When a video game first in the series is released, it will often have a slow, powerful fighter (known here as a MightyGlacier) or two. However, as the series increases and more characters are added, the number of these characters often stays the same, resulting in a gigantic roster with only one or two big heavy glacier guys. Hence, Global Warming.

Compare TheSmurfettePrinciple, which gives this treatment to female characters.

* Melted Glacier example: The ''VideoGame/StreetsOfRage'' series has had only one slow guy, Max, who was promptly replaced with LightningBruiser Dr. Zan and LethalJokeCharacter Roo in the third game.

[[folder: Fighting Games ]]

* ''VideoGame/BattleFantasia'' has only one glacier fighter in Donvalve.
* ''VideoGame/BlazBlue'' has Iron Tager. Hakumen is also something of a MightyGlacier, just the rare example of a character in that category being smaller than usual. The third game adds Azrael.
* ''VideoGame/DeadOrAlive'' only has 3 'big' characters who rely mainly on power and grapples: Bayman, Bass, and Leon.
* ''VideoGame/GuiltyGear XX'': Around two dozen characters and exactly one big guy (Potemkin). Eventually averted in ''Accent Core + R'', but only because the developers rebalanced former SNKBoss Justice into this so she would be tournament viable.
* ''VideoGame/TheKingOfFighters'' started with Goro, [[VideoGame/IkariWarriors Ralf, Clark]], and Chang Koehan. It took them about six years to add Maxima, a year to add Seth, three more to add Tizoc, and about another six to add [[VideoGame/FatalFury Raiden]]. Although there have been other grapplers in the series, they have generally always been {{Fragile Speedster}}s.
* ''VideoGame/MarvelVsCapcom2'' has 56 playable characters and only six are of the slow-and-strong type: Zangief, Anakaris, Colossus, Sentinel, Hulk, and Juggernaut.
* ''VideoGame/MarvelVsCapcom3'' is a teeny bit better about this with Haggar, Dormammu, Thor, and to some extent Spencer joining Hulk and Sentinel for six slow but strong characters out of 38 total. With the release of ''{{U|pdatedRerelease}}ltimate Marvel vs. Capcom 3'' and its 12 new characters, the only new additions who seem to fit this mold are [[VideoGame/ResidentEvil3Nemesis Nemesis]] and Comicbook/GhostRider, making the final ratio 8:'''50'''.
* ''MortalKombat'' handles this very oddly: every MightyGlacier in the series is a boss and is only playable in [[DreamMatchGame the]] [[VideoGame/MortalKombat3 full]] [[VideoGame/MortalKombatArmageddon cast]] games -- the only exceptions are Shao Kahn and Goro in the Gamecube version of ''[[VideoGame/MortalKombatDeception Deception]]'' and ''Unchained''.
* ''[[VideoGame/SoulSeries Soulcalibur]]'' has four "big" characters (Astaroth, Nightmare, Siegfried, Rock) compared to more than twenty others, though in this case it's because there's only so many big weapons in the world. If one is generous, Ashlotte and Kamikirimusi (two of the five bonus characters in ''IV'') count too, due to being palette swaps for Astaroth and Nightmare respectively, albiet considerably smaller.
* ''VideoGame/StreetFighterIII'' started with just Alex, added Hugo and Urien in ''Second Impact'' and finally Q in ''Third Strike'' for four out of twenty characters, which isn't too horrible.
* ''VideoGame/StreetFighterIV'''s arcade release started with three out of seventeen (Zangief, E. Honda, and Balrog). The console version made that three out of 25. ''Super'' added T. Hawk and Hakan for five out of 35. ''Arcade Edition'' takes it to ridiculous levels with five out of 39.
* ''VideoGame/StreetFighterAlpha'' has Birdie, T. Hawk and Zangief, and every other character with this playstyle is fast. Sodom and E. Honda aren't ''much'' faster, though.
* Averted in ''VideoGame/SuperSmashBros'', where the original {{Nintendo 64}} game had ONE Mighty Glacier (Franchise/DonkeyKong) out of 12 characters, ''Melee'' added two more ([[Franchise/SuperMarioBros Bowser]] and [[Franchise/TheLegendOfZelda Ganondorf]]) in a 26-character roster, and ''Brawl'' added [[VideoGame/WarioLand Wa]][[VideoGame/WarioWare rio]] (though he's more {{acrofatic}}), [[NintendoEntertainmentSystem ROB]], [[VideoGame/{{Kirby}} King Dedede]], [[Franchise/{{Pokemon}} Charizard]], [[Franchise/FireEmblem Ike]] (even though he's a LightningBruiser in [[VideoGame/FireEmblemTellius his games]]), and [[Franchise/MetalGear Solid Snake]], for a total of nine characters out of 39 total. Quite impressive.
** No new heavyweights have been announced for the [=WiiU=] and [=3DS=] versions yet (though Rosalina is very tall), but Bowser, Donkey Kong, and Dedede are larger than they were in the previous games.
* ''VideoGame/{{Tekken}}'' usually features four heavy characters: Ganryu, Jack, King, and Kuma. Marduk is also in since ''4''. Now contrast this with the character roster of ''Tekken Tag Tournament 2'' which numbers 59 in the console releases. With Armor King, Prototype Jack, and Panda, that's eight slots filling the MightyGlacier role.

[[folder: Turn Based Strategy ]]

* Non-{{fighting game}} example: There's three MightyGlacier classes in ''Franchise/FireEmblem'' (out of a dozen or so): The Generals (standard glaciers), Wyvern/Dragon Riders (flying glaciers), and Fighters/Pirates/Brigands (more of HP sponges than anything else, and the last two veer towards LightningBruiser). Generally, you only get one or two characters of each of those classes, though if the roster is really big (like in ''[[FireEmblemElibe Sword of Seals]]'' or ''[[VideoGame/FireEmblemTellius Radiant Dawn]]'') you might get three (or four for Generals), and some early games don't even feature playable Brigands. Every other physical class tends to have more characters in it, and aside from [[JackOfAllStats Paladins]], they all are of the FragileSpeedster type to a degree. Also, Dragon Riders generally come from mid-game onwards, generally the last class that will join you aside from [[DarkIsNotEvil Dark Magic users]] (justified in that [[HeelFaceTurn they're used by the enemy army]]). Considering how in ''Fire Emblem'' [[OneStatToRuleThemAll speed really matters]], limiting their numbers isn't exactly for CompetitiveBalance, so...
** The [[PettingZooPeople Laguz]] from the [[VideoGame/FireEmblemTellius Tellius]] games avert this, to a extent: In ''Radiant Dawn'' you get a handful of new Laguz besides all the old ones in ''Path Of Radiance'', and most of the new ones are Tigers, Lions, or Dragons, which are of the tanky type. Regular classes play this straight, however; in fact, the one Berserker on the first Tellius game is the only playable character not coming back for the sequel, and while you get 5 [[FragileSpeedster Trueblades]], you only get a measly two Reavers, with Sentinels and Marksmen at three each. And yes, they're all "sister" classes, each specializing in a specific weapon type.

[[folder: Wrestling Games ]]

* ''VideoGame/WWEAllStars'' features only three "Big Man" class characters: Wrestling/AndreTheGiant, Wrestling/TheBigShow, and {{Wrestling/Kane}}. DLC adds Wrestling/MarkHenry. If one is willing to be generous, one might count Wrestling/TheUndertaker and DLC's Wrestling/DustyRhodes.
