Note: This contains info that describes how the character is in "Eric & Yannik 5" (after "Eric & Yannik 5" got updated to version 4.1.0.2). For an older version (that only describes how the character was in "Eric & Yannik", "Eric & Yannik 2", "Eric & Yannik X", "Eric And Yannik Gotta Go", and "Eric & Yannik 5" (before "Eric & Yannik 5" got updated to version 4.1.0.2)), go here.
Yannik is a short, freckled, and cute male "humetarm" with "pale-orange" fleshy human skin, a blond spiky quiff hairstyle, blue human eyes with white sclera, and blue metallic forearms with white hands (Yannik's blue metallic forearms with white hands can turn into blue metallic arm cannons). Yannik wears a blue sleeveless leotard, and blue shoes (that are short enough to not be boots) with white socks. Yannik's primary fire is an "electricity-elemental" blue EMP grenade coming from one of his arm cannons. Yannik's secondary fire is an "electricity-elemental" blue MIRV EMP grenade also coming from one of his arm cannons. Unlike almost all projectiles, Yannik's secondary will also split into four EMP nadelets. Yannik's primary fire and secondary fire have the slowest rate of fire. Like almost all projectiles, Yannik's primary fire and secondary fire can damage enemies but are unable to stun enemies. Unlike almost all projectiles, Yannik's primary fire and secondary fire are also affected by gravity. Unlike almost all projectiles, before Yannik's primary fire and secondary fire become "electricity-elemental", Yannik's primary fire and secondary fire start out "antidarkpurpleonibi-elemental" (which has an attack power of infinite, "antidarkpurpleonibi-elemental" attacks can only hurt dark-purple onibi, and everything else is immune to "antidarkpurpleonibi-elemental" attacks) when first fired, then shortly become "antisaffronslime-elemental" (which has an attack power of 0.5, "antisaffronslime-elemental" attacks can only hurt saffron slimes, and everything else is immune to "antisaffronslime-elemental" attacks), and then become "electricity-elemental" (which the primary fire and secondary fire have attack power of 8, while the nadelets of the secondary fire also have an attack power of 8) while blowing up. Yannik's primary fire and secondary fire are fired and propelled electromagnetically. Yannik also has fast 3D printers that can print his primary fire inside his torso that activates when one of Yannik's arm cannons fire, the 3D printer being why Yannik has infinite primary fire ammo. While Yannik has infinite primary fire ammo, Yannik's secondary fire ammo is limited, but Yannik's secondary fire ammo regenerates gradually, and Yannik can have a maximum of 3 secondary fire ammo. However, dark-purple onibi can drain Yannik's secondary fire ammo. With Yannik having a primary fire "attack-power" of 8 (high) (because Yannik's primary fire (unlike almost all projectiles) is a grenade, Yannik's primary fire has a "preblowup lifespan" that is 2 seconds), a maximum primary fire "projectile speed" of 700 (low) (because Yannik's primary fire (unlike almost all projectiles) obeys gravity, Yannik's primary fire has a maximum "projectile bounce height" that is 800 (low)), a primary fire "startup delay" of 0 seconds, a primary fire "delay after firing" of 1 second (slowest), a secondary fire "attack-power" of 8 (high) (because Yannik's secondary fire (unlike almost all projectiles) is a grenade, Yannik's secondary fire has a "preblowup lifespan" that is 2 seconds), a maximum secondary fire "projectile speed" of 700 (low) (because Yannik's secondary fire (unlike almost all projectiles) obeys gravity, Yannik's secondary fire has a maximum "projectile bounce height" that is 800 (low)), a secondary fire "startup delay" of 0 seconds, a secondary fire "delay after firing" of 1 second (slowest), a secondary fire "secondary fire ammo cost" of 1.5 (Yannik's secondary fire (unlike almost all projectiles) can can split into four EMP nadelets, each nadelet having a "attack-power" of 8 (high), a maximum "projectile speed" of 700 (low), and a maximum "projectile bounce height" of 400 (low)), a maximum health of 2 (low), a maximum walking speed of 240 (low), a maximum running speed of 400 (low), a jump height of 975 (low), an "energy-elemental" damage resistance of 0 (meaning that Yannik isn't resistant to "energy-elemental" damage), an "electricity-elemental" damage resistance of 1 (meaning that Yannik is so resistant to "electricity-elemental" damage that Yannik is immune to "electricity-elemental" damage), a "physical-elemental" damage resistance of 0 (meaning that Yannik isn't resistant to "physical-elemental" damage), a "corrosion-elemental" damage resistance of 0.5 (meaning that Yannik is resistant to "corrosion-elemental" damage), a "selfharm-elemental" damage resistance of 1 (meaning that Yannik is so resistant to "selfharm-elemental" damage that Yannik is immune to "selfharm-elemental" damage), a "fire-elemental" damage resistance of 0 (meaning that Yannik isn't resistant to "fire-elemental" damage), an "antisaffronslime-elemental" damage resistance of 1 (meaning that Yannik is so resistant to "antisaffronslime-elemental" damage that Yannik is immune to "antisaffronslime-elemental" damage), a "onibi-elemental" damage resistance of 0 (meaning that Yannik isn't resistant to "onibi-elemental" damage), an "antidarkpurpleonibi-elemental" damage resistance of 1 (meaning that Yannik is so resistant to "antidarkpurpleonibi-elemental" damage that Yannik is immune to "antidarkpurpleonibi-elemental" damage), a "crate-elemental" damage resistance of 0 (meaning that Yannik isn't resistant to "crate-elemental" damage), and a "spike-elemental" damage resistance of 0 (meaning that Yannik isn't resistant to "spike-elemental" damage), Yannik is "punch-packing", but fragile and slow. Yannik's secondary fire ammo regenerates faster, and Yannik is flightless. Yannik is immune to "electricity-elemental" damage caused by his primary fire and secondary fire, and Yannik is resistant to "corrosion-elemental" damage caused by green slimes, but Yannik isn't resistant to "energy-elemental" damage caused by plasma snotters (Plasma snotters are "four-legged pig-like pink metallic cannons" that can "sneeze" an "energy-elemental" pink plasma "snot" (that is smaller than Eric's pink fiery plasma shot and as big as Mateo's purple plasma shot)), Yannik isn't resistant to "fire-elemental" damage caused by saffron slimes, and Yannik isn't resistant to "onibi-elemental" damage caused by dark-purple onibi and saffron onibi. Yannik's primary fire and secondary fire can hurt green slimes, plasma snotters, saffron slimes, and dark-purple onibi, but saffron onibi are immune to Yannik's primary fire and secondary fire. Yannik is designed to be of White ethicity, Yannik's pronouns are he/him, Yannik is irreligious, Yannik is aroace, Yannik is a celibate, Yannik is childless, and Yannik is one of the adventurers of "Humetarmistan" along with Eric, Kabir, and Mateo.
Yannik's brothers are the male "humetarm" Eric and the male "humetarm" Kabir, and Eric's, Yannik's, and Kabir's father is the male "humetarm" Mateo. Mateo created Eric, Yannik, and Kabir asexually using some pieces of metal from the forearms of the corpses of Mateo that Mateo left behind before reviving himself after Mateo killed himself and the liverwurst from the liver of the corpses of Mateo that Mateo left behind before reviving himself after Mateo killed himself, due to Mateo being lonely after Mateo created "Humetarmistan" after Mateo killed the "hu-alien" that created Mateo. Mateo was also created by a "hu-alien" that Mateo was named after. Mateo was created with some pieces of metal and with the liverwurst made from the livers of the corpses of the other "hu-aliens" that were murdered by the "hu-alien" that created Mateo. The "hu-alien" that created Mateo also murdered Mateo with a corrosive gas chamber, but Mateo revived himself and Mateo killed the "hu-alien" that created Mateo. Mateo also created "Humetarm Heterodox Sikhism", "Humetarmistan", and the "one adventurer at a time" policy (prevents the adventurers of "Humetarmistan" from teamwork), and Mateo is the dictator of "Humetarmistan", but Mateo is willing to temporarily give his dictator privileges to his children when Mateo is adventuring.
Before "Eric & Yannik 5" got updated to version 4.1.1, "onibi-elemental" damage was known as "darkpurpleonibi-elemental" damage and saffron onibi caused "fire-elemental" damage rather than "onibi-elemental" damage.
