Heavy & Ralsei (Team Fortress 2 x Deltarune)

The Heavy Weapons Guy (true name Misha) is a huge, burly, strong but soft-spoken mercenary, armed with big miniguns he loves and cares for like children - like his beloved Sasha - and healing sandviches. The Heavy proves to be both an unstoppable force and a polite, noble man. He originates from Team Fortress 2.

Ralsei is a goat creature from the Dark World and a prince without subjects, as he puts it. He's a sensitive and caring soul, reaffirming and supporting his friends just for the sake of being kind. When fully adorning his gear, his body is hidden beneath green robes with a black heart sewn into it and a green hat. Should he remove his hat, his snow-white fur will shine. No matter how he may dress, his dorky glasses and pink scarf remains a constant. His magic, although can serve to harm, is often used to pacify the enemy or heal comrades. He originates from Deltarune.

They're both aiming to seal as many Dark Fountains as they can, in an effort to prevent THE ROARING.
