Grant McFarland not only portrayed Lothor but also the Sensei in Power Rangers Ninja Storm. He is from New Zealand. On PMC 4, Doug Sloan said that Grant McFarland was devastated that fans didn't like his character of Lothor, that fans found him too goofy. So when he returned for "Thunder Storm" in "Dino Thunder," he decided to portray the character darker. Doug Sloan did not think it was necessary. Some fans did notice and liked the darker tone. I think it would make sense since he was in the Abyss of Evil.
