'''"Two Planets Approach the Roche Limit"''' is the final boss battle theme of ''[[Kirby and the Forgotten Land]]'', used for the battles against [[Fecto Elfilis]] and [[Chaos Elfilis]]. It was composed by [[Hirokazu Ando]],<ref name="composer"></ref> and can be found as track 71 at the [[Jukebox/Kirby and the Forgotten Land|Waddle Live! Corner Stage]].

==Composition==
[[File:KatFL Fecto Elfilis Fight screenshot 05.png|left|thumb|200px|The Ultimate Life-Form themselves.]]
"Two Planets Approach the Roche Limit" can be seen as two themes, one for each phase of the fight. The song as a whole is set in a 6/8 time signature at about 130 beats per minute.

The first part of the song is in E flat major, and is around four minutes long. It features predominantly violins, but also female choir, triangle, bells, organs, and a bit of percussion. Most notably, however, it rarely uses patterns, creating a more chaotic or improvisational feeling. Several other melodies can be heard, like "[[Welcome to the New World!]]", "[[Running Through the New World]]", and "[[VS. Dangerous Beast]]". One part sounds similar to "[[The Battle of Blizzard Bridge (theme)|The Battle of Blizzard Bridge]]", though it's unknown if it was intentional.

Once Fecto Elfilis has 40% health left, they will switch to the second phase as the music smoothly transitions to the second part of the song, syncing up with their "Space Debris" attack. However, Kirby can do so at nearly any point of the battle, and by extension at any point during the theme. As a result, "Two Planets Approach the Roche Limit" is an interactive piece of music that has 14 unique transitions between phases, with the version heard at the Waddle Live! Corner Stage using the 14th transition. During the battle with Chaos Elfilis, the transitional interlude kicks in once the time comes for Kirby to use [[Dome Mouth]] at the end of the first phase. The second phase of that particular fight starts with "[[Eternal Echo of the Thrilling Tour-our-our]]", but the second phase of "Two Planets Approach the Roche Limit" kicks in when 70% of their health or lower is left and they attack with "[[Deadly Sun|Deadly Sun Grazer]]".

The second part is very hard rock-like, with leading instruments changing to electric guitar and trumpets, the drums changing to double time, and the key jumping to G flat major. This part loops until the battle is over. Overall, this part of the song is similar to "[[Suite: The Star-Conquering Traveler|Suite: The Star-Conquering Traveler ~ Fourth Movement: Hope of Birth]]", another final boss theme that Hirokazu Ando composed.

==Etymology==
The theme's name refers to Fecto Elfilis's attempt at making [[Popstar]] and the [[new world]] crash into each other upon being defeated. The [[wikipedia:Roche limit|Roche limit]] is the smallest distance between two objects at which one object's gravitational binding force at least matches the tidal force exerted by another object (i.e., the differential in gravitational force exerted by the latter along the length of the former); by crossing the Roche limit, the former object would disintegrate. By implying that the two planets are approaching a mutual Roche limit, the title suggests that Popstar and the new world would tear each other apart. The same terminology is also used for the French, Dutch, Italian, German and Spanish titles.

In Japanese, the theme is called '''いつしか{{furi|双星|そうせい}}はロッシュ{{furi|限界|げんかい}}へ''' (''Before One Knows, The Double Stars Will Go to the Roche Limit''). 双星 means "[[wikipedia:double star|double stars]]", which are stars that look like they are close to each other when observed from Earth, either by coincidence or due to forming an actual binary system. A notable example of a double star is [[wikipedia:Antares|Antares]], the namesake of Fecto Elfilis's spear.<ref>''Kirby and the Forgotten Land Perfect Support Guide'', page 359</ref> 双星 can also mean "diaster", which is a stage in [[wikipedia:Mitosis|mitotic cell division]] in which the divided and separated chromosomes group themselves near the poles of the spindle preparatory to forming new nuclei. Thus, 双星 here is both referring to the new world and Popstar going to crash to each other, but also of [[Elfilin]] and [[Fecto Forgo]] fusing with each other to form Fecto Elfilis. The same terminology used for the Japanese title also applies to both the Chinese and Korean titles.
