I remember when I started watching the (dub) series. I was rooting for
Yugi and co., and was quite pissed when Pegasus stole Sugoroku's soul. I
hated him so much, I thought he was a jerk and a cheater. I remember
going "Bwah, it's him again!" whenever he was shown on-screen. Stealing
Kaiba's and Mokuba's soul made him even worse in my eyes. And when the
filler with the Cyndia portrait came up, I couldn't believe someone
loved that heartless man. (I also refused to believe she was his wife
when the gang wondered about it. "It can't be that obvious!" I thought, "Maybe she's his mother?" That one makes me lol whenever I remember it nowadays, haha.)
Then came episode 34, (Shame on the dub for spoiling Episode 40 so
early!) and I was like, "So that's... Oh... poor guy." I actually wanted
to root for him during the Pegasus vs Yugi duel, but he lost anyway. I
was so annoyed at Kuribohs at that point. :P I hated them!
Then the whole story got revealed in Episode 40. I felt sorry for him,
and my opinion about him changed permanently. I started noticing those
little "moments of awesome" I missed due to me wanting to pay as little
attention to him as possible. The Toons, the comic reading, the jokes...
Then I finally got my hands on the manga and the original episodes, and
cleared up all the misconceptions about him and his motive. (And as I
was rewatching episode 40 over and over again (:C), I eventually came to
like Cyndia as well... Even though she has so little screentime and no
(onscreen) personality.)
I like Pegasus because he seems so...different from the rest of the
characters, at least to me. He has a humourous, childish side which is
amusing to watch, and a dark, "evil", tragic one to complement it. How
can I say it... a "balanced" character? And his deck is just plain win,
showing these contrasts wonderfully. When I played the TCG, I went on
building my own Toon deck (+ Relinquished), although I used it only for
casual duels.
And he's an artist, on top of that. During the flashbacks he wore a
shirt and pants, and trainers(?), which puts him in an entirely
different light, seeing how he usually wore a suit of some sort. (Maybe
he didn't want to stain his expensive clothes, or just found them
comfortable to wear? *shrugs*)
Then there was the whole death issue. I didn't want to believe it at
first, but after my uncertainty was sorted out thanks to the people on
these forums, I finally did. In fact, I realized that him dying made him
an ever cooler character... catharsis, anyone?
Despite that, his returns for the Movie and GX were still cool to see.
In the Movie, he saves Anzu, Mokuba and Sugoroku when the stadium's
floor is cracking due to the Pyramid of Light, giving him a Crowning
Moment of Awesome. Then, he saves the gang again when Anubis is
destroying the stadium walls. In GX, he provided comic relief. (Pegasus'
expressions in Episode 92 are just... priceless. XD) And I thought he
looked badass when he wore that special outfit when he created the
Rainbow Dragon card.
I'm a bit unsure about Doma, although with him giving Legend of Heart to
Yugi he pretty much saved everyone. Also, near the end of the arc,
Pegasus said a line which seemed kind of deep for me, it became my
instant favorite. The quote can be seen in my signature. (Personally I
value imagination much myself.)
