* SugarWiki/AwesomeMusic:
** "Time For L-Gaim" is a beautiful synth-pop theme that just ''screams'' 80s, but in a really '''good''' way. [[https://www.youtube.com/watch?v=hQmBY_XseDM L-GAAAAAAAAAAAAAAAAAAAAAIM!]]
** "Kaze no No Reply", the second opening theme, ain't half bad either. [[https://youtube.com/watch?v=dw79lC01gZ0 Say Mark-2!]] It helps that it's sung by Mami Ayukawa, who's also known for [[Anime/MobileSuitZetaGundam Z Toki wo Koete]] and [[Anime/MetalArmorDragonar Yume Iro Chaser]].
* CompleteMonster: Emperor [[BigBad Oldna]] [[UltimateLifeForm Poseidal]] built the forces of [[TheEmpire the Poseidal Empire]] until he launched a brutal campaign of conquest and extermination to enslave or destroy all in his path. Exterminating his old enemies, the Yaman Clan, save for a few members, Poseidal sets up a brutal dictatorship, [[spoiler:using his former lover as a fake Poseidal by [[BrainwashedAndCrazy brainwashing her and having her commit atrocities in his name]]]], with torture, murder and extermination being commonplace. [[spoiler:He then took the name of ArmsDealer Amandara Kamandara and began to [[PlayingBothSides supply weapons to both sides]] to keep the conflict going, making it even bloodier, so he can remain in power. When he reveals himself at the end, Poseidal gleefully attempts to annihilate all rebel forces, [[BadBoss uncaring that this will kill many of his own soldiers as well]].]]
* FanNickname:
** Due to its resemblance to L-Gaim, a white Gundam from Mamoru Nagano's Newtype Magazine MSV series is nicknamed Heavy Metal L-Gundam.
** Fans often refer to [[spoiler:Poseidal's AceCustom]] as "Original Auge" to distinguish from Nei's machine.
** Usually, different romanizations are used to differentiate machines from this series with their counterparts in ''Five Star Stories.'' ''L-Gaim'''s A-TAUL vs. A-toll from ''FSS'', Bat-Shu the Blue Knight vs. Vatshu the BlackKnight, etc.
* FashionVictimVillain: Emperor Poseidal. It takes a special kind of person to wear curtain-rods as epaulets.
* HilariousInHindsight: This wouldn't be [[Series/KamenRiderGaim the last time]] Creator/HochuOtsuka would be involved with a series with "Gaim" in it's title.
* SpiritualAdaptation: ''Manga/TheFiveStarStories'' is essentially a comic prequel[[note]]and sequel, and interquel[[/note]] to ''L-Gaim''.
