Liy

While I, Liy, am pressed. And I’m impressed. Liy is a contestant in Battle for BFDI. She originally appeared as a character in the joke video "BFDI APPISIOTE 225555555!!!!!", in which she was brown and white instead of light blue.

Liy, being a light switch, has the ability to toggle her switch. She first appeared onscreen in animated form in BFB 1, when she asks Tree to help her get Teardrop to talk.

Before Battle for BFDI
Liy (arguably) made her debut in BFDI APPISIOTE 225555555!!!!! as a cameo. She was seen briefly when Michael Huang shook the camera at a light switch on a concrete wall.

Battle for BFDI
Liy made her animated debut in Getting Teardrop to Talk. In it, she asked Tree to hold Teardrop's jaw open while she fiddles with her vocal cords in hopes of making her talk. Tree declines the offer and "leafs". Ice Cube later appears, and Liy asks if she is cool. Ice Cube is unsure, but Leafy interjects and says Ice Cube is cool, along with everybody else. Liy asks Icy again if she wants to help her make Teardrop talk. Ice Cube says "Yeah!" and she and Ice Cube fiddle with Teardrop's vocal cords. They immediately start playing around with TD's vocal cords, and Liy says she can almost hear Teardrop's voice. Bracelety is seen cheering Icy, and Clock asks her why she's condoning Ice Cube "torturing" Teardrop. After Clock's argument with Bracelety and Fanny, he tells Liy to stop trying to make Teardrop talk. Liy refuses, and then Clock asks Icy if she wants to stop. Liy interjects that Icy should make her decision, but Ice Cube says she wants to stop. Clock appreciates Ice Cube's decision, but Liy becomes frustrated with Ice Cube and says she thought that Ice Cube was cool. Icy apologizes and continued along with Liy to try to make Teardrop talk.

In Lick Your Way to Freedom, Liy eyed Foldy when Black Hole freed her from the Jawbreaker.

Liy bought one quadrillion fork repellents in Why Would You Do This on a Swingset. (1,000,000,000,000,000)

Personality
Liy is seen as somewhat of a pushy and rather manipulative contestant, similar to Golf Ball. She can be seen trying to force other contestants to do what she wants, like trying to make Ice Cube wiggle Teardrop's vocal cords, or by trying to get Clock to form a truce with her.

However, Liy can also be seen as a curious individual, who manipulates others in the search of knowledge, such as wondering what TD has to say, or wondering what was at the top of Bell's string.
