Creating multiple sprites (Novice Cocos2d Question)

I have a CCLayer class where I create an animated sprite that is the "hero" for the game. Now, I am trying to create multiple enemies for him to fight, and I'm having trouble. I want to create a class called "Enemy" that holds everything relevant to the enemy, and just create multiple instances of that class for all my enemies. How do I go about doing this?

Here's the class I have so far (where i create teh hero, called "_bear".

#import "FightGame.h"
#import "SneakyJoystick.h"
#import "SneakyJoystickSkinnedBase.h"
#import "ColoredCircleSprite.h"
#import "CCTouchDispatcher.h"
#import "GManager.h"

CCSprite *player;
BOOL _moving, _crouched, _jumping, _actionTouch, _maxJump, _leftJumping, _rightJumping,         _punching, _kicking, _touchSet;
int startX, startY;

@implementation FightGame

@synthesize bear = _bear;
@synthesize jumpAction = _jumpAction;
@synthesize walkAction = _walkAction;
@synthesize punchAction = _punchAction;
@synthesize kickAction = _kickAction;
@synthesize crouchAction = _crouchAction;
@synthesize currentTouch;

+(id) scene
{
// 'scene' is an autorelease object.
CCScene *scene = [CCScene node];

// 'layer' is an autorelease object.
FightGame *layer = [FightGame node];

// add layer as a child to scene
[scene addChild: layer];

// return the scene
return scene;
}

// on "init" you need to initialize your instance
-(id) init
{
// always call "super" init
// Apple recommends to re-assign "self" with开发者_JAVA技巧 the "super" return value
if( (self=[super init] )) {
    /*player = [CCSprite spriteWithFile: @"Person1.png"];
    player.position = ccp( 50, 100 );
    [self addChild:player]; */

I could just give you the answer on this but that is useless. You need to crawl before you can run. Go to RayWenderlich.com and do at least some of his Cocos2D tutorials. You will get yourself up to speed quickly enough.
