Mega Man Xtreme 2 is the second and last entry of the handheld spin-off Mega Man X series, and was released on the Game Boy Color on July 2001 in Japan, October 2001 in North America, and February 2002 in Europe. Chronologically it takes place sometime between the events of Mega Man X3 and Mega Man X4, and includes enemies and gameplay elements from Mega Man X, X2, and X3.
In the year 21XX, reploids across the globe are having their programming and personalities suddenly erased, leaving them as hollow and lifeless shells. The phenomenon was named "ERASURE", and eventually led X and his partner, Zero, to Laguz Island to discover what is the cause of the event.
With assistance from Iris, a recent addition to the Maverick Hunter team by Repliforce, X and Zero make it to the island to discover a number of their old enemies have been mysteriously revived as guardians of the island. They are then confronted by Berkana and Gareth, self-proclaimed Soul Erasers who have been using the DNA Souls of reploids to become the most powerful reploids in the world, and are eager to test their newfound powers against the legendary Maverick Hunters, X and Zero.
Mavericks (X Mission):
- Neon Tiger gives the Ray Claw to X, and Rising to Zero.
- Launch Octopus gives the Marine Tornado to X, and Fish Fang to Zero.
- Volt Catfish gives the Tri-Thunder to both X and Zero.
- Flame Mammoth gives the Fire Wave to both X and Zero.
Mavericks (Zero Mission):
- Wire Sponge gives the Strike Chain to X, and Lightning to Zero.
- Blast Hornet gives the Bomb Bee to X, and Earth Gaizer to Zero.
- Overdrive Ostrich gives the Sonic Slicer to X, and Dash to Zero.
- Tunnel Rhino gives the Tornado Fang to X, and Drill Crush to Zero.
In Extreme Mode, all eight Mavericks from the previous two missions can be fought in any order with either X or Zero, although only the character who actually beats the Maverick gets their weapon.
By beating Extreme Mode, Boss Attack Mode becomes accessible, in which X or Zero can face all the Maverick bosses of this game, or the eight Maverick bosses of Mega Man Xtreme, in succession while being timed.
- All There in the Manual: Haruki Suetsugu designed Gareth to have a Reploid lion companion that was never featured in the game. The designer jokingly begs the audience to just assume the lion follows Gareth around faithfully, but not in any way that is visually confirmable within the game.
- The Compendium of Rockman X source book (released only in Japan) reveals that Gareth was created by Berkana.
- Animal Motifs: Sigma's final form has a lion motif.
- Back from the Dead: Eight Mavericks from the first three games have been resurrected to guard the island from intruders.
- Bag of Sharing: Played straight and averted. Upgrades and Sub-Tanks are usable by both X and Zero, however special weapons are only gained by whichever one lands the finishing blow on the enemy Maverick.
- Barrier Change Boss: Sigma can change his defenses so that he is either invulnerable to X's attacks but susceptible to Zero's, or vice-versa.
- Battle Ballgown: Berkana sports a full-length gown, complete with golden spikes along the trim and hover technology. Justified in that she's a Reploid made to look like a witch.
- Black Knight: Keeping in the medieval theme set with Zain and Geemel in Xtreme, Gareth is crafted to look like a classic knight.
- "Blind Idiot" Translation: "Reploid Research Lavatory," anyone?
- Boss Rush: In Extreme Mode, as well as in Boss Attack Mode, in which X and Zero can fight all the Mavericks from this game, or its predecessor, Mega Man Xtreme.
- Colour-Coded for Your Convenience: Sigma's colors change based on his current vulnerability to attacks; green means he is susceptible to both X and Zero, blue means he can only be damaged by X's weaponry, and red means he can only be harmed by Zero's attacks.
- Continuity Nod: The Maverick Hunters and Repliforce working together, as this game is set between Mega Man X3 and Mega Man X4. Repliforce's Iris is working as X and Zero's navigator on her first assignment, and at the end of the game, Zero mentions Colonel.
- On the other side, despite being a spin-off franchise, the "ERASURE" incident is mentioned in Mega Man X6.
- Convection Schmonvection: An electrified Giant Wall of Watery Doom is instant-death, but the damage done by a wave of molten lava is a minor inconvenience at best.
- Death Course: Several throughout the game, whether it be a Giant Wall of Watery Doom into Death Spikes, or an electrified instant-death version of said water wave. Interesting enough, a wave of lava is not an automatic death in this game.
- Disc-One Nuke: Although it'll take some DNA Soul grinding, X can from the start equip the upgrades of Buster +1, Buster +2, Speed Shot, and the Ultimate Buster. After doing this and turning Rapid Fire on, X can launch an endless stream of superpowered, fully charged plasma blasts that can make short work of just about every enemy in the game!
- Do Well, but Not Perfect: To use the aforementioned Disc-One Nuke, X must not complete his armor upgrades, since as soon as he does he is limited to only two additional upgrades instead of four. This does mean skipping the Shoryuken and Hadoken though.
- Giving either X or Zero all the Heart Tanks and Special Weapons while playing in Extreme Mode can leave you with a severely crippled character when you face the Final Boss, which requires both characters to be able to defeat, since it switches immunity/vulnerability between X and Zero's attacks. This is especially true for Zero who, without certain special weapons, cannot obtain his armor defense upgrade or ultimate attack.
- Empty Shell: Reploids who have had their programming/souls erased are described as becoming like hollow shells.
- God Save Us from the Queen!: Although Berkana is made to look like a witch, she has several queenly attributes, from sitting on a throne to acting as the self-proclaimed leader of the Soul Erasers. She's also quite unapologetically evil, using the souls of countless Reploids to strengthen herself and her Black Knight.
- Hijacked by Ganon: In Extreme Mode, after beating either Berkana or Gareth, Sigma comes out of nowhere and claims he was the one responsible for the entire "ERASURE" incident. He does, however, admit that Berkana had gone too far, but was fine with that since in the end it amused him.
- Hot Witch: Berkana is modeled after a witch of sorts, although a rather good looking one for a Reploid.
- Hover Mecha: Berkana never seems to touch the ground, instead hovering through the use of her Battle Ballgown. She does seem to have legs, however, as one shot of her shows an outline of her legs crossed while sitting.
- For the R25 Complete Works artbook, Haruki Suetsugu includes her in his contribution page. Not only is she drawn with one of her feet visible, but she actually says "I do have legs under this dress, just so you know".
- Interface Screw: Berkana's attacks include projectiles that can disable X's ability to jump or shoot.
- It Amused Me: The reason why Berkana doesn't try and stop X and Zero from destroying the island guardians. Also, the reason why Sigma doesn't stop Berkana, even though she has gone too far and has started acting in her own interests instead of his.
- Japanese Ranguage: The Reploid Research Lavatory is obviously a mistranslation of the Reploid Research Laboratory.
- Javelin Thrower: Gareth's attack of choice, either throwing his Laser Javelin while off-screen, or up close at point-blank range.
- Luckily, My Shield Will Protect Me:
- New Game+: When either X or Zero complete their mission mode, the save file can be played again through the other's mission, with the previous hero's Maverick weapons unlocked and collected DNA Souls retained.
- Our Souls Are Different: The stolen Reploid programming is directly compared to human souls, and Iris dubs them DNA Souls as a result. They can be used by other Reploids to empower themselves.
- Permanently Missable Content:
- Special weapons can only be obtained by the character who defeats the Maverick, so on any Extreme Mode playthrough, half the weapons are lost forever.
- If Zero skips Wire Sponge's Lightning he can never gain his arm enhancement, which gives him his ultimate attack. If he misses Tunnel Rhino's Drill Crush he loses out on his body upgrade that increases his defense.
- Promoted to Playable: Zero, in terms of the Xtreme franchise, anyway.
- Self-Deprecation: The Big Bad sets up a "game" by placing eight robot masters for the heroes to defeat before he challenges them himself. X replies that the game is pointless.
- Shoot the Dangerous Minion: Sigma thanks X and Zero for taking care of Berkana, saying she went too far and was too greedy with the power she was taking.
- Soul Power: Berkana and Gareth and possibly Sigma are stealing Reploid souls to make themselves more powerful. X and Zero can do the same thing with Maverick souls, turning them into new upgrades.
- Spikes of Villainy: The bottom of Berkana's Battle Ballgown is covered in a row of golden spikes.
- Violence Is the Only Option: While X decries Gareth's "silly games", Zero simply points out that "retiring eight may be easier than persuading one". Gareth, naturally, approves of this logic wholeheartedly.
- Your Soul Is Mine: The Soul Erasers are stealing Reploid programming (their souls) from all over the world.
