A distant descendant of the Hero-King Marth, Chrom is the prince of the Halidom of Ylisse, which now stands where once stood the nation of Archanea. More a man of action than of politics, Chrom leads a group of soldiers called the Shepherds, as they protect the country’s people from bandits, and the ever-growing threat of the neighboring nation of Plegia. His weapon is the Exalted Falchion, a treasure inherited by his family from the Hero-King.

Chrom first appeared at the 4th world, but he wasn't a Smasher. Instead, he helped out the Robins with their Final Smashes, becoming an Assistant Trophy. But he finally got his chance at Ultimate and became a Smasher and an Echo Fighter to Roy. This doesn't bother him, since being with Lucina and his partners is good reward enough for him. Although, a part of his essence is still an Assistant Trophy, not fully releasing him from this situation.

For his voice, I'm looking for someone who can sound as close as possible to Matthew Mercer. Check out this link for reference:
