However, his good self-control does not negate the fact of extreme grudge and vindictiveness, so that any insult thrown towards his team will not go unnoticed

Thallium, in turn, does not like him for this, and can often think about whether to remove the stick that is trying to get into the wheels, but keeps himself in hand.

One of his personal non-favorites, Shadow turned out to be on his list. Why? Because the bearer of title "The Ultimate Life Form" immediately realized that something was wrong with his blue rival, so he was one of the first to guess about his nature. Almost never crossed paths with him unnecessarily

Then, of course, Thallium will easily get angry, because although he knows how to control himself, he can still throw childish tantrums and behave immaturely, and in his case with super-form, this is also fraught with the fact that there are almost no restraining factors.

When he does not try to hide, Thall behaves openly indifferent to everything outside his "circle of loved ones", mostly very cold and calm, but it is easy to unbalance him if you press the right buttons or deliberately provoke him.

By nature, in his normal form, he tries to imitate his old self, but sometimes his depression, fatigue, cynical remarks or general gloom break through the mask. His behavior also varies greatly depending on whether he is communicating with one of his friends or with a stranger.

Thallium deliberately slows down his movements and barely touches anything, always very careful, but so that it would not be too obvious because it doesn't cost him anything, for example, to take and break a cup with two fingers if he squeezes too hard.

He moves from two forms both at will and unconsciously, but always keeps himself in control in front of others, because he has to limit himself greatly in everything, even in everyday things

In principle, nothing prevents him from eliminating any threat in his path anymore, and there is little to stop him, because Thallium simply cannot get out of his super-form, consider that the Chaos Emeralds merged with his body, but because of their power, he became unstable himself.

Sonic has a grudge against him out of personal hatred, remembering the past, but he still leaves him alive not because he is against violence or murder, but simply because he does not want to bother his friends. No one need to bother about this nonsense, their ol' good Hero can take it.
