Little tip: if you do get him, use him and Lord pent to kill Kenneth.
Hint: Control Enemies
In the chapter where you get your first mine, set it down somewhere. Hopefully an enemy will step on it. When he does turn it off while it's exploding. When you go to resume chapter it will show the enemy getting blown up. When it does you can control the enemies!
Hint: Get Karla

Hint: Hidden Characters
Harken: At the level where it snows, after it starts to snow the 2nd time, if you have not killed more than 3 upgraded enemies (Sniper, Druid, etc.) Harken (a Hero) will appear in the upper left hand corner. Talk to him with Eliwood, Lowen, or Marcus and he will join your party.
Canas: Canas specializes in magic like Flux and Luna, the opposite of Erk's abilities. As you progress through the game you will eventually be asked to "Accept this side Quest?" When you are asked for the first time, select yes. You will be taken to a level that requires you to defeat pirates in order to get passage to an island. When you begin that level head on straight up. Visit the first or second house. Talk to Canas, he'll join your group.
Dart: Dart is in the same level that you'll find Canas. DO NOT fight him or his capitan, just talk to the capitan. Dart will join your group within the next few levels. You may be asked to accept another side quest. If so select yes.
Legalt: Legalt is a thief like Matthew. In chapter 19: Dragon's Gate, you will notice a thief in a red coat running around. He'll try to open two chests on the castle's right side, and will run back to where he first appeared and disappear. Use Lyn or Eliwood to confront him. Talk to him and he will join your group.
Hint: More Hidden Characters
Heath: Heath appears when Nils gets sick and you must protect him. Talk to Heath with a lord (Lyn, Hector, or Eliwood) to get him to join you.
Nino: When you go to protect the prince, talk to Nino on the way with one of the lords.
Farina: On Hector ch.25 (after you beat the game) you can get Florina’s brother but you must have 20,000 g to get him.
Harken: You can get him on the snowy level, when it starts snowing for the third time; he will appear with a couple of cavaliers and a Paladin. To get him, talk to him with Isadora, Marcus, Lowen, or Eliwood and he will join your party. He has some average stats, but has a good weapon, the Brave Sword. You get him if the Boss is Jerme.
Hint: Cheap Items
In Eliwood or Hector Hard mode get the extra chapter after Ch.18 The Dread Isle by finishing within 15 turns or less. Then take a thief and steal the silver card from the boss. The silver card lets the holder pay half price for all of the items he or she buys but the person you go to the armory or vendor with has to have the silver card.
