Question: Does anyone know why Gambit was featured less and less in episodes as the show went on? He was one of the most popular characters in not just X-Men, but all of Marvel Comics around the time this series first aired, so unless it had something to do with his voice actor's contract, it seems odd they wouldn't have utilized him more.
Answer: Chris Potter, the original Gambit voice actor, did indeed quit the role in the 4th season. His last episode was The Phalanx Covenant Part 1 so it seems reasonable that Fox would limit the use of the character even though it was recast. It doesn't appear that Potter left the role due to animosity, he stated in an interview that he wished to play Gambit in the first live action X-Men film.
Question: Is Dr Vink a villain? In the episodes he's in, he always seems to put innocent people in danger.
Answer: I think of him as an antihero. He can be nice and helpful at times, but he usually has ulterior motives.
Question: Why is Ursula in this show portrayed differently to how Phoebe's twin is on Friends? They're meant to be the same character.
Answer: Just think about your own life, I am sure you do not act the same with your siblings or close friends as you do with a stranger (because that is what the Buchmans essentially are to Ursula). In Mad About You, she is an extremely bad waitress and in Friends she is a jerk - those are not mutually exclusive character traits. This can also be seen in the Friends episode when Jamie and Fran are in Central Perk and run into Phoebe who answers their questions in an aloof manner and they assume it's Ursula. Is Phoebe always aloof? No. But she was to strangers asking her weird questions. Also, Ursula has been aloof with Phoebe as well (like in the one where they all turn 30 or the one where the grandmother passes away, etc).
Answer: The writers have the freedom develop the character to suit the different shows' plots. They wanted to create a certain dynamic between Phoebe and Ursula that was rather contentious and strained because it made for more tension and conflict and showcased the differences that kept the sisters estranged.
Question: Two questions. 1. Was there some kind of contributing factor that made Nick want to be human again and if so what was it? 2. In one episode Janette is discovered to be human again. How did she accomplish this?
Answer: Nick was sick and tired of being an immortal bloodsucker. He wanted to be human, fall in love, get married, have children, grow old and die. As for Janette, according to her, she fell in love and the passion she felt "cured" her of her blood lust.
Question: In all the Highlander movies and in this show, was there any reason given why immortals can't fight each other on holy ground?
Answer: In the episode "Little Tin God," Joe Dawson mentions a duel between immortals on a temple in Pompeii—just before Vesuvius erupted. Whether the two are supposed To Be connected is up for debate, but still.
Answer: Not directly. But there is a penalty involved. In Highlander 3 the fighting on holy ground resulted in the destruction of one of the weapons. In End Game several immortals are murdered whilst on holy ground but no repercussions were ever revealed, so it's possible it is specifically about the fighting. Nobody knows what happens when an immortal is killed in a duel on holy ground but it's safe to assume the penalty will be severe because all immortals respect this rule, even the most evil ones (except that one moment in Highlander 3).
Answer: Because he stole a chemical from his lab.
But Batman knew that with it, Clayface could permanently retain his shape and Clayface desperately wanted to be Matt Hagen again. In a sense, Batman stopped Clayface from becoming human.
