Problem: Background: A marching band is a group in which instrumental musicians perform while marching, often for entertainment or competition. Instrumentation typically includes brass, woodwind, and percussion instruments. Most marching bands wear a uniform, often of a military style, that includes an associated school or organization's colors, name or symbol. Most high school marching bands, and some college marching bands, are accompanied by a color guard, a group of performers who add a visual interpretation to the music through the use of props, most often flags and rifles.
Context: Many bands have auxiliaries that add a visual component to the performance. For ceremonial bands, this could be a traditional color guard or honor guard. For drum & bugle corps and corps-style field bands, this could include Dance lines, majorettes, Auxiliary units may be collectively referred to as color guard or visual ensemble.  Auxiliaries may perform as independent groups. In the early 1970s, color guards began to hold their own competitions in the winter (after the American football season, and before the beginning of the summer drum and bugle corps season). These became known as winter guard. There are also numerous dance competitions in the off-season.  The color guard of a marching band or drum and bugle corps may contain sabers, mock rifles, and tall flags. In modern bands, other props are often used: flags of all sizes, horizontal banners, vertical banners, streamers, pom-poms, even tires, balls, and hula hoops or custom built props. The color guard may also employ stage dressing such as backdrops, portable flats, or other structures. These can be used simply as static scenery or moved to emphasize block drill, and are often used to create a "backstage" area to store equipment and hide personnel.  While military color guards were typically male, band color guards tend to be primarily female, though it is becoming more common for men to join as well. A few independent units are all-male. Guard members nearly always wear a special uniform or costume that is distinctive from that of the band, not necessarily matching in design or color. The men's and women's guard uniforms are usually designed in one of two ways: nearly identically, but with gender-specific parts (i.e. skirts) adapted for the use of the opposite sex; or complimentarily, with the two uniforms designed similarly but with variations in color or form. The color guard uniform, especially in a high school marching band, need not be in school colors; in fact, they rarely are. These uniforms are designed to represent a certain aspect of the halftime show, characterize the guard members through costumes, or tell some sort of story, and can thus be in any design or color (a surprisingly common complaint among the high school audience is that guard uniforms and equipment "aren't school colors").  Indoor color guards have become popular within high schools and universities throughout the United States. These groups perform a theme-based show in competitions after the outdoor marching band season ends. Indoor color guard shows are typically performed in school gymnasiums and are adjudicated.

Background: Leonardo, nicknamed Leo, is a fictional character and one of the four main characters in Teenage Mutant Ninja Turtles comics and all related media. He is often depicted wearing a blue eye mask. His signature weapons are two katanas. Leonardo is the most serious, the most spiritual, the most disciplined, and the most in-line with Splinter's teachings and thoughts, and is the leader of the Turtles.
Context: Leonardo again leads the team in Nickelodeon's 3D computer-animated series. He was voiced by actor Jason Biggs up until "The Wrath of Tiger Claw", Dominic Catrambone for the remainder of the second season and Seth Green beginning in the third season. In this latest version, Leonardo seems to be more experienced and still perfecting his fighting skills and leadership abilities to make more solid decisions and gain more trust from his three younger brothers. He regularly watches an animated science fiction show called Space Heroes (a parody of Star Trek: The Animated Series) and uses it as a guide for his leadership skills, often attempting to quote from the show in an attempt to sound intimidating and heroic, even if most of his attempts fall flat due to him sounding overly cliche.  Leonardo immediately developed romantic feelings for Karai since their first encounter, even though she is his adoptive sister by Splinter; she was taken in by the Shredder after her mother's death and was tasked with destroying her birth family (including Leo) before changing sides upon discovering her true heritage as his adopted sister. His weapons here are purely dual katanas, which he uses in the Niten Ryu style of kenjutsu, making him an excellent swordsman. Despite the fact the other three turtles have added traits in this series, Leonardo is almost completely normal but now has blue eyes. Upon the sudden demise of his adopted father and master, he reluctantly steps up as sensei in addition to being leader, which puts even more pressure on him. He is visited, on occasion, by the spirit of Splinter who encourages him to lead his family and friends to stopping new evils.  In addition to his natural ninjitsu skills, he eventually developed the strong innate ability to heal via an enchanted mantra known as "the healing hands." By chanting the incantation and making the right hand seals, Leo is fully capable of revitalizing his inner strength and counteract even the most lethal of poisons and venom of "the healing hands." He managed to develop and utilize it to counteract the lethal venom of Karai, and attempted to use it on her to release her from the Shredder's control but failed. He then succeeded in saving Casey and Michelangelo from death. According to Splinter, he shows great gifts as a healer, and that being at the edge of his life had given him "a power that few martial artists can tap."
Question: Did Leonardo become more brave in the series?
