In the Miraheze Wiki, Hyperlaser is said to “present himself with a stern, no-nonsense disposition.” Some of his interactions with other Phighters go along the lines of him “scolding or questioning them for playful and careless behaviour on the battlefield, with the intention of getting them to focus on the task at hand; he doesn't do it out of annoyance, but rather from concern that his fellow Phighters will be lost in a similar manner to the people from his past.”  -  info & quotations from:  https://phighting.wiki/Hyperlaser/Lore
