Dinosaur King story Rex X OC Male Who was that?..

The D-Team?

Mason P.O.V
~~~~~~~~~~
I just got called in as back up, apparently there is some difficulties getting the Spinosaurus so dad is teleporting me to their location. "You ready Blade?, though I doubt we'll do anything" I asked her, blade looked at me and nodded. I sighed, it's been so long since I've been on a mission, hmm oh looks like we've arrived. " hey guys what's up?" I said to the gang, "Mason?! What are you doing here? You can get hurt!" Ursula said to me, she's like me mom, I see a boy about to grab terry's card but Ursula quickly grabs him. " My terry might have lost but he's my loser" Ursula told them, wait who are they?

3rd P.O.V
~~~~~~~~
"Look guys it's the old lady!" Zoe said, successfully angering Ursula, "What did you say..." Ursula said and hit Ed and Zander as they laughed. " You obviously need to learn the difference between old and experienced!" Ursula yelled at them, "Oh sorry, I guess I thought they meant the same thing" Zoe said. Ursula sweat dropped, "Well there's a big difference.." She continued but got cut off as she slowly looked up at the three dinosaurs.

Mason was quietly observing, staying out of sight, he turned Balde into a card incase he needed her.

"And you can sure I'll be back to explain it another time!, but for now the alpha gang must be on there way!" Ursula said as the dinosaurs tried to get closer but a velociraptor hit them slightly, making the three jump back.  

Zoe, Max and Rex let out a gasp in quick shock and the alpha gang a sigh of relief, as the velociraptor stood in front of them protectively.
"I would put those three back into their cards before I do it for you" An unknown voice spoke, unknown to the D-Team but not the alpha gang, " I'm sure Blade would love to play, right girl?", the velociraptor now known as Blade responded with a roar.

"A velociraptor..." Rex gasped out, "Mhm she's a beauty right?, I hate to cut this short but we must be going" the voice finished as a light surrounded him, Blade and the Alpha gang. "Wait who are you!?" Max called out but got no response, it was too late they'd already left. "Who was that?" Zoe asked no one in particular, Rex hadn't said a word yet. Rex had noticed a note on the ground, "Hey guys!, look a note" Rex grabbed it and read it out loud.

The note read,
So you're the D-Team, well maybe dinosaurs will be saved, look I'm not with you nor am I against you. But I'll let you know, if you hurt the alpha gang or my Blade you will have hell to pay. But for now you won't have to worry about me, and I'll say it again. I can be your worst enemy or your best ally, your choice.

The D-Team all stared at Rex and the letter, wondering just who this person was, and if they would ever get an answer.

*Back at Zeta point*

"Yes for once you idiots don't fail!" Dr.Z said, Mason stood at the back of them with Balde in his arms. "Hey dad is the move card complete?" Mason asked him, "Oh yes it is, I checked on it as you asked, my boy you're making move cards now, I'm so proud" Dr.Z said as he opened a tube. Mason grabbed the two cards, " Perfect thanks dad, hmm I wonder if I'll ever have to use these on them.." Mason said the last part quietly. He left to go try these move cards, grabbed his custom scanner with Balde followed him excited to try out her new moves.
For some reason he couldn't stop thinking about the blonde boy, a small blush crept on his face but he quickly shook his head trying to focus. "This is gonna cause problems ain't it" Mason said out loud, Blade tilting her head at her partner.
