Before Ferdinand von Aegir was Ferdinand von Aegir, Seigbert was Seigbert... In Heroes, anyway. Fates doesn't have voice clips for selecting a unit.
Seigbert's a cavalier with very balanced stats that are high all around. He's pretty much just a nice filler unit who's likely to have better stats than your other cavaliers, but without any of the time they had to build supports or be useful. That's... about it, really? I don't know what to say about this guy.
Gallant is a poor man's Forceful Partner, except it works for all girls and not just Corrin, so he's not a bad unit to pair with one of your second gen girls to make them hit harder. Seigbert can reclass to Malig Knight if you want him to give boosts more relevant to a magic user, something I might end up doing if I do pair him with Ophelia. If you want to use him as a combat unit, it can be a good idea to Offspring Seal him into Great Knight and them promote him into Wyvern Lord, WK's a good class and he'll start off with axe rank if you don't recruit him too early.
My Seigbert in particular has very similar stats to Peri, who is his mother. He's basically Peri with the edges smoothed off, he's slightly less strong, fast, and resistant, but better in every other aspect. Half the people who play this game usually pair him with Charlotte, who makes him even faster and stronger with more HP in exchange for worse defenses. Charlotte!Seigbert is probably very good?
Yeah I've really got very little to say about this guy. I told you these analyses wouldn't be very good! I'm sure someone on the internet has a lot of insightful commentary about the uses of kids in these games.
