Teenage Mutant Ninja TurtlesEdit
For further information, see the Turtlepedia article for Leonardo.
Donatello, April O'Neil, and Harold Lillja gathered everyone to test their Interspatial Teleportation Unit. Leonardo was curious about the call and learned Donatello wanted to do a serious field test. As they all went through the portal, Harold accidentally hit a switch marked "Spatial Dimension Do Not Touch."
Leonardo recognized the statuary and windows from the church they used as their lair and realized they were transported to another dimension instead of time shifted. Bound by honor, Leonardo refused to issue a retreat and wanted to deal with the newly freed Chi-You. Leonardo deferred to Michelangelo but he didn't understand Chi-You's language so Leonardo advised everyone to hold their ground. As soon as Chi-You shot at them, Leonardo reversed the order. Now faced with several remotely Possessed Humans, Leonardo ordered his brothers to only incapacitate and restrain. Leonardo was very cordial with the Ghostbusters and voiced his appreciation of their help. He mistook Winston Zeddemore for the leader but nonetheless the two bonded over the shared responsibility of "herding" their comrades like cats all the time. When word of an attack on the Madison Square Garden reached the Ghostbusters, Leonardo was adamant about helping Casey rather than staying behind to work on another teleportation unit.
Like clockwork, Leonardo found himself trying to keep his brothers focused. Michelangelo was enamored with the Ecto-2 and Donatello was gung-ho with using his Proton Pack. Upon entering the Madison Square Garden rink, Leonardo noticed the correlation between Chi-You changing humans into thralls and becoming weaker. In the Chinatown battle, Leonardo tried in vain to dissuade Raphael from deviating from the plan of zapping the thralls only. With Casey Jones back to normal, Leonardo promised the Turtles would stay until the last possible moment to help the Ghostbusters with capturing Chi-You rather than leave once the Interspatial Teleportation Unit was completed.
Leonardo waited for the teleporter and Electromagnetic Pulse Emitter's completion with Raphael, Michelangelo, Peter, and Winston. He allowed Winston to inspect one of his katana and was glad someone appreciated its perfect balance. When the proximity alert was triggered by the Thralls, Leonardo and Raphael took the fire poles down and strapped on the Arm Mounted Proton Packs. Once the Thralls were neutralized, Leonardo made his way back upstairs. He retrieved Winston's Trap and tossed through the six inch gap between Peter and Winston. Chi-You refused to be defeated and possessed Winston. After knocking Ray out and punching Michelangelo, Chi-You rammed Leonardo through the wall. Leonardo and Raphael charged Chi-You but were slammed into each other. Michelangelo doused Chi-You in positively charged Psychomagnotheric Slime and weakened his hold. Raphael distracted Chi-You while Leonardo shocked Winston with his pack attachment. As Peter trapped Chi-You, Leonardo and Raphael helped Winston up. As the two teams parted ways, Winston gifted Leonardo with his two lucky Sergeant patches. Leonardo accepted and bowed.
