery is particularly bad, being the slowest in the game and having poor vertical hieght gain. It is also one of the largest characters, making it quite easy to combo.
T.M.E.'s movement is very unique. It has the fastest run speed in the game, and the fastest air speed in the game. The defining stat, however, it its incredibly low friction. It slides a very far distance before stopping, allowing for the transfer of running momentum into an attack. The downside of being unable to stop is also nullified, thanks to its incredibly fast dash attack that stops all momentum.
T.M.E. has many combo starters, with Jab 1, Down Tilt, and Dash Attack all leading to multiple different followup options. Forward Tilt, Forward Strong, and Up Strong are all great kill options, with the latter two being almost as strong as some ultras.
