From the Super Mario Wiki
Richter Belmont is a vampire hunter from the Castlevania series of games, and the descendant of Simon Belmont, who debuted as the main protagonist of Castlevania: Rondo of Blood. Richter faces the resurrected Dracula in the year 1792, storming Castlevania after the town of Aljiba was burned by Dracula's forces and innocent maidens were kidnapped, including Richter's girlfriend. He is a playable fighter in Super Smash Bros. Ultimate.
Super Smash Bros. Ultimate
Richter makes his Super Smash Bros. debut in Super Smash Bros. Ultimate as a third-party character. He appears alongside fellow Konami characters Solid Snake and Simon Belmont, Sega's Sonic the Hedgehog and Bayonetta, Capcom's Mega Man, Ryu, and Ken Masters, Bandai Namco's Pac-Man, and Square Enix's Cloud Strife. He and Simon were confirmed to be in the game via a Nintendo Direct that took place on August 8th, 2018. Richter is voiced in English by David Vincent, reprising his role from previous Castlevania titles, including Portrait of Ruin, Harmony of Despair, and The Dracula X Chronicles; and in Japanese by Kiyoyuki Yanada, his voice actor in Symphony of the Night.
Richter is classified as an Echo Fighter of Simon, with his moveset and animations being based directly on Simon's (although the two actually take inspiration from each other). Richter's special attacks are Axe, an ax that is a powerful projectile; Holy Water, a multi-hitting projectile, with a blue flame that does aura damage instead of an orange burning one that does flame damage; Cross, a projectile with boomerang-esque properties; and Uppercut, a powerful uppercut that functions as his recovery move. Richter's Final Smash, Grand Cross, is functionally identical to Simon's identically-named Final Smash.
In Simon's debut trailer, he saves his ancestor Simon from Dracula's attack, and shouts a variant of his famous line from Castlevania: Symphony of the Night (quoted above), "Die monster. You don't belong in this world!"
Similar to King Dedede in Super Smash Bros. Brawl and Lucina in Super Smash Bros. for Nintendo 3DS / Wii U, Richter's name is announced differently in the Japanese version to reflect the pronunciation in that language. This trait is also shared with Simon and King K. Rool.
