Alexander Mars (アレクサンダー・マーズ) is a Swedish competitor who competed on both seasons of Ninja Warrior Sweden and four international SASUKE/Ninja Warrior competitions.
Ninja Warrior Sweden[]
Mars began his worldwide Ninja Warrior debut in the first season of Ninja Warrior Sweden. He first competed in the third qualifying episode where he was one of 18 competitors there to finish the six-obstacle course. In the first semifinals episode, he completed the extended nine-obstacle course in the fastest time. In the finals, he was one of only three competitors to clear Stage 1. He was this close to completing Stage 2, but his run came to an end on the Cliffhanger. He was the Last Man Standing of that season.
Mars then competed on Ninja Warrior Sweden 2 in the Stockholm Region. He was one of ten finishers to complete the Regional Qualifying course. He then went on to complete the Regional Finals course as the lone finisher. In Stage 1 of the Grand Finale, he failed the Jumping Spider.
SASUKE 31[]
After becoming the Last Man Standing on Ninja Warrior Sweden, Mars went on to compete on SASUKE 31 as a representative of Sweden. He was given #84 and cleared the First Stage, although his run was cut. His run on the Second Stage was digested, but he subsequently went out on the Salmon Ladder Kudari, when the bar missed the last set of rungs.
American Ninja Warrior: USA vs. The World[]
Mars took part on American Ninja Warrior: USA vs. The World 2, representing Team Europe for the very first time. He failed the Jumping Spider on Stage One and failed the Ultimate Cliffhanger on Stage Three, and he lost both his heats.
Mars then appeared on American Ninja Warrior: USA vs. The World 3, where he would fail the Jumping Spider on Stage One twice. He would make it deep into Stage Three, however, clearing the modified Ultimate Cliffhanger, but undershot the hard left transition on the Walking Bar and failing there. He lost both his heats once again.
Mars also competed on American Ninja Warrior: USA vs. The World 4, which marked his last time competing on American soil. He failed the Wave Runner on Stage Two, and he did not earn any points for Team Europe in his first heat. He then failed the Ultimate Cliffhanger on Stage Three for the second time, but earned at least one point in his second heat.
