In Pikmin Evolution
The Gelalix is a species of cell puddle appearing in Pikmin Evolution. It is a pale white amorphous organism made of a silicon-like substance, it also has a single golden nucleus in it's main body. The Gelalix appears as a common reoccurring boss in the game, appearing in a variety of damp cavernous areas, but it particularly has a liking for living in sewers and waterways. The Gelalix, like it's older relative the Goolix, attempts to drown Pikmin with it's gelatinous body, however unlike it's fellow cell puddle family member it's body doesn't have water-like qualities, meaning that they can drown all Pikmin types. At first the battle plays out quite standard, with the Pikmin needing to attack the gel body of the Gelalix and reveal it's golden nucleus to attack it. Since the body has the same viscously as gelatin, Pikmin will only drown if the Gelalix actively smothers them in it's body. However when it loses a large amount of health the Gelalix will become more hostile and gain new abilities. Primarily it will form a crystalline shell over it's body which both makes it immune to any direct attacks and will gain the ability to mold into one of three different shapes, that being a sphere, cube, and pyramid. A single Gelalix will only change into one shape, though some may be able to change into all three shapes, and all have different counterplay. When formed into a ball it will try to roll into the Pikmin army, crushing them, often they can charge up their roll attack to perform a straight dash attack, though if it hits a hard surface the shell it forms will shatter turning it back into it's normal form. As a cube it will try to jump to the location of the captain similar to a Wollywog, crushing any Pikmin in it's way, though if it hits an explosive it's shell will shatter and the Gelalix will once again become vulnerable. Finally as a pyramid the Gelalix will spin around like a top, slicing any Pikmin in it's way, killing them, it's the strongest on even terrain so luring on rougher terrain will cause it to tip over and have it's shell shatter. These varied battle tactics makes the Gelalix a very dynamic and dangerous enemy to face-in game, but the rewards are worth it as the Gelalix will has a piece of refuce dislodge from it's gold nucleus for you to collect when it is eventually killed.
