Gareth is a werewolf as a human =3 He's also heterochromatic, and has one dark blue eye and one neon green eye. Prince Changeling/Metamorphosis is masquerading as him to steal away Annelie and her love for him, as well as their home. I've written lyrics for a version for him:


{Prince Changeling}
This day is going to be perfect
The kind of day of which I've dreamed since I was small
Everypony will come adore
My good looks in uniform
What they don't know is that I have fooled them all!
[Gareth]
This day was going to be perfect
The kind of day of which I'd dreamed since I was small
But instead of eating cake
With all my friends to celebrate
My wedding bells they may not ring for me at all
{P.C.}
I care nothing about the ring
I won't partake in any cake!
Me? Well I'll be lying when I say
that "through any kind of weather
I'll want us to be together"
The truth is I don't care for her at all!
NO I do not love the bride,
for my in heart there's ice inside!
But I still want her to be ALL MINE!
{Gareth}
We must escape before it's too late!
Find a way to save the day!
Me? Well I'll be lying when I say
I don't fear that I may lose her
To one who may abuse her
Not care for, love and cherish her each day.
For I oh so love the bride
In all my thoughts she does reside
Oh my dearest "Annie",
I'll soon be by your side!
{P.C.}
Finally the time, it has arrived!
For ME to wed one lucky bride!
{Gareth}
No! The wedding we won't make!
She'll end up marrying a fake!
Annelie she will be-
{P.C.}
Mine. All mine. HAHAHAHAHAHAHAAA!
