So...I'm in the mood for explaining the TGL characters(maybe not including Rumeidia), so...yeah, onward! :D

Marth

Name:Marth
Nickname(s):Ma-kun(by Roy),Marthy-boy(by Rumeidia),Marthy-san(by Ike)
Age:19
Height:5'9
Likes:His friends,Ike,training, the Sun, the moon
Dislikes:Being mistaken for a girl(though he's used to it, so...), Wario, Being teased about him and Ike
Love interest:Ike(Don't kill meee T_T)

My comments:It's Marth~! Ahh, I remember when I 1st saw some IkexMarth fan art of him. I thought he was a girl and was all like,"Pretty blue-haired boy and girl~ squee~" it wasn't until the artist who made the pics made a whole IkexMarth comic(where Ike and Marth had a child and the child was Sonic) I started questioning his gender XD So, I found out, and later on, I found some more IkexMarth fan art(which was FABULOUS, BTW) and fell in love :D er...yeah, basically my Marth is pretty nice, occasionally goes along with teasing Rumeidia with Ike, but...yeah, he's a nice dude and cares 'bout his buddies :D Oh, and Marth USED to have a crush on Roy, but his crushing faded away, but his slight interest in Ike is REAL, REAL I tell yooouuu >:D

Ike
Name:Ike
Nickname(s):Ikey-boy(by Rumeidia)
Age:19
Height:5'11
Likes:His friends,Marth,the Sun,meat
Dislikes:Rumeidia teasing him about him and Marth,psychopaths
Love Interest:Marth(Don't kill me D:)

My comments:Ikey~! He was the 1st character I ever bralwed with! When I got Brawl, my sister and her friends came over and played Brawl. Then, I got the chance to play(and since Marth wasn't unlocked yet), I played as him against my sis's bf, who was Bowser. And I kicked his @$$! YEAH! >:D Anyway, Ike is a good guy, too, he loves meat, and sorta has interest in Marth(but right now in the manga he's not too sure). Eh, he likes teasing Rumeidia sometimes, but she's got his respect.

Rumeidia
Name:Rumeidia
Nickname(s):Rume(by Ike, Marth&Link),Rume-chan,Sis(by Roy), Mama(by Toon Link), Woman(by Wario&Bowser)
Age:19
Height:5'8
Likes:Her buddies,Link,Toon Link,Summer,Most Spicyfood,Fighting
Dislikes:Wario,Bowser,Tabuu,her great grandmother,Dark Rumeidia
Love Interest:Link(I think you know by now)

My comments:Oh, Rumeidia, I created you after I started playing Brawl. I think you all get Rumeidia's personality:(most of the time)confident, spunky, doesn't give a dang to some stuff/people. And the reason for why she hates her great grandmother is a spoiler(AKIOH/AKIOH'S ROY DON'T SAY ANYTHING!), you'll find out in chapter 4 or 5
