Yannik
Yannik is a short and freckled male humanoid robot with light skin, a blond quiff hairstyle, blue eyes, and blue forearms with white hands (Yannik's blue forearms with white hands can turn into blue arm cannons). Yannik wears a blue sleeveless leotard, and blue shoes with white socks. In "Eric & Yannik X" (after "Eric & Yannik X" got updated to version 1.5.0), in "Eric And Yannik Gotta Go", and in "Eric & Yannik 5", Yannik can shoot blue EMP grenades out of one of his arm cannons. In "Eric & Yannik X" (after "Eric & Yannik X" got updated to version 1.5.0), Yannik can also shoot blue EMP sticky mines out of one of his arm cannons, but he needs secondary fire ammo (which consist of light-green stars) to shoot said EMP sticky mines. Also, Yannik's blue EMP sticky mines are also mostly useless (except for defeating Don Glaber much faster). In "Eric & Yannik 5", Yannik can also shoot blue MIRV EMP grenades out of one of his arm cannons, but he needs secondary fire ammo (which gradually regenerates on its own, no light-green stars required) to shoot said MIRV EMP grenades. Unlike other projectiles, Yannik's blue EMP grenades, blue EMP sticky mines, and blue MIRV EMP grenades obey gravity. Yannik has high offense with low defense and mobility.
In "Eric & Yannik X" (before "Eric & Yannik X" got updated to version 1.5.0) and in "Eric and Yannik" and "Eric and Yannik 2", Yannik can shoot plasma filled balloons out of one of his arm cannons. In "Eric & Yannik X" (before "Eric & Yannik X" got updated to version 1.5.0) and "Eric and Yannik 2", Yannik's plasma filled balloons obey gravity and take seconds to blow up.
Before the release of "Eric and Yannik 2", Yannik's plasma filled balloons acted differently. Yannik's plasma filled balloons used to disobey gravity and explode if they hit anything.
