The king is too busy for voice acting, so I'll just ask for fan voice actors. In UNDERTALE, UNDERSWAP, and OUTERTALE, Asgore has a very low pitched calm voice. He is a big fuzzy pushover who everyone loves. He can sound wise sometimes (even when he isn't always) He's got a love for gardening and tea. He misses his ex wife Toriel. He's very awkward if he's ever around her. In UNDERTALE, He has a heavy burden weighing on his back as the king of the underground, and all monster kind, as he needs to collect 7 human souls to break the barrier trapping his people underground. He is a coward, and tries to shy away from his duty whenever possible. He is a good person forced to do a bad thing. In OUTERTALE, his voice and personality is the same, only the setting of being underground is changed to being in a solar system isolated from the rest of the galaxy. In UNDERSWAP, his voice is the same. His personality is mostly the same, only, he trades roles with his ex wife, so he tries to convince Toriel not to go through with the same plan classic Asgore has. Swap Toriel isn't nearly as cowardly as both Classic and swap Asgore. When toriel refused, he flees to a place in the underground known as Old Home (he named it, and you can tell he's bad at names) He has now adopted the role as the caretaker of the ruins. In UNDERFELL, Asgore is a wicked tyrant who is much more sinister than his UNDERTALE counterpart. His task of collecting 7 human souls is no burden, but rather exciting for him. Nobody dares to threaten the king. His voice is identical to Classic Asgore, but his personality is way less friendly.
