His penchant for physical contact with Goku is likely a result of how surgical and formal people are around him, leaving him feeling somewhat starved for companionship.
When his future counterpart gets hugged by Goku, he likewise seems unfazed. To this end, he does not seem to have a problem with physical contact, even with strangers, as seen when he is unbothered by Goku's lively handshake. It is possible that Zeno is lonely, as almost nobody knows of his existence, and those who do fear his power, proving a barrier to friendship, as his attendants wait on him hand and foot and the Grand Minister only treated him as if he is royalty, blithely following his orders without question.
He immediately erased Frost when he tried to attack from outside the ring, and then threatening Universe 6's erasure to ensure it does not happen again. However, he does have limits to what he can tolerate. His flexibility, combined with his childish tendencies, also prompts Zeno to permit what otherwise would be rule violations in the Tournament of Power, such as permitting the Evil Containment Wave and use of the Potara earrings. He condoned Top's challenge to Goku as an additional fourth match to be witnessed, despite the end of the Zeno Expo. For example, he accepted Bergamo's proposal to rescind universal destruction were he to win against Goku, despite his earlier decision. At the same time, Zeno is also shown to be flexible, tolerant, and even willing to go back on his word on occasion. riches, power, etc.), all existence would have been erased, including the exempt universes as that would have meant that the winning universe was no better than the erased ones and that the exempt were no more worthy of existing than the others. But if the wish was to be an egotistical one (e.g. like restoring all the erased universes as it was the case). In spite of all this, Zeno and his future counterpart, at least in the anime, showed wisdom worthy of supreme beings, as the Grand Minister revealed that both of them intended the tournament prize, the wish of the Super Dragon Balls, to be used for an incredible virtuous act (e.g. Furthermore, he seems to be incapable of understanding the horrible action of erasing trillions of lives, since he and his future counterpart wonder why everyone in the Tournament of Power stops fighting after witnessing an entire universe getting erased. He and his counterpart also said "squish" in a light-hearted, delighted tone when they were erasing Universe 3. He also shows some degree of sadism, as shortly after erasing Universe 9, he proceeded alongside his future counterpart to say "bye-bye!" in a joking tone, as well as being heard laughing childishly while erasing the universe. Even more, this indifference seems to extend to the gods themselves, seemingly rendering him a remorseless being to his peers, and was shown to not even be affected by Roh's horrified crying out of his name. He apparently wished to decrease that number further for some time, giving no excuses for such a decision beyond saying 12 universes are a bit too much to keep track of, with the Tournament of Power being the perfect opportunity to do so. In the manga version of the Universe Survival Saga, however, it is implied by Grand Minister that the real reason why he destroyed the aforementioned six universes was simply to get rid of what he felt were too many universes. Like many deities, such as the angels, Zeno seems to have a general indifference about life, as well as all the other stuff within the multiverse, having destroyed six of the eighteen universes after a bout of anger, and also destroying several planets in a game he played with his future self 202 times.
He typically has a blank expression on his face. He wears a black and white shirt underneath, with the kanji for "all" (全) on the front. His main attire is a magenta and yellow lined coat, with yellow pants and magenta shoes.
He has small round eyes, and small rounded grey "ears". He primarily has sky blue skin, except for two sections from his ears to the middle of each eye on both sides of his head, which are purple. Zeno is very short and small, with a rather large oval-shaped head.
