After the apparent death of Superman, Batman saw an individual dressed like the Flash appear before him in the Batcave. Insisting that he knew him, the individual urged Batman meet with Barry Allen before disappearing. Urged by his suspicions, Batman uncovered a button in one of the walls and met with Allen. Deciding to investigate this together, they began to suspect that ramifications to the timeline might have not been caused by Barry, but another influence. At some point, he discovered the Joker was still alive and captured the Clown Prince of Crime, holding him in the Batcave to help investigate the truth of Nth.
Batman's body armored costume incorporates the imagery of a bat in order to frighten criminals. The details of the Batman costume change repeatedly through various decades, stories, media and artists' interpretations, but the most distinctive elements remain consistent: a scallop-hem cape; a cowl covering most of the face; a pair of bat-like ears; a stylized bat emblem on the chest; and the ever-present utility belt. Finger and Kane originally conceptualized Batman as having a black cape and cowl and grey suit, but conventions in coloring called for black to be highlighted with blue. Hence, the costume's colors have appeared in the comics as dark blue and grey; as well as black and grey. In the Tim Burton's Batman and Batman Returns films, Batman has been depicted as completely black with a bat in the middle surrounded by a yellow background. Christopher Nolan's The Dark Knight Trilogy depicted Batman wearing high-tech gear painted completely black with a black bat in the middle. Ben Affleck's Batman in the DC Extended Universe films wears a suit grey in color with a black cowl, cape, and bat symbol.
However, it was not as black as the "Troika" costume. This was more like the approach of the "Batman: The Animated Series" Batman, with a large bat symbol, dark gray legs and shirt and black everything else (with the utility belt maintaining the pouch look, but also adding a bit of color to the proceedings). This was basically the costume that made its way into the "Justice League" cartoon series and lasted most of the decade in a time when people were changing costumes like crazy. It's really the closest we have to the "ultimate" Batman costume.
One of the first suits we see from Christopher Nolan’s Batman Begins is Bruce Wayne’s League of Shadows training garb. While mostly built for ease of movement and warmth, the uniform also includes the armor bracers and triangle blades which are present in most bat suits, which is why we count it as a prototype of sorts. This was a great suit because we got to see that Bruce was obviously taught how to use minimal weapons and tricks, but could if need be.
