I think that you need to put the opposite of every word like =
Hola, Soy Peter soy muy flojo, no me gusta leer, tampoco soy tan inteligente, nunca me ha gustado correr y no soy fuerte ni activo,
(something like that)
Hola, me llamo Voldemort, Soy muy Desagradable y triste, No tengo pelo, no soy guapo ni joven,
And then in the exercise you need to make the same but with another fictional character and put descriptive information (about the character)
like things that he/she/it =
likes/dislikes
Personality
Physical traits
