There are two pregen 5e fighters. This one is built to be a "leader of men" / "great tactician" concept. It uses the stock human and champion fighter, with the Soldier background. The other is a haughty, sneering high elf fighter with the eldritch knight subclass, and is more interesting and more effective than this one.

This fighter is not a very good contribution to the party unless your group is using Basic Rules Only characters, or not using Feats. Here are some of this fighter's drawbacks:

• Dex is a terrible "dump stat" to take for a fighter. Especially a Champion. 9 Dex means poor Dexterity saves, low initiative, and poor Acrobatics. The Remarkable Athlete class feature is wasted because of the low Dex. If this character's Dex and Int were swapped, it would be better. I get that the idea is to make this character a "leader of men" type with History and Intimidation, with decent Int and good Cha to back them up.

• At level 10, the character's damage output is low, with two attacks at 1d8+5. Using Splint Mail at level 10 seems odd, since plate would/should be affordable by then. Just using their swords, the elf has better damage output and only 1 lower AC (the elf can also cast Shield to temporarily boost their AC).
