Tentro is a very strong and smart Mixel. Despite these powerful strengths, he has some horribly serious confidence issues. He is a Mixel of few words and emotions and has a tendency to stick to the sidelines while feeling extremely awkward and shy around the other Mixels. He often likes to be alone with no Mixels around him and visits places that have a huge lack of crowds. He normally feels comfortable mixing with his fellow Flexers or friends that he used to knows a lot, especially Lunk.
