BullTrain's main ability consisted of combos using their fists, building up steam that could be released through other attacks. They also would've been able to attack with headbutts, set down railroad tracks to damage enemies, and turn into a full train to run across them.
Trivia
BullTrain’s soul gem "Turning Red" is a reference to how bullfighters wave a cloak (usually red in color) to agitate a bull; it's a disproven myth that the color red is what agitates the bull, as bulls are colorblind.
The concept of BullTrain being a mechanical bull may reference rideable mechanical bulls often found in taverns and clubs.
BullTrain's name may derive from "bullet train".
A piece of concept art of BullTrain can be found in the early pages of the Skylanders: SuperChargers Clutch artbook.[2]
