Steele Personality is the following: The most famous dog in Nome, Steele takes pride in his popularity amongst both the village humans and the dogs, often showing off in front of his admirers. He is incredibly arrogant, often swaggering up to females in the hopes of impressing them with nothing but his looks and reputation. 
His occupation is highly motivated by fame among both human and animals around Nome. 
He also likes Jenna, but she sees through his lies and loves Balto the pure-hearted instead, which further strengthens Steele's hatred and jealousy of Balto. He is also dishonest, claiming that Balto and the rest of the team had died, but at the end of the film, when everyone finds out, all of his lies cause him to be shunned and disliked by those who used to respect him. He is mean and sarcastic when he gets on Balto's nerves. He is sneaky, treacherous, envious, extroverted, loathsome, eccentric, temperamental, empathetic, egotistical, very talkative, somewhat of a pervert and energetic as well. He is also heartless, as he prevents Balto and the sled team from returning with the medicine, not caring that the children will die if the medicine isn't delivered.  
Someone told me that Steele is Sadistic. But Steele does not have the personality of a Sadistic type of Character. Steele has the Characteristics of being Heartless but not Evil, Cruel, Narcissistic, etc. Ironically Balto Fandom made Pictures and Stories that way. Balto Fandom made the ideas Steele does not have Hatred and Jealousy of Balto. Steele is not mean and sarcastic toward Balto. In-fact Steele is in love with Balto, Steele having Sex with Balto, Romance Couple, etc. There is an idea Steele is a Bisexual or Gay!?. Ironically I love the ideas of Steele being a Good Dog and having a Second Chance, Redemption, etc. Based on The ideas that Steele was never Evil. Balto Fandom has Pictures and Stories Steele Forced Sex, Killing, Kidnapping, etc. I don't think Steele would act that way. I have always pictured Steele without the Hatred and Jealousy, not as an Evil Character. Based on the fact Steele only actors Mean and Sarcastic toward Balto over having Hatred and Jealousy for him. Steele from Balto 1 is much better. Steele shows off more of an Envious Type of Dog. At the same time, Balto Fandom makes him Evil, Cruel, etc.
