Nightcrawler was the first, but his appearance frightened the newcomer and she phased through the controls into the Danger Room. She is caught by Colossus and comforted by the others, except Wolverine. It seemed he did not feel the young girl was up to being an X-Man.
At that time a red alarm went off signaling a mutant threat. Cyclops, Colossus, Storm, and Dazzler got into the Blackbird while Wolverine and Nightcrawler followed in a smaller jet. Together they flew off towards the Deep Space Observatory.
Meanwhile, at the Observatory Pyro and Blob had hostages while searching for coordinates for the Scorpio Comet. The X-Men arrived and Colossus attempted to attack Blob without success. Pyro attacked the heroes but Storm counters with wind. When the fires died down there were no sign of either villain. Police show up outside so the heroes left before they were blamed for the attack.
The X-Men arrived back at the mansion and pulled Xavier out from under a pile of rubble. Kitty woke up to find Nightcrawler staring down at her. She freaked out but was comforted by Dazzler. Kitty got into an argument with Wolverine before she wondered where Xavier was. Xavier showed that he was alright.
Xavier then used his powers to find discover what Magneto was doing. On Asteroid M Magneto had successfully installed the Mutant Power Circuit and was diverting the Scorpio Comet towards Earth. It would have killed most of the human race so that mutants could rule. The power of the energy involved knocked Xavier to the ground.
Xavier told his X-Men of Magneto's plan and that they had to stop it. Kitty wanted to come but both Wolverine and Xavier agreed that she should stay as she had not been trained yet. Kitty refused to be left behind and followed.
The Blackbird made its way to Asteroid M while listening to a news broadcast on the comet. The X-Men got into Space Suits and found an airlock. After they were gone Xavier asked Kitty to come out, knowing she's been there the entire time. Kitty insisted that she go along, as it's her planet to.
Cyclops blasted his way through the airlock and told Storm to help keep the atmosphere in while Wolverine tracked down Magneto.
The X-Men encountered Pyro so Dazzler decided to take him on. The X-Men go on without her until Toad surprises and attacks Wolverine. The other X-Men continued on.
When the comet was diverted towards the asteroid, and the Brotherhood left for Earth, all the X-Men excluding Nighcrawler headed back towards the Blackbird.
Xavier kept the Blackbird on a viewscreen that Nightcrawler could see. Xavier told him that he must teleported aboard at the very last second. Unfortunately Nightcrawler waited too long and the comet hit the asteroid.
Luckily Nightcrawler did teleport away but into the vacuum of space. But he was entering the atmosphere and would have burned up. The X-Men hurried to get the grappling beam on him. Nightcrawler disappeared just before the beams could latch onto him. They heard a banging noise from the back and went to investigate to find Nightcrawler alive and well.
Kitty thanked Nightcrawler for his heroism. Storm asked Wolverine if he was wrong. He said that Kitty is still no X-Man. Not yet anyways.
Wolverine has razor sharp adamantium claws. He has heightened senses that he uses for tracking. Cyclops asked him to help them track Magneto when they entered Asteroid M.
Though unmentioned, he has a healing factor which allows him to heal after he retracts his claws.
Wolverine is voiced by Neil Ross. Ross previously voiced Wolverine on Spider-Man and His Amazing Friends, both times with an Australian accent. This was due to the actor and director misunderstanding a line in the script. Wolverine calls the Australian mutant Pyro "dingo", and rather than take that as an odd Australian slur, they assumed Wolverine to be Australian. Although in the episode he actually calls Toad a dingo. The Australian accent is a common point of contention with the episode as Wolverine is traditionally Canadian.
Neil Ross previously voiced Green Goblin and Wolverine on Spider-Man and Spider-Man and His Amazing Friends while going on to play Puppet Master, General Krang, Doctor Doom, Super Skrull, Fin Fang Foom, Yinsen, Blizzard, an anchorman, Norman Osborn/Green Goblin in the MAU.
