各個

各 = 口 + 夂 : Mnemonic symbol: each and every (各) one of us is made of atoms, of which most were created in a star (from lighter atoms). That's why I choose to represent this character by a star. Guy Fawkes (g) is stepping on a mandarin (口) with high heels (夂) in the bathroom of the elevator (e4). As he squeezes, the mandarin suddenly explodes in a rain of stars (各). Each and every (各) one of them is shining brighter than the others.

个 = 丨 + 人 : Mnemonic symbol: Neanderthal Man (人). Neanderthal Man (人) needs to use the elevator's bathroom (e4) but it's occupied by Guy Fawkes (g), and there's only space for one individual (个). Impatiently Neanderthal Man knocks on the door using his dinosaur bone (丨).
