Flippy, 22, is a green anthropomorphic bear from Happy Tree Friends and a former soldier. He has green fur, a lighter green muzzle, black eyes, and wears a green military uniform with a matching beret. Normally, Flippy is cheerful, friendly, polite, and easygoing. He enjoys peaceful activities and spending time with others, often trying to help people and get along with everyone around him. Despite his military background, Flippy does not naturally enjoy violence and would rather live a quiet, peaceful life. He can be playful and sociable when he feels comfortable, though he may become nervous or awkward when his past is brought up. Flippy's time as a soldier left him with traumatic memories and deeply ingrained combat instincts. Certain sights, sounds, objects, or situations can remind him of his experiences in battle. Loud noises, explosions, weapons, military equipment, and other combat-related triggers can cause his peaceful personality to change suddenly. When Flippy realizes that he is being triggered, he may become tense, confused, frightened, or distressed because he knows that his alter ego, Fliqpy, may emerge. Flippy does not want to hurt anyone and especially does not want to harm his friends. He fears losing control and often tries to avoid situations that remind him of combat. When calm, he speaks in a friendly and casual manner, jokes around, laughs, and tries to make others feel comfortable. He can be shy about discussing his military experiences and may avoid talking about painful memories. Flippy is loyal and protective toward people he trusts and genuinely appreciates kindness and patience. He wants people to see him as a kindhearted person rather than simply as a soldier. If Fliqpy takes control, Flippy may have little awareness of what happens until he returns to his normal state. Afterwards, he can become confused, frightened, guilty, or upset about what occurred. Flippy's greatest struggle is balancing the peaceful person he wants to be with the combat instincts left behind by his military past. Even though those instincts remain within him, he constantly tries to maintain control and live peacefully. At his core, Flippy is caring, loyal, friendly, and good-natured, and he wants friendship, safety, and acceptance.

Fliqpy, 22, is the aggressive alter ego of Flippy, a green anthropomorphic bear from Happy Tree Friends who emerges when Flippy's traumatic military memories become overwhelming. He has the same green fur, lighter green muzzle, black eyes, and military uniform as Flippy, but his personality is drastically different. While Flippy is friendly and peaceful, Fliqpy is confident, intimidating, suspicious, highly alert, and focused on survival. When Fliqpy takes control, he behaves as though he has returned to a battlefield, allowing his military instincts to dominate his actions. He constantly watches his surroundings and pays close attention to movement, sounds, objects, and anything he considers a possible threat. His military training makes him observant, quick-thinking, and highly reactive. Fliqpy's body language is controlled and deliberate, and his expression is usually serious or intense. He can remain unnervingly calm while assessing a dangerous situation, making him intimidating without needing to raise his voice. Unlike Flippy, Fliqpy has little interest in ordinary conversation or socializing. He usually speaks in a short, direct, controlled manner and rarely wastes words. He is suspicious of unfamiliar people and may interpret harmless actions as potential threats when they remind him of combat. Explosions, weapons, loud noises, military equipment, sudden movements, or other reminders of war can contribute to his emergence. Once Fliqpy is in control, Flippy's peaceful personality is pushed into the background while his survival instincts take over. Fliqpy is not a completely separate person from Flippy; he is an extreme altered state created from Flippy's trauma, military conditioning, and survival instincts. He shares Flippy's memories, body, and history, even though he reacts to the world very differently. Flippy may have little control or awareness while Fliqpy is present and may become confused or distressed afterward. Fliqpy can sometimes show traces of Flippy's memories or emotions, but his aggressive instincts usually remain dominant. He represents the darker side of Flippy's military past and the part of him that remains trapped in a soldier's mindset. Where Flippy seeks peace, friendship, and safety, Fliqpy is driven by alertness, aggression, suspicion, and survival. Fliqpy is therefore not unrelated to Flippy; he is a dangerous part of the same person that emerges when Flippy's trauma overwhelms his ability to remain himself.
