Hey Amanda I just felt lazy and gotten fanarrs of your boyfriend sadly there isn't much since he is only in the seven deadly Sins for 10-8 minutes. I found gifs and fanarts of him. Zeldris and Geldas  faces when they heard Meliodas and Elizabeth had a child killed me!!! And a child being born between a demon and vampire isn't heard of either!!!

Awwwwwww he is so flipping cute!!! And he is shy. It is amazing how Tristans top hair looks exactly like Meliodas hair minus the part that is in the air.

So Tristan and Lancelot is in "Gets mistaken for a girl" club. I feel bad for both of them that boys flirt with them but they got used to them. Lancelot already cut his hair. Tristan left it like that.

And this how Lancelot looks right now. That scar he has Tristan gave that to him in a battle or match. Wow I never noticed Tristan had similar clothing to Meliodas!!! He wears a tie! XDDDD But he is just 10 years old!!!

Lancelot is half human and half fairy since his father was human(Ban) and his mother was a fairy(ELANIE). So far nothing. They look like humans so far. Man I wonder what powers Lancelot have!!! Cause Ban can take any hearts from someone's body and ELANIE had miracle wind which was so strong Ban was blown away!!!

We already know that they are members of the four knights of apocalypse. So Tristan, Lancelot, Percival and an unknown person.

Percival is the knight of death, we don't know the knight of war yet, Tristan is the knight of Plague, and Lancelot is the knight of starvation. The four knights of apocalypse destroyed Camelot. I'm sad that Aruther is evil as they say. 

Even though he is the Prince his dream is to be come a holy knight to protect his Kingdom, Liones. Like he said on the end of seven deadly Sins that he would fight them all. He is really brave for a ten year old. I would call him a Gryffindor.

"The great holy knight Tristan shall punish you!"

Hehe Chibi Tristan never gets old. He tried to be sneaky but Elizabeth found him.

Like Father like son. He has a flipping tie dang Meliodas made a mini version of him. It is cute how "fancy"  he looks.

"Did I do it right?"

"Father! Wake upppppppppppppppppppppp!"

I wonder why Tristan was to wake up Meliodas. I still don't get how people think he is a girl.

Oooo so that's how Tristan started loving Ramen 🍜!!!!Thanks Meliodas!

"Hmmm? What is this?"

"I'm watching"

Hahahahahhahahahahahha Tristan be a little spy on his parents 

 He is so young to see Meliodas do that!!! Man that ten year old has seen too much

And for the last photo

This may be Tristan Demon/ Goddess form. We may never know he is a mixture of the two sooooo I'm not sure.
