  '''Titus''' was one of [[Queen Beryl]]’s high ranking [[youma]] who volunteered herself in the twelfth episode. She was also one of the few [[youma]]'s to be shown with any real personality and depth, with her adoration for [[Jadeite|Jadeite (Jedite)]] and determination to prove herself to him. Titus who was monitoring the progress of [[Jadeite|Jadeite (Jedite)]] suggested that he may use her help. Initially reluctant, [[Jadeite|Jadeite (Jedite)]] was impressed with her idea of inviting human couples on a romantic cruise between [[wikipedia:Tokyo|Tokyo]] and [[wikipedia:Yokohama|Yokohama]] to steal their love energy. Although the ship looked impressive, it was nothing more than a figment of the imagination of the [[youma]] and [[Jadeite|Jadeite (Jedite)]] and in reality, it was a wrecked vessel built out of Titus’s seawater power and used only for her scheme which was dubbed "Operation Romantic Cruise”. [[Jadeite|Jadeite (Jedite)]] disguised himself as the ship's captain, while Titus was disguised as his first mate. Constant advertisement and promotions of the romantic cruise proved too much for [[Sailor Moon|Usagi (Serena) Tsukino]] as she gave into the temptation of taking part in the cruise. To do this she was determined in entering a competition to take part in the cruise but was upset at [[Sailor Mars|Rei (Raye) Hino]] who unfairly won the competition and invited [[Sailor Mercury|Ami Mizuno (Amy Anderson)]] instead. A jealous [[Sailor Moon|Usagi (Serena) Tsukino]] sneaks on board the ship as a photographer, and brings [[Luna]] with her. [[Luna]] had bad feelings of the ships captain ([[Jadeite|Jadeite (Jedite)]]) and this was confirmed when they witness the captain ([[Jadeite|Jadeite (Jedite)]]) and his first mate (Titus) mysteriously disappear in the captain's cabin after inspecting a strange looking machine which was used to collect the love energy of human couples with dates. The strange looking machine is activated once romantic energy has reached its maximum peak. Consequently, Titus and [[Jadeite|Jadeite (Jedite)]] asked all of the passengers to go to the reception hall for a spectacular (twilight) extravaganza. When everyone was inside, Titus and [[Jadeite|Jadeite (Jedite)]] got out of their disguises and Titus with the aid of the strange looking machine began collecting everyone's energy using a disco ball high above the room. The device only gathered love energy to those with dates, however, so [[Sailor Mercury|Ami Mizuno (Amy Anderson)]] and [[Sailor Mars|Rei (Raye) Hino]] were unharmed. Titus sent her water monsters (disguised as crew members) to destroy [[Sailor Mercury|Ami Mizuno (Amy Anderson)]] and [[Sailor Mars|Rei (Raye) Hino]], but luckily, [[Sailor Moon]] arrived just in time. Titus lunged at [[Sailor Moon]] and pushed her out of a window, then began attacked her by manipulating the sea water into columns which was hurled at [[Sailor Moon]]. As [[Jadeite|Jadeite (Jedite)]] joined in to watch the fight, [[Sailor Mercury|Ami Mizuno (Amy Anderson)]] and [[Sailor Mars|Rei (Raye) Hino]] transformed into [[Sailor Mercury]] and [[Sailor Mars]]. [[Sailor Mars]] destroyed the crew members with her Fire Soul (Mars Fire Ignite) attack and then with [[Sailor Mercury]], went to help [[Sailor Moon]]. [[Sailor Mercury]] used her Sabão Spray (Mercury bubbles) attack to confuse Titus and [[Sailor Mars]] used her Fire Soul (Mars Fire Ignite) attack to incapacitate Titus. The Fire Soul (Mars Fire Ignite) attack gave [[Sailor Moon]] the opportunity to finally defeat the [[youma]] with her [[Moon Tiara Magic|Moon Tiara]] attack. Once she was destroyed, the ship returned to its normal form, and all of the energy-drained passengers were revived. 
  Upon reporting back to [[Queen Beryl]], [[Jadeite|Jadeite (Jedite)]] was grilled for having another plan foiled and for the unsuccessful use of her best [[youma]] Titus. This eventually leads to his ultimatum.
